Waterproofing the foundation rolled What is the better material. How to use rolled waterproofing for foundation: the choice of materials and laying technology. Price of waterproofing foundation

The construction of a highly reliable foundation for the house under construction is always paid special attention. This is not surprising - the duration of the trouble-free operation of the building, and by and large, the safety of living in it is always directly dependent on the strength and stability of the base. When creating a foundation, simplifying established construction technologies should be categorically excluded, ignoring the requirements for the accumulation of the process or reduce the cost of common estimates, the use of low-grade materials.

As neither paradoxically, it may sound, but the powerful design of the foundation, created in all the rules and having a solid storage margin, still remains very vulnerable to different external influences, and first of all - to moisture. Protection of the base of the building from the destructive action of water is one of the key tasks, the importance of which, unfortunately, some beginning builders simply overlook. There are many different ways to solve this problem, and in the field of individual construction, the greatest distribution has won rolled materials. About this technology and will be discussed in this publication.

Why do not pay special attention to the foundation waterproofing issues?

Before switching directly to the consideration of technology of waterproofing the foundation, it seems the need to still give a novice explanation master, which is why this construction stage is so important, and to which consequences may lead to the absence or failure to protect the foundation of the house from the impact of moisture.

For a start, let's see in which water layers can be placed in a particular state.

• The upper layers of the soil, including fertile soil, always contain a certain amount of moisture, which penetrates there due to the loss of atmospheric precipitation, the melting of snow or other ways - for example, a straight spill of water when carrying out the irrigation of the site, when the car washing, during the accident on the water supply and In other similar situations.

It is understood that the concentration of moisture in the upper, so-called filtration layers of the soil is a constantly changing value that is interconnected with the established weather conditions, the time of the year, the normal or abnormal amount of precipitation, etc. But it happens that if in the thickness of the soil close to its surface there is a waterproof clay layer, then this moisture is going to a rather stable aquifer, which is often called the rope. And such a rigor has already been able to bring a lot of additional hassle, since, in addition to capillary penetration into the walls of the foundation, a certain dynamic impact is also capable of providing a certain dynamic effect.

To reduce the impact of moisture in the upper layers of the soil, a proprietary and constructed system of storm sewage is correct.

Livnevka, about the importance of which some simply forget ...

To assemble and remove the water dropped by the rain or formed in the snow melting in the spring, preventing the arms of building structures, get rid of the permanent puddles in the yard, protect the plot from the fear - all these problems should decide whether the individual publication of our portal is dedicated to the independent creation of which.

• All layers always contain a certain amount of water, which is held in them due to the capillary qualities of the soil. Here you can already talk about a fairly stable concentration of moisture, which is not particularly influenced by external weather changes or time of year.

Dynamic exposure to the foundation walls This condition of water does not have - everything is limited to infiltration into the thickness of the material. Usually, it is not too thick enough to counteract this, but a solid waterproof layer of waterproofing. True, for sections with increased saturation of soil moisture, for swampy locations, it is impossible to do without creating a drainage sewage system.

Sections with high humidity of soils require drainage systems!

If the ground in the construction site is clearly overcooked, or aquifer is located close to the surface, it is required to create a system that allows you to constantly remove excess moisture into safe places. How - read in a special publication of our portal.

• Finally, the plot can be close to the surface of the aquifers - this is already depends on the characteristics of a particular area. The depth of their occurrence is different, but often they are located just 5 ÷ 7 meters from the surface of the Earth. The degree of population is the value of the non-permanent, also depending on external current conditions. Visual proof may be fluctuating the water level in the well.

This state of affairs requires the maximum protection of the foundation in its deep downstream, that is, well-thought-out multilayer waterproofing of all structural elements. In addition, an effective drainage system becomes extremely important.

Now a few words about how moisture is capable of negatively affect the design of the foundation.

• From school bench, we all know the chemical formula of water, but what falls out with atmospheric sediments or penetrates the foundation through the ground - very far from the notorious "Ash-two-O". The moisture can be literally oversaturated with aggressive chemical compounds of organic or mineral nature - industrial emissions, automotive exhaust, spilled petroleum products, agricultural chemicals and many other are dissolved in it.

Such a "chemical attack" on the concrete does not pass without a trace - its structure may vary, which leads to disorders of the crystal lattice, the emergence of erosion processes, gradually shrinking the outer layers of reinforced concrete construction.

• Where the erosion and shower of concrete began - with time, the reinforcement of the design and reinforcement. And then the corrosion of metal will be accepted for its "black case". Moreover, it is fraught not only the loss of the strength of the reinforcing frame. At the site of "eaten" corrosion of reinforcement rods, domestic cavities are formed, which dramatically reduce the strength qualities of the foundation, in the end to the rolling of large fragments of the reinforced concrete structure.
• Penetrating into large and small cracks or even simply absorbed in the pores of the moisture concrete has a powerful destructive effect, which manifests itself during freezing. By repeatedly increasing in the volume when switching to a solid aggregate state, water can literally break into parts seemingly powerful, invulnerable to external influence of concrete structures or wall-laid walls.

• Finally, in the presence of a rigor or closely arranged aquifers, it is impossible to exclude and waste exposure. The constant dynamic contact of the foundation structures, even with absolutely clean water, leads with superficial disorders - washed with sinks or cavities, which are then becoming centers of foci of the erosion of concrete and corrosion of the reinforcing frame.

So, the arguments for the conduct of high-quality waterproofing works are more than enough. Now let's see what ways you can do it.

What are made to protect the foundation from the destructive impact of moisture?

To prevent the devastating effects of soil and atmospheric moisture on the construction of the foundation, a number of measures are being taken. These include the following:

• Materials, the basis of the building is presented, additional hydrophobic qualities are attached.
• On the walls of the foundation, vertical (over their entire height) and horizontal, impenetrable coating moisture are created.
• Claiming horizontal waterproofing between the foundation and the walls are based on its basis - to prevent the capillary spread of moisture up through the wall material.
• Provided by creating drainage and storm sewage, constant effective removal of excessive moisture from the foundation of the house.
• Measures are being taken on thermal insulation of the foundation design and the band of the scenes around it.
• The waterproofing and insulating layer itself is provided with reliable protection against mechanical damage.
• For basement or basement floors, effective air ventilation is ensured.

There are several varieties for this area of \u200b\u200bconstruction. Not all of them are equally able to withstand the external pressure of moisture, differences on the technology of application are significant, the difference and price segment may be great.

The table below shows a comparison of some of the main types of waterproofing the foundation by their ability to withstand various types of soil moisture and according to strength parameters.

Probably, one explanation should be made regarding the last columns of the table - classes of basement or basement rooms:

• Under the first class, the premises to which are not subject to special waterproofing requirements are implied. That is, the wet spots on the walls are allowed there, and even small leaks, but completely eliminates the use of any electric lighting and outlets. Naturally, in the residential construction of hunters, it is not found such a room.
• The second class is the utility or technical rooms, with a thickness of the walls of at least 200 mm, where wet evaporation is allowed (they should be deleted by the mandatory ventilation system), but the stains of damp should not be. Under such conditions, the room can be equipped with electrical wiring.
• The third class is the optimal standard for a residential building, that is, it is desirable to navigate it for it when independently constructing. The penetration of moisture is completely excluded, the work of natural or forced ventilation is ensured, there are no restrictions on the equipment of the premises. The thickness of the walls is at least 250 mm.
• With the fourth class of premises in which a special microclimate must be ensured and strictly regulated by humidity and temperature indicators, in private construction, as a rule, do not face.

If you analyze the table, and at the same time consider the cost of various materials, one of the most optimal solutions becomes the use of inlet rolled waterproofing on a bitumen basis - it fully corresponds to the class III room, resistant to crack formation and is able to protect the foundation from the impact of any typewater types. . And in order to achieve the best indicator of reliability, it is often combined with improving insulation on a polymer-bitumen basis.

A brief overview of the rolled materials on a bitumen basis

A peculiar standard of quality and efficiency of waterproofing for foundations can serve as the products of the Russian company Tekhnonikol. In its product assortment - a number of rolled materials on a bitumen basis, which are great for these purposes. And they differ in the target destination, the thickness of the created layer, the features of the technology of application on the surface of building structures, durability, and, of course, according to the price criterion. That is, the consumer has the ability to choose the material optimal for its conditions.

The most popular varieties of rolled waterproofing materials of this brand are shown in the table:

As can be seen from the table, the materials differ in the thickness of the layer being created. But what is the thickness should be finished waterproofing? You can focus on the following indicators:

• When working on the foundation of a shallow embezzlement, up to 3 meters of depth, there are enough 2-millimeter waterproofing (naturally, with reliable sealing of all overlap material and creating protection against mechanical damage to the ground). Thus, one can use single-layer installation, but with a mandatory increase in vulnerable places (it will be described below). True, if the economy class material is used, it is better not to suck, but to perform two-layer waterproofing, and with the obligatory displacement of the seams between the sheets, about half the width of the rolled material.
• For the foundations of deep downstream, with a depth of soles from 3 to 5 meters, the thickness of the generated layer should lie in the range from 4 to 8 mm (depending on the specific features of the soil on the construction site).
• And finally, in the case of shut down the sole in the ground below the 5-meter level, the waterproofing should be from 8 mm and more. In private construction, such foundations are usually not resorted, so this information is just for information.

Basic technological rules of waterproofing foundation by rolled bitumen materials

General Foundation Waterproofing Schemes

Foundation waterproofing is divided into horizontal and vertical. The schemes below will show the typical location of such waterproofing layers on the foundations of two types - on and on the monolithic plate.

On the selected and carefully compacted soil (pos. 1), a sand-gravel pillow is embanked (pos.2). In addition, the so-called concrete preparation (pos. 2) can be conducted on top of it (pos. 2) - the layer of about 50 mm thick of the skinny concrete is poured, which will be the basis for further fill or laying the foundation tape.

The monolithic belt foundation is presented in this scheme - the prefigations of its options are often used, but the essence of this changes insignificantly, there are only certain nuances.

Monolithic tape or stove (pos.4), which will perform the role of the sole, and sometimes - also the base of the floor in the basement, as in this illustration, it is necessary to separate from the layer of concrete training "first tier" rolled waterproofing (pos 3) to eliminate the capillary absorption of moisture below. In the shown option, the sole and tape (pos. 5) of the foundation are a monolithic design. But in the event that the tape filling separately begins separately, or it serves as the basis for laying the foundation blocks, then another layer of horizontal waterproofing is usually provided - it is precisely along the upper end of the soles, between it and a ribbon.

The transition from the horizontal plane of the sole to the vertical tape must be made "softened". For this, the transitional cartel is laid out along this inner corner (pos. 6).

Vertical waterproofing on the walls of the foundation tape (pos. 7) is welded or pasted over its entire area into a pre-prepared and treated with primer bituminous primer surface.

The horizontal surface at the top of the foundation tape is also waterproofing at mandatory (pos. 8). This horizontal layer becomes a reliable cut-off from the spread of capillary moisture from the soil to the walls of the future structure. This can be performed by a bend of the provided surplus of rolled vertical insulation, or separately, cut-out ribbons, but with a prerequisite for reliable sealing of the transition from the wall of the tape to its upper end.

The diagram is additionally shown: the pipe of the ring drainage system (pos. 9), the importance of which has already been mentioned above, the backstage of the foundation (pos. 10), which is carried out after the work on its waterproofing and, if required, insulation, and the cesspool around the base Buildings (pos.10).

Never forget about high-quality food!

It does not only detect the decorative function - its importance in ensuring the durability of the basis of the foundation, and therefore the whole building as a whole - it is difficult to overestimate! What are you, and how to build them with your own hands - read in a special publication of our portal.

Now we turn to the waterproofing scheme of the slab basement:

In the dug pit on the rammed soil (pos. 1), sandy (pos.2) is carefully compacted. On top of it, a layer of gravel or crushed stone is spread over and thoroughly (pos. 4), which will also perform a certain waterproofing role - through such a layer, the capillary "suction" of moisture is reduced from the bottom, from the ground. For greater reliability of laid "pillows" produce from peculiar reinforcement, laying a geotextile layer between them, for example, Dornita (pos. 3).

Above is a layer of concrete preparation, a thickness of at least 50 mm (pos.5), which lines the basis and becomes the base for the most important work with the foundation plate. And this layer already needs high-quality horizontal waterproofing (pos. 6), which will become a barrier that fully protects the foundation from moisture below. The optimal solution for this is precisely rolled bitumen-polymeric waterproofing materials that are skylight, hermetically covered concrete training.

In this illustration, a warmed version of the foundation plate is presented. In particular, on top of the waterproofing placed plates of extrusive (pos.7), designed specifically for the insulation of foundations and loaded floors. And only after that the reinforced base plate (pos. 9) of the calculated thickness is poured.

Note - there is another layer of waterproofing between the layer of thermal insulation material and the foundation plate (pos. 8). He has a few other purpose - he only interferes with the exit of moisture and cement milk from a poured concrete solution, thereby providing optimal maturation of concrete to a complete set of vintage strength. Here, to create a waterproofing barrier, it is quite possible to do the most economical material, for example, to use a dense polyethylene film with a thickness of at least 200 microns.

Well, the resulting stove itself is so far only the foundation from which the building walls will also be made, and further equipment of the first or basement floors. In front of any of these operations, another complex of waterproofing works is required - a solid rolled waterproofing, which ultimately covers the entire stove, reliably protecting it from the penetration of moisture from above. In addition, measures are envisaged for the insulation of vertical ends of the slab - as a rule, such measures are already being taken during the insulation and decoration of the base.

It should be noted that these options were shown only for example, and in fact their diversity - extremely large. But the basic rules are always complied:

• The first is to protect the underground part of the foundation in contact with the soil, from the effects of soil moisture.
• The second is to provide a "cut-off" between the foundation itself and any other design of the house, which is built on it.

Technological techniques for laying rolled waterproofing on a bitumen basis

Further, the instruction tables will consider the basic technological methods of performing the foundation waterproofing. Particular attention is paid to complex places that require additional strengthening, and about which, unfortunately, some masters simply forget, or deliberately ignore this issue, thereby growing the overall duration of the process and save material. If work is planned to be carried out independently, but with the involvement of the brigade, then this question must be controlled.

Execution of horizontal waterproofing

Illustration
	As a rule, the waterproofing of the horizontal part of the foundation (with the exception of the top end of the tape) is carried out on concrete preparation. Ideally, it should be carried out before the arrangement of the ribbon foundation soles or to fill the tape. An exemplary scheme for the correct location of the waterproofing layers is shown in the diagram. 1 - concrete preparation; 2 - horizontal waterproofing from rolled materials; 3 - wall of the foundation, monolithic or laid out of blocks; 4 - transitional cartel; 5 - section of waterproofing reinforcement; 6 - Vertical waterproofing of the foundation tape. Note - with this approach, the horizontal waterproofing layer should go beyond the borders of the future ribbon at least 300 mm - the connection between the horizontal and vertical waterproofing will be sealing.
	There is no point in starting work on the unprepared - dirty, dyed, uneven or even unstable surface. It means that the state of the surface should always be conducted by the first step. It should not be cracks, chosel, implications of concrete, unstable areas or material crumbling. When defects are detected, appropriate repair work is carried out. The value of the surface level of the surface should not exceed 5 mm on 2 of the route meter - this is checked by applying the long rule.
	The surface must be purified from any contaminants that may interfere with the normal adhesion of the waterproofing layer with the base. It concerns dirt, oil spots, etc. In obligatory, carefully removes dried cement milk and dust. Large dirt can be shown by a broom ...
	... But it is better to use a powerful construction vacuum cleaner for efficient cleaning from small dust.
	The next step should be the priming of the surface of the primer. However, before proceeding to this operation, it is necessary to make sure that the residual moisture content of concrete by weight does not exceed 4%. The optimal method of conducting a check is the use of a special device-moisture meter. It is clear that such a tool is far from everyone, so you can use the "folk" reception. To do this, a fragment of a polyethylene film is spread on the surface of the concrete, the size of 1000 × 1000 mm, and the perimeter is tightly glued to the base with the help of waterproof construction tape. The next day you need to check: whether the condensate drops appeared on the film.
	If dry film - you can move to the surface priming. For this, a special primer Tekhnonikol No.01 is usually used or "No. 03".
	If the ripening period of concrete training has completely output, but the humidity remains elevated (the traces of condensate on the film are visible), that is, the ability to use the Primer Primer "Tehtoniko No. 04", as it is made on a water basis.
	Before applying, the primer is necessarily mixed. It is better to do this with the help of an electric drill by installing the nozzle-mixer on it. Small speeds should be exhibited on a drill.
	The primer is applied abundantly, evenly, over the entire surface, without leaving the "light" stains. On large areas, it is most convenient for these purposes to use a long pile roller, planted on a long handle.
	For processing complex, hard-to-reach places, it is advisable to use a painting brush with a dense and rigid bristle. It should be noted that the manufacturer does not recommend mechanize the process of primary with certain types of sprayers - quality is guaranteed only when manually applying compositions.
	After coating the entire surface of the primer, it gives it time for full of graze. It is unacceptable to carry out work on the catch of rolled waterproofing for a non-dry surface. Moreover, even within one room or one platform, it is impossible to in parallel to maintain the primary and styling of waterproofing, or even other works associated with open fire (for example, welding). The readiness of the saddened surface is easy to check - for this you only need to press it a conventional napkin. If a black trail remains on the napkin - it's too early to talk about the beginning of the next stage.
	Only after the napkin will not be traces from the primer, it is allowed to move to the laying of the rolled waterproofing material.
	Equipment for moving material is preparing for operation. It includes a cylinder with propane, gas heating, gearbox, connecting hose. Preparation is carried out in strict accordance with the instructions, in compliance with all safety requirements. There should be a good fire extinguisher at the venue. Hands of workers should be protected by reliable mittens, clothing - do not leave open areas of the body.
	Work is advisable to start with fitting the starting sheet of rolled waterproofing. It is deployed on the desired length, if necessary, cut into size. If there is such an opportunity - it is recommended to even give the material for some time in an expanded state. The canvas should be exhibited exactly at the place of which it will be paid - once it is about the starting sheet, then on the edge of the insulated site.
	It is even better if you immediately hold the fitting of several sheets, rolling them, cutting and immediately setting the necessary adhesions over the ends and side parties. The following rules are followed:
	The end fattest of the adjacent webs, located in the same line, should be at least 150 mm.
	The lateral side between the two adjacent strips of the material is not less than 100 mm. In the same case, if only one layer of waterproofing is pasted, this nest is recommended to increase to 120 mm.
	In places where end and side alternates will be intersect, T-shaped seams are obtained. To ensure reliable sealing of such a compound, on the sheet that is in the middle between the upper and lower, the corner with sides of 100 × 100 mm is cut into the diagonal.
	It is necessarily monitored that these T-shaped seams walked with a dispersion - the distance between adjacent one should be at least 500 mm.
	After fitting the sheet of roll material, it is reappeared again - for this, a cardboard sleeve or a cutting of a metal pipe is used. For the convenience of work, you can download the roll is not one way, but from both ends to the center.
	Start a stamp material. For this, the flame of the gas burner is heated by the back side, with a logo applied on it. The heating should be so that the protective film was paid - it will be well noticeable on the deformation of the drawing pattern with the logo. At the same time, the flame burner also warms the concrete base to be waterproofing.
	When heated, the burner is smoothly moved along the width of the roll. And only when the melting is achieved throughout the plot, it makes rolling so that the melted zone fits tightly to the surface. At the same time, each pressed area as rolling will "drive" in front of him the roller of the molten bitumen - it should be, it should be just talking about high-quality catchment.
	On the Internet you can find a lot of illustrations and videos, on which the master produces roll rolls from themselves, pushing it forward to the foot. Meanwhile, it is a violation of technology, and at once for two reasons. First, the employee in such a position cannot fully visually control the correctness and completeness of the proportion of the material of the material. And secondly, moving into the shoes on the softened flame of the membrane, it is completely easy to damage its protective upper coating, which will lead to a decrease in the quality of waterproofing.
	Roll rolling need to be held on itself. To do this, it can use a metal hook, which is easy to make from cropping reinforcement, processing it after bending so that there are no sharp edges on the rod.
	Another option - from the same reinforcement or rigid wire, you can make a loop, the edges of which are harvested from the ends into the sleeve to which the rolled material is wound. To deploy a heated roll with such a device, simply regularly pulling on itself - even easier.
	It is advisable to spend the job with a partner, which immediately after turning the next weaving site will rent it with a massive rink. The rolling is carried out from the center of the canvas to the edges, several diagonally, that is, "tree", so that it is completely eliminating the presence of non-deposited areas and air bubbles. Waves, folds, wrinkles are unacceptable. Special attention is paid to such an operation to sites of end and lateral adhesions.
	After rolling the edge zones from under the deposited sheet, there should be a small, order of 5 ÷ 10 mm, the roller of molten bitumen - it speaks of reliable sealing of the edge. In this order, the work continues until the entire surface is covered with a solid waterproofing layer.
	In some cases (this mainly depends on the hydrological characteristics of the construction site of the foundation) is allowed to install horizontal waterproofing using free laying technology, that is, without stuffing throughout the area. It is resorted to the same method in the case when the waterproofing is not performed on a concrete base, but according to the rammed sandy-gravel "pillow". With a similar approach, the operation of preliminary surface primary falls, the rolls are simply alternately on the surface, and at the same time all the same linear parameters of the adhesive are observed. After an accurate fit of the two wall bands, the edge of the upper cloth is gently lifted by a hook, the edge zone is heated by a gas burner, only the secession of the adhesion is produced. Then this strip is mandatory rolled with a rink. True, when choosing free laying technology, it should be remembered that one layer of roll material does not work out. And at the same time, the second layer should be filmed the same way as described above, that is, throughout its area.
	In any case, when moving the second (and then subsequent, if necessary) the layer direction of the canvas can be deployed 90 degrees. If the direction does not change, then a mandatory displacement of longitudinal seams is performed, at least 300 mm, and optimally - half the width of the sheet, that is, 500 mm. The remaining parameters of the adhesive and the distance between the seams are the same as when mounting the first layer.
	Another important nuance. In the case when a material with specific characteristics (for example, "technolast alpha" or "Technolast Green") is used in multi-layer waterproofing), then it should be located on the side facing the soil. So, when horizontal waterproofing, it becomes the first layer, and then covered on top of another material with standard characteristics. Climbing forward, it is possible to immediately say that with vertical waterproofing, the picture changes to the opposite - first the foundation walls are covered with a conventional material, and insulating with special characteristics is mounted outside the outer layer. On the circuit arrows and numbers show: 1 - enhancement element - from material with standard qualities. 2 - layer of waterproofing from material with standard qualities. 3 - layers of rolled material with specific qualities (Alpha or Green).
	In the case when the production of fireworks is impossible or inappropriate, a self-adhesive version of the rolled waterproofing can be applied. In the Tekhnonikol lineer, it is represented by the undisguised material "Technoelast Barier Bo"
	The process of surface preparation is practically no different. Primer processing is a mandatory operation. The roll is rolled, trying on and then rolls from two sides to the center. Under the fitting and in the course of further work, all the parameters of the overstons remain the same as when the waterproofing is applied.
	The adhesive layer on the bottom of the cloth is covered with a polymer film. It is neatly clipped and fit along the entire width of the roll.
	Then the film is neatly removed, freeing the self-adhesive layer, and start the roll of the roll.
	Work is best done together. One worker, removing the protective film, gradually rolls the roll on himself. The second, moving along the already distilled material, with a wide rigid plastic brush, drives out air bubbles and provides a dense fit of the material to the surface. Since the surface is treated with a primer, a very good adhesive contact with waterproofing is provided.
	All sections of the adoles are additionally rolled in a heavy roller.
	Now - a few words about the horizontal waterproofing of the base part of the foundation (the top end of the tape). It is forbidden to carry out any construction work on the construction of walls until the cut-off from the possible propagation of capillary moisture is below. Work starts, again, with thorough cleaning and dedusting the surface of the tape. Then the primer is prepared for work - the same as in the cases considered above.
	The primer is abundantly applied to a wide paint brush for all surfaces to be waterproofing.
	While the primer will dry, you can prepare for work rolls of waterproofing material. They must be chopped by the width of the foundation tape plus another 50 ÷ 70 mm of battery with each of the sides. Cut the whole roll on the bands of the desired width can not roll it. To do this, you will need an electric logby with a long saw. Gradually turning the roll, make deep cuts on the outlined circumference.
	In the center of the roll, these cuts will be connected, and mini rolls of the same factory length are obtained at the exit, but already with the width of the work required for a particular section.
	The cropped roll is adjusted at the place of the future installation. It rolls, align, so that the material strip does not "run away" from the direction of the foundation ribbon line. Then one edge can be immediately grabbed by moving, thereby fixing the position of the canvas, and roll - roll to this edge.
	By the way, if the amount of work is not so big, and there is no possibility to rent a gas burner with a balloon, then in this case you can use the usual gasoline solder lamp - many in the garages there are such a tool. It will be possible to work, maybe not so convenient, but for the surface of the foundation tape - it is quite normal. But it is better not to calculate on the construction hairdryer - its power will almost certainly be not enough for high-quality propellation of the protective layer of material and for simultaneously warm up the concrete surface.
	Further - almost everything is the same as in previously considered cases. The roll is gradually rolled with a pre-melting of the protective layer of waterproofing. The filtered material is recommended immediately rolling with a hand roller or silicone roller.
	The side adhesions are not foreseen here, and the end is done in the same way - with an imposition of at least 150 mm. And at the points of intersection or adjoining the sides of the foundation tape, the nape can be sent over the entire area of \u200b\u200bthis intersection.
	Speakers on the edges of the ribbon excess material are applied to the vertical wall. If vertical waterproofing has already been performed there, it will be a reliable sealing navel.
	If the waterproofing and insulation of the base are planned to be placed later, then you can leave the outer side of the basement of the foundation of the foundation. Or, even, probably even better, after moving this intake, additionally, apply another band of the material of the required width. After cutting from the roll, this strip is first rolled and leveled.
	And then, just as before, it is produced already on the previously mounted layer of horizontal waterproofing of the tape. In the future, when the base will be isolated, this strip will overlap all the layers, creating a reliable barrier from the penetration of atmospheric moisture and precipitation from above.

Vertical waterproofing foundation

Illustration	Brief description of the operation
	If the waterproofing will be carried out on the foundation just built, then the trench is usually immediately provided for the work. In the same case, when it is required to hydroize the old foundation, you will have to choose a soil along the walls to the entire depth, right up to the sole. Trench width make such that the movement of workers and the safe fulfillment of all technological operations is ensured, and if necessary, the installation of scaffolding, forests or goats is also.
	Work is starting with the cleaning of the surfaces of the sole and the walls of the foundation. It is necessary to carefully consider all the puffed dirt, remove the influx of concrete or masonry solution, repair all the cracks and cracks.
	Invalid failures in the surface, differing from the overall wall plane of more than 5 mm per two route meters. If necessary, the leveling is performed using the repair solution.
	Surface cleaning is carried out first with scrapers (spatulas), then a rigid brush with metal bristle. All fallen dirt dropped down, leaving a clean dust of the sole surface.
	If there are transitions with a horizontal to a vertical surface, for example, from concrete preparation for the sole and from the sole to the wall of the foundation, then the transitional cartel is laid out. It can be mounted from a building solution with a rapid grasp, as it does not perform any kind of carrier function, and serves only for dense fitting of waterproofing in places of a sharp change in direction, smoothing them. Dimensions Quantis are about 100 × 100 mm.
	It is laid out and lines the galler with the help of a trowel or spatula.
	The vertical surface of the foundation with the lined cartoons will look like this.
	After the karts are frozen, and provided that the residual moisture of concrete of the main surfaces of the foundation corresponds to the norm, begin priming the surface to the primer. Humidity norms are the same as specified in the previous table. The primer is thoroughly stirred and is abundantly applied to the surface with a brush or roller on a long handle.
	All hard-to-reach plots, and in particular - internal angles and transitions, are mandatoryly labeled primer with a brush, so that there are no unprocessed areas.
	After complete grazing, the primer is moving to the catch of waterproofing material. This complies with several important rules: The first is all the work from the sole of the foundation towards the ground part, so that each subsequent mounted fragment is fed to the lower.
	The second - each of their focused sheets is also mounted below up. Otherwise, the melted tar will flock down the walls, enter the hands, clothes and shoes of workers, and the quality of the waterproofing itself - will decrease sharply.
	The third - the carved fragment should not change the direction from the vertical on the horizontal and, on the contrary, more than two times (ideally, and one time is enough). That is, there are two or more sheets of material on the "broken" sites.
	Fourth - all complex areas require the creation of a gain. Such can be attributed to the transitions of the horizontal surface to the vertical and vice versa, which is characteristic of the foundations with the sole, as well as all the external and internal vertical angles. If a pipe of engineering communications passes through the wall of the foundation, then additional amplification and sealing is also performed.
	Thus, if you suddenly noticed that the invited masters begin to "sculpt" the rolled material with a solid cloth from the sole to the base, without making any plots of gain, then there is a complete base to drive them away. This is a blatant violation of the installed technology, and the reliability of waterproofing will not be provided. Despite the elasticity of the material, with this approach, it is almost impossible to completely eliminate the creation of air sinuses. And on the listed complex areas, where waterproofing will definitely experience the highest stresses, the material can simply break through with time.
	So, begin with strengthening, and, in particular, from the transition from concrete training on the base of the foundation.
	A fragment is cut out, with such a calculation so that its length does not exceed 1000 mm, and at each of the planes of the enhanced section found at least 100 mm of the material of the material. The recess of adjacent strengthening bands of one level is at least 100 mm. By the way, this rule is observed at all parts of the amplification.
	The carved fragment is folded into the roll and applied to the intended site. Pressure starts to lead from the transitional cartel.
	Then the upper part of the vertical wall is applied.
	After that - the bottom, for which it is neatly coming and lifted by the crochet.
	The glued fragment necessarily hires a manual silicone roller throughout its area to ensure its dense fit to the surface, without air cavities.
	A peculiar "indicator" of the quality of the sticker will be served throughout the perimeter roller from the molten bitumen.
	The next plot of amplification is the transition from the vertical wall of the sole to its horizontal part.
	The rules here are the same, the technology of the intake also has no features
	The next reinforcement belt is in the transition strip from the sole on the wall of the foundation, through the transitional cartel.
	The order of work and the rule is exactly the same as on the reinforcement belt when moving from concrete preparation for the sole.
	All horizontal reinforcement belts are not adjusted to external or internal angles about one standard strip, as they should lie on top of the amplification of the angles. Transfer to external vertical corners. They are enhanced by several fragments. To begin with, the "heel" is cut, which is cut from above and below, as shown in the illustration.
	After moving and smoothing, it will look like this.
	Next, cut the strip, which will completely close the vertical butt two planes. From above and from below is a battery of 100 mm, which is caught in the center.
	Initially, the vertical site will be filmed, on both sides of the angle.
	Then the lower "petals" are pasted, which will disperse on the sides ...
	... And then the upper - they, on the contrary, will fall with overlay one to another.
	As a result, after catching, this gain will look like this.
	Such an operation is carried out at the outer corner on the section of the transition from the sole to the vertical wall of the foundation. The difference can only be that the upper edge is sometimes not started on the horizontal surface of the tape, and breaks on the planned height.
	After the missing bands of the horizontal levels of amplification lie here, the outer angle will take a finished look.
	Now the problem of internal angles. To begin with, this fragment-heel is cut out, which will be filled in the area of \u200b\u200bthe quilt with the transition to the horizontal surface.
	The same fragment - after moving into place.
	Then the fragment is cut out, which will block the vertical part of the angle. A corner of "spout" is cut on it to it, which is supersed, and the top should be higher than the level of transition to the horizontal surface by about 100 mm.
	Initially, this fragment is filmed and rolled on the vertical surface, alternately on both planes converging in the corner.
	Then the lower part is pasted carefully, with a mutual imposition of cropped corners.
	After that, the protruding edge along the corner line is not covered. The resulting "wings" will be filmed on a horizontal surface.
	The surveillance between them is overlapped by a "heel" by the patch.
	After the reinforcement, the top of the enhanced inner corner will look like this ...
	... and the lower tip of the node is like this. The inner angle in the field of transition from the sole to the foundation is carried out in a similar way. Again, the difference happens that the waterproofing layer may not reach the very top of the foundation tape.
	Transfer to the catch of the main areas of waterproofing. At the same time begin to bottom, so that the first fragment begins on concrete preparation and ended on the horizontal plane of the sole, along the transitional cartel line.
	Pointing start from the bottom line of the foundation plate and lead up.
	After that, the hook is lifting the remaining lower plot on concrete preparation - and weld it. As a result, this "picture" should turn out. The work continues in the same order throughout the perimeter of the foundation, providing regional beetles of 100 mm. In this case, it is necessary to ensure that the dispersion between the seams of the amplification and waterproofing belts was at least 300 mm.
	For docking on the outer corners, sheets are cut through the corner line, and from the bottom - diagonally.
	External angle after moving the first waterproofing layer.
	In the inner corner, it is also used to cut down diagonally.
	The inner corner after docking two waterproofing canvases.
	The remaining lumen between the canvases is closed by a filtered pop-stock, which is kept in the recommended sizes.
	After the installation of the lower belt of vertical waterproofing is completed, go to the laying of material on the main surface of the foundation walls. Fragments are cut into the desired length, but taking into account the rule - with a manual filing of the roll, its length should not exceed two meters. With a mechanized feed - you can use the rolls entirely.
	The lower edge of the canvase must overlap the edge of the mounted lower tier by 150 mm, and the displacement of the vertical seams is at least 300 mm.
	Initially, the roll will be filtered from the cartoons up ...
	... and then the remaining lower part of it is applied.
	If there is a need to use several fragments in one vertical series, then the end alllest should be at least 150 mm.
	When the neighboring vertical series is filmed, take into account the rule that the disintegration of end adhesive on the vertical surface cannot be less than 500 mm.
	The work is carried out in the same way until it covers the walls of the foundation to the top, with a possible occasion of the horizontal plane of the tape and its overlapping, or to a specified level. At the same time, it is taken into account that the upper edge of waterproofing on the base cannot be below 300 ÷ 500 mm from the surface of the soil.
	If necessary, they perform the second and even the third solid layer of waterproofing, again, starting from the surface of concrete preparation. At the same time, they are guided by the rules already listed and similar scheme - each subsequent layer overlaps its edge overlap. In addition, before the filming of each next layer, the external and internal angles are again carried out - according to the principle shown above.
	In the event that the mounted waterproofing ends on the surface of the base, its edge must be additionally fixed and sealing. To do this, the edge is pressed against the surface of the base with a special profile rail with a dowel.
	A deformation gap of about 5 ÷ 10 mm is necessarily left between adjacent rivers.
	The same clearance must be observed at any angles. The dowel installation step is 100 mm between the first and second from the corner or the edge of the rail, and then it is 200 mm. At the same time, the extreme dowel should settle down not closer than 30 ÷ 50 mm from the angle.
	The top of the profile clamping rail has a bent outstand. This lumen is tightly filled with a special polyurethane sealant "Tehtonikol No. 70".
	The sealant is superimposed by a solid strip, including on the plots of the clamping rail. On this, the vertical waterproofing of the foundation by rolled materials can be considered in principle completed.
	But the waterproofing layer still needs to protect against mechanical damage during the inverse swelling of the soil. If the foundation is not assumed, then efficient protection can be performed using a special profiled "PLANTER STADARD" type membrane. She, by the way, will also become one additional barrier from moisture penetration.
	The membrane is covered with the surface of the outer walls of the foundation, having it spikes to the wall and fastened from above with a dowel with wide hats. It is important - any mechanical mounting with the drilling of the holes in the wall is allowed solely above the ground line of the soil, since it is strictly prohibited below the waterproofing.
	Additionally, in height, the membrane is conveniently fixed with special fasteners, which have a leg with a self-adhesive base and are perfectly held on the surface of waterproofing.
	Then these locks are simply pushing the membrane while holding it in the specified position.
	Rules of installation and docking MEMBRANT MEMBRANES: - The upper edge should be higher than the weld waterproofing approximately 300 mm.
	- The recess of neighboring webs - minimum four spikes.
	- and external, and internal angles should be closed with solid stripes, with such a calculation so that at least 1000 mm width accounted for each side.
	- Membranes jokes, to avoid the soil from entering them during the backfill, are sampled by the strips of the sealant tape. Sticking produce from top to bottom, gradually removing the substrate closing the adhesive layer.
	- And finally, the top edge of the profile membrane is advisable to fix the special clamping profile. The rules for its installation are similar to the fact that they were considered higher for the profile fixing the waterproofing.
	So after that, you can already feel free to switch to the backup, conducting a thorough layer-by-layer grinding.

In the same case, if the foundation requires insulation (and this event is always highly recommended!), The role of protecting waterproofing from mechanical damage will take on a layer of extruded polystyrene foam. But this is already the topic for separate consideration.

The insulation of the foundation is a deposit and its durability, and comfort in the house!

It would seem that a unnecessary occupation - because the foundation directly does not contact the residential premises. However, the importance of quality is extremely great! More about this - in a special publication of our portal.

At the end of the publication - a video of the waterproofing of the foundation by rolled materials, which can also behave with the independent implementation of this stage of construction of the house.

Video: Waterproofing of the foundation by roll materials "Tehtonikol" - video structure

The waterproofing of the foundation is the most important operation when erecting the founding of a private house. Only correctly performed by the protection against moisture will allow for a long time to preserve this element of the structure. You can make this work in various ways, but the most simple to use is the waterproofing of the foundation by rolled materials.

The foundation, as a rule, is poured by a concrete mixture. This material has quite high hygroscopicity. If you do not make waterproofing, then various microorganisms begin to multiply in the crude. If the moisture affects the foundation of the building for a long time, there may be cracks and skews, which will also negatively affect the geometry of the walls.

If the house project is provided for a basement or ground floor, the absence of waterproofing foundation will manifest itself with such negative phenomena as the presence of mold, dampness and heights on the walls. If the level of groundwater, where the building is raised, high enough, the moisture can be penetrated into the room and accumulate on the floor, which will make it impossible to use it for its intended purpose.

Even in the southern regions of the country and low-water, the waterproofing of the foundation should be carried out at mandatory. For example, a spring flood is enough for several days to apply the foundation of the building irreparable damage.

Among the main advantages of this technological operation can be called:

• Strengthen design.
• The amount of maintenance of the foundation and walls is reduced.
• Makes it possible to operate basement and basement.

Regardless of the type of foundation, waterproofing is necessary to extend the "life" of such a design. Special rolled materials are ideal for this purpose.

Types of rolled waterproofing

For the waterproofing of the foundation, materials of various species can be used, for example:

• Powered.
• Clause.
• Diffusion membrane.

Equal rolled waterproofing is a bitumen-polymer composition. Such material is distinguished by a high degree of protection against moisture penetration, durability and simplicity of installation. The cost of inheritance waterproofing is also small. This material can be used not only for the waterproofing of the foundation, but when open-air installation, such products can be collapsed under the influence of precipitation and ultraviolet radiation.

The weld waterproofing is also available in the form of rolls, but for its installation it is not without a burner. This tool is necessary for softening the material. As a result of the melting, the waterproofing sheets are reliably soldered among themselves, thereby preventing moisture penetration to the protected surface.

Diffuse rolled waterproofing is a modern material that does not only reliably protect the foundation, but also contributes to the moisture disposal from the room. The only disadvantage of the diffuse membrane is the price, but if the waterproofing is done in its own home, it is not necessary to save.

Popular manufacturers

Rolled waterproofing materials for foundation can be made by various firms. The most popular on the Russian market are products manufactured under the following brands:

• Ikopal ultra - bituminous polymer material made on a nonwoven-based basis. The base of the waterproofer is high-strength polyester, which is able to withstand very large loads. A feature of this material is the possibility of fastening with a catch or mechanical way. Ikopal Ultra is reliable and durable material, resistant to the effects of adverse operating conditions, therefore, it can be successfully used for waterproofing the foundation.
• Technonol - is the leader of the domestic market of waterproofing materials. The instruction of the rolled waterproofing of the foundation TechnoNIKOL is as follows: The waterproofing membrane from the RBM, intended for the protection of underground concrete structures, is used for laying above the level of groundwater. Under this brand also produces rolled waterproofing self-adhesive, which can be installed without the use of gas burners.
• Hydroizol HCP – waterproofing material based on glass cholester, which we have increased mechanical strength.

All listed brands can be applied to independent waterproofing of the foundation, but before starting to the installation, it is necessary to carefully prepare the surface.

Surface preparation

The preparation of the surface is one of the most responsible stages of installation of waterproofing.

If at this stage, make serious mistakes, then even the use of quality material will not save the situation. After the first months of operation, the waterproofing layer will start separated from the main surface.

To ensure the necessary surface preparation level, four methods are used:

1. Mechanical.

For alignment of the surface, perforators, sandblasting plants, jackhammers are used. Manual tool can also be used.

1. Hydraulic.

To use this method, you will need to purchase or rent a water jetty, which sprays a fluid under pressure of at least 180 atmospheres.

1. Thermal.

Preparation of the surface is carried out using propane or acetylene burners.

1. Chemical.

Salt or phosphoric acid is used to prepare the surface.

When preparatory work is completed, a number of studies and inspections must be carried out before installing the waterproofing material to make sure that the surface meets the following requirements:

• Lack of easily separable elements.
• Lack of cracks, chips and shells.
• Deviation in flatness surface should not exceed 5 mm by 2 meters.
• Lack of dust and other contaminants.
• The humidity of the surface is not more than 4%.

After leveling and cleaning the surface, the priming is proceeded. This operation is performed in order to provide increased adhesion of waterproofing material. To increase the "chain" of the base applies a bitumen primer.

If the moisture content of the basement concrete failed to normalize, the primer technological primer, designed specifically for such cases, should be used. This tool can be used under the percentage of water, in a solid material, up to 8 units. In order to learn the moisture of concrete, a special device is used - a vlogometer.

The application of primer should be carried out with the help of a brush, even with large volumes of work. For this purpose, a tool of various widths can be used. For the processing of internal angles, only small brushes with soft bristles should be applied.

After the surface is covered with a primer and the composition will completely freeze, it is possible to proceed to the direct installation of rolled waterproofing.

Rolled bitumen-polymeric materials are quite simple to lay, but depending on the installation method, you must adhere to the recommendations for a particular method.

Vertical

Vertical waterproofing of the foundation by rolled materials is carried out in such a sequence:

• To wind the required amount of waterproofing material on the pipe or spit from cardboard.
• Gas burner heat the lower part of the foundation and gradually moving up to carry out the installation of material throughout the height.
• With this method of applying the material, the edge inlet should be at least 100 mm.
• Further, the material is stacked in the same way with a false leaf on the previous layer of 150 mm.

The vertical installation of waterproofing material is completed at the place of the end trap.

Horizontal

The horizontal method of laying rolled hydrogenation with their own hands is slightly different from the above version.

• Before carrying out installation work, the material must be deployed over the entire surface and give it a little spitred.
• The material also is placed on the base molten with a bitumen burner.
• Subsequent layers are installed with 150 mm.

When carrying out installation work, it is also necessary to ensure the dissemination of end seams of at least 500 mm.

Membrane

Waterproofing the foundation plate with rolled membrane type materials can be carried out without preliminary surface prime. Laying of such a material is carried out in such a sequence:

• The material is strips along the entire length of the foundation.
• Related sections are melted among themselves.
• For more reliable mounting of the membrane, it is fixed with special screws.

When laying membrane waterproofing, it is also necessary to provide an increment between the layers and the disintegration of the end seams.

Claimed

The weld waterproofing is most often used for roof processing. To protect the foundation, such material can be used quite effectively. Works are performed on the installation of this type of hydrozolation as follows:

• Carefully processed and the base is prepared.
• Bituminous primer is applied to the surface.

• The material is wound on the spool or cut into pieces.
• Using the propane burner, the material is heated in the place of contact with the treated surface.

Thus covered by the protective layer the future base of the house. If necessary, you can put the material under the foundation plate, but this operation will be required to directly install this item.

Ikopal ultrap - multilayer bitumen-polymer rolled material. A binding from a CSP modified bitumen is based on a reinforcing polyester nonwoven fiber. The bottom layer is an elbow polymer film that simplifies the installation of the waterproofing canvas. From above quartz fine-grained sprinkle. Along the edge of the upper and lower part there is a polyethylene film that prevents the injection of the material.

Ikopal Ultranap is used for waterproofing underground and blubble structures of various purposes, external isolation of wells, hydraulic structures, storm sewage, foundations, including fine-brewed belts, etc. Protects the structure at different depth of groundwater, prevents capillary moisture. It can be successfully used in a complex with coating waterproofing.

Structure of material

Bituminous polymer membrane Ikopal Ultranap is suitable for use in all climatic zones of Russia. The service life exceeds 30 years.

Preparation of the insulated surface and rolled waterproofing

The surface on which the material will be laid, it is necessary to clean from garbage, dust, soil, make sure that it is smooth and good. If there are cracks, potholes and other irregularities, then they need to be treated. You also need to eliminate the protruding parts, for example, the reinforcement frame.

Note! Installation of bitumen-polymeric materials Ikopal Ultranap in open areas cannot be carried out at any atmospheric precipitation.

When installing waterproofing method, it is important to remove all pollution from the insulated surface of the foundation (for example, oil spots, cement milk). To do this, you can use sandblasting, after which the dust is needed from the surface.

Before starting work, the polymer membrane must be rolled out and give it to be searched for several hours for alignment. Also remove the protective anti-adhesive polyethylene film from the rolled material. For high-quality installation before working in the cold season, the membrane must be pre-kept at a temperature of about 15 ° C for days and rewind.

Waterproofing with rolled materials Ikopal Ultranap in the underground part of the buildings is carried out:

1. The method of free laying.
2. By moving.
3. Combination of free laying and staining.

Waterproofing by free laying method

Council. When installing the free laying method on the foundation plate, it is recommended to pre-lay a layer of geotextile canvas with a surface density of 300 g / m². Geotextile laid with the adoption of 100 cm over all edges. On the vertical surfaces, the upper edge is mechanically fixed.

To mount the free laying method, you will need:

1. Hot air welding apparatus or gas burner - for welding seams.
2. The crooked machine - for the processing of the seams of the longitudinal adolescence.
3. A roller roller - for the processing of seams of the end adhesion.

Procedure for carrying out work on horizontal surfaces:

1. To put the membrane with the allen 10 cm. The jokes in length should be with a displacement of the adjacent rollers per 1 m.
2. Make welding of seams with a gas burner or hot air welding machine, then roll them.
3. For seams of seams from above, it is recommended to refer to the Bandage tape of Ikopal and also to roll it.

Procedure for carrying out works on vertical surfaces:

1. Waterproofing sequential rows to launch upwards, vertically rolling the cloth. Fall on the edge of 10 cm cloths.
2. At a distance of 5 cm from the upper edge, the rolled bitumen-polymer membrane mechanically fasten the metal strip with dimensions of 4 x 40 x 600 mm. Strip secure self-pressing or dowel-nails in a step of up to 25 cm.
3. Cutting welding with gas burner or hot air welding machine, bottom up, rolling roller.
4. The next row of a row of waterproofing canvas mounted with an adhesive 20 cm on the previous one. Displays neighboring rows of the web so that there are no cruciform joints.
5. If the cloth is placed on a vertical surface above 3.5 m, it must be additionally fixed with metal stripes and self-strokes (dowel-nails) every 3-3.5 m.
6. To eliminate leaks on the mounting metal strips, glue a bandage tape with an adhesive of 10 cm, rolling it with a roller.
7. For the sealing of the seams on them, they also catch a bandage tape, rolling it with a roller as needed.
8. Secure the material above the ground level on the wall of the building with metal stripes and screws (dowel-nails). On the metal strip with the allen on the wall, glue a bandage tape to prevent moisture penetration. Ride the roller.

The bitumen-polymer membrane can also be stacked by a free method for additional waterproofing of the scene. The membrane falls asleep crushed stone and a sandy pillow, which then stacked any coating.

Performance by the method of smearing

Council. Before moving the rolled material, ultrap on an insulated surface is recommended to apply primer. Pressure you need to start after it is complete drying.

When moving rolled waterproofing for the foundation you will need a gas burner.

Procedure for conducting work:

1. Silt the cloth with the allen 10 cm. The joints along the length of the rolled material should go to the rotor with the displacement of neighboring rolls per 1 m.
2. Sing the second layer is similar to the first, with the displacement of the fallen relative seams of the first layer.
3. When mounting on the vertical surfaces, spend the bottom up, excluding cross-shakes. If necessary, fix the waterproofing canvas with metal stripes and screws (dowel-nails). To seal metal bands, glue on them a bandage tape with the allen 10 cm.
4. Secure the material above the ground level on the wall of the building by the edge rail or metal stripes and self-drawing (dowel-nails).

Note! With the correct removal of rolled waterproofing (or when welding seams), 5-10 mm along the edge of the web should evenly extort the bitumen mass.

Waterproofing underground part of buildings and structures

Depending on the specifics of the device of the fence, the underground part of the buildings and structures can be waterproolated by the method of free laying of a bitumen-polymer membrane:

• With the fastening to the walls of the building - to create a hydrocker, if the wall does not adjoin the fitting design of the pit, as well as in the pitchers with slopes with a slope.
• With fastening to the enclosing structure - if the wall adjoins the enclosing design of the pit.

Roll waterproofing TechnoNIKOL for foundation is a non-free bitumen polymeric material. From above, waterproofing is protected by a polymer film, from below - anti-adhesion. With this material, protect against moisture of buildings of buildings with non-exploitable rooms or technical floor, in sandy soils with a reduced groundwater level. In conventional flashing, bituminous waterproofing allocates combustion products. But with the material Tekhnonikol for the foundation it is possible to work even in closed rooms due to the self-adhesive side: fireworks or gluing mastics are not needed.

With this material also buy rolled waterproofing of Paul Technonol to create inter-storey waterproofing.

Benefits:

• self-adhesive;


• placed in one layer;


• has a long service life;


• quickly mounted;


• absolutely waterproof;


• it has a thick protective film that prevents the sticking of the material in the roll.

Packaging and storage

Roll waterproofing TechnoNIKOL for the foundation sold in our online store at a bargain price is implemented in rolls packed in a cardboard factory box. Store products follow one row in a closed storage room or under a canopy. When stored, the material should be protected from the effects of moisture, the sun and store away from heat sources. Permissible storage temperature from -35 to + 35 ° C.

Waterproofing works are carried out for each element of the house under construction. Isolate from moisture. The base of the house, walls and ground floor, basements and floors in the rooms, roofing. This uses a wide variety of various materials for insulation from water or steam.

Wide distribution received waterproofing the foundation by rolled materials. After all, products are inexpensive, simple when laying and durable. In addition, it is possible to work with such an insulator alone, which allows you to save money.

For isolation from moisture of the base of the structure, waterproofing rolled materials are most suitable. In the modern world, products of various quality are produced, which are divided into such a principle:

1. Methods of fastening to the surface.
2. Forms and material manufacturing.
3. Lifecycle and cost ..

To understand the abundance of a roll view insulators, you should know their features and additional parameters.

Based on the fastening methods, waterproofing rolled materials are divided into:

• mechanical;
• applied;
• glued.

Mechanical insulators from moisture is the most inexpensive. But it is pretty hard to work with them. After all, the fastening of products in the process of waterproofing occurs by feeding to the surface. And this is quite problematic and presents additional difficulties.

Claimed products are used most often due to the simplicity of work and relative cheapness. In order to lay such a material, it is enough to simply warm it up before rolling over an insulated surface.

The placed materials also received deserved glory. But here is the cost of them above average. But the quality of work is excellent and the durability is good.

According to the composition, materials differ on:

• polyethylene films;
• bitumen;
• soft membranes.

Horizontal waterproofing

For foundations, such rolled regteroids, bitumen and containing and bitumen polymer insulators are most often used. They are characterized by high strength to mechanical effects, in contrast to polyethylene film, which is also used for waterproofing. Sometimes membranes are used, which perfectly perform the functions of waterproofing, but it is much more expensive than the other materials.

Works on laying the foundation with horizontal insulation from moisture are performed according to such a scheme:

1. Digging trenches, pit, pitted under the foundation of the building.
2. Performing a pillow with a subsequent rambling.
3. Installation of formwork and pouring with a thin layer of solution.
4. Laying materials on the prepared level surface of the trench, pit or pit.
5. Pouring with a thin layer of solution for extra fasteners.
6. Reinforcement.
7. Full fill of the foundation.
8. Secondary waterproofing after the primer of the foundation surface.

Primary waterproofing is stacked on a flat horizontal surface of a frozen solution, which covers the pillow with a thin layer. The formwork is installed immediately before the fill before the first layer of waterproofing is performed.

Rolled materials are folded in a double layer and fit so that some material remains on the walls of the trench. This will allow waterproofing the base of the foundation as impressive as possible.

The same procedure is repeated with the second outer layer separating the base and walls.

Vertical waterproofing

For isolation from moisture of vertical type, rolled products are used or amplified. It is easier to use the materials in the work. But then, before laying waterproofing on the walls of the foundation, the concrete surface should be primed and wrapped with a special adhesive composition. Such insulators are superimposed in several layers.

Works on vertical waterproofing are performed in this order:

• the wall of the base from small garbage is cleared;
• the surface to remove irregularities is ground;
• the adhesive composition is applied not the place of fastening of waterproofing items;
• rolled products are attached to the walls of the foundation;
• uniformly pressed through a special wide roller;
• the backflow is performed by the soil.

Materials that are consistent should first cut into certain pieces, in length coinciding with the height of the foundation. Each piece is heated and applied onto the wall of the base, clinging tightly for strength.

In this case, the insulator is necessary to impose a mustache so that the margin makes about 20 cm. And the waterproofing layer must be double. But the seams are better to arrange in a chess order.

Parameters affecting the choice of roll materials

When choosing materials for waterproofing the base of the house, it is worth considering some parameters:

1. The type of soil on which the building will be built.
2. Depth of soil freezing, which means the depth of the foundation itself.
3. The proximity of the location of the groundwater and their number.
4. The mass of the building itself and its characteristics of operation.

From these factors, it is necessary to come, choosing a variant of rolled products for waterproofing.

So, a deep foundation is to isolate with rolled products based on bitumens with abrasive powders. This will provide a greater durability of the foundation on moving soils during bent.

And for finely swallowed bases on soils with low mobility, it is possible to be waterproofing with polyethylene or PVC film. Economically, high quality and fast. True, for vertical waterproofing it is worth taking stacked rolled products. They are more simple in work, as they have increased strength, unlike films.

It is important to remember that rolled materials are better to store in a dry dark place.

Do not forget that the film is afraid of direct sunlight and loses its properties. But perfectly performs its functions, protecting the sole of the foundation.
