The worst thing for a car is the rust arising from exposure to an aggressive environment. Moreover, it is not precipitation that brings more harm, but the dampness of the closed space of the room.
Careless attitude to the arrangement of the waterproofing barrier leads not only to damage to the stored property, but also to the gradual deterioration and destruction of the structure as a whole. Modular garages made of rolled metal are not without such a problem.
Garage waterproofing is used to prevent moisture ingress, the formation of harmful microflora and general protection of the structure during operation. The focus is on protecting the foundation and, if available, the basement of the garage.
Moisture protection methods
There are two versions of the waterproofing barrier:
- horizontal;
- vertical.
Horizontal
Horizontal insulation is used to protect the foundation and flat roof. If the building is not equipped with a basement, then such a barrier will be sufficient. It is carried out along the entire perimeter of the base with the expectation that the upper cut protrudes to a height of about 20 cm above the zero mark.
Most often these are two layers of roofing material glued with heated bitumen.
The layer is needed so that the lower edge of the wall is not saturated with moisture from the soil.
Vertical
Garages equipped with a cellar or inspection pit require more serious protection. Along with horizontal waterproofing, vertical waterproofing is also performed.
It involves processing the outer part of the foundation along the entire height and the lower part of the wall.
Material base for waterproofing
The building materials market offers a wide range of materials suitable for moisture protection. They are divided into three groups:
- roll (hydro-barriers, vapor barriers, roofing material, tape seals);
- gel-like (mastic, sealant);
- hydrophobic mixtures;
- paint and varnish composites based on polymer compounds.
Most often they are used to treat external surfaces, but they are also allowed for use from the inside.
In practice, combinations of materials from different groups are used to achieve the best effect and compensate for the disadvantages of pure application.
So, during installation, roll insulation forms joints that require sealing. Gel composites are difficult to apply to large surfaces and difficult to achieve even distribution over the layer. Mixtures are more suitable for additional protection of the garage from the inside.
Bitumen and tar have a melting point of the order of 150–170 ° C, which necessitates the use of a metal tank or other suitable container for heating. When working with composites, you need to be extremely careful using personal protective equipment and overalls.
Process technology
The choice of material and method of installation should take into account the presence of a cellar, the type and condition of the soil, the manifestation and level of groundwater, the climate of the area.
It is important to observe the installation stages and adhere to the rules for working with materials to obtain a stable waterproofing effect.
Waterproofing the base of the garage
The foundation must be treated with waterproofing materials before the walls are erected.
It is necessary to clearly understand the condition of the soil and the depth of the groundwater. They are most closely located in areas of natural reservoirs. This should be taken into account when choosing a construction site.
When there is no basement
The moisture protection of a building without a basement and the presence of groundwater is reduced to gluing roofing material to the upper cut protruding above the ground of the base. And the walls, both from the outside and from the inside, are covered with mastic or plastered with a moisture-resistant mixture.
When there is a basement
If the erected garage has a basement, and underground waters are deep or absent in this area, then the floor treatment with a hydro-resistant solution must be added to the horizontal insulation. The screed is mounted on well-tamped soil, covered with an overlap with oiled roofing material.
Under the foundation blocks, it is worth making a base of crushed stone up to 10 cm high and strengthening it by filling it with heated bitumen or resin. Two layers of bituminous mastic or resin are applied to the surface of the blocks at intervals of 3 - 4 hours for better adhesion.
The presence of a cellar and the proximity of groundwater obliges the owner to organize waterproofing of the base of the garage in the form of an integral shell. The process of installing the water protection begins with the preparation of the foundation (the bottom of the pit). Next, arrange a concrete blind area and remove the plane with a cement screed.
Mounting
After the cement has completely dried, the floor is covered with rolled isomaterial in at least two layers. Particular attention should be paid to the gluing of the overlapping strips. The overlap must be at least 10 cm and properly treated with bitumen or resin. The strips of roofing material from the inside are glued to the previously laid roofing material under the lower blocks of the base of the garage. The result is a solid surface protruding up to 30 cm beyond the walls.
The next step is to glue strips of insulating material to the outside of the blocks before joining the horizontal waterproofing. The resulting surface is fused with the edges of the roofing material protruding from under the base. The result is a solid two-layer bowl-shaped hydro-barrier.
In order to avoid mechanical damage to the moisture-proof coating, a screed is made.
From the inside, interblock joints are processed with bitumen mastic, and the surface is plastered to cover with hot bitumen or resin. When using biostable composites based on bitumen for the treatment of internal surfaces, there is a decrease in the formation of rot in stored vegetables.
All work on pasting and applying gel-like insulating materials must be performed on prepared surfaces (cleaned of dirt, leveled, primed). The technology of arranging an inspection pit in the absence of a basement is carried out in a similar way.
Protection of the floor from the effects of moisture is carried out by laying strips of roofing material, glued together at the places of overlap, on a tamped base made of crushed stone or mine workings before pouring with concrete.
If there is a viewing hole, it is worth connecting the edges of the insulating substrate with its moisture-proof coating. Waterproofing the floor in a garage with closely approaching groundwater is enhanced by impregnating the rammed base with bitumen or resin until a monolithic layer is formed.
Protection of load-bearing structures
The garage walls are protected by penetrating waterproofing. It is characterized by the preparation of a solid solution based on a dry hydrophobic mixture and water. The resulting suspension is mixed well and applied to the surface of the wall and ceiling.
To increase the adhesion of the solution to the treated plane, it is moistened. Under such conditions, the coating penetrates well into the porous structure of the plastered surface, forming a reliable hydro-barrier. From the inside, the walls are leveled with ordinary building mixtures.
Garage roofing
Insulating material is selected based on the roof structure. Most garages have a flat slab that is covered with strips of roofing material fixed with hot resin or with a special adhesive on one side. During installation, overlaps are carefully glued, and after the end, the roof is poured with a layer of resin.
In garage cooperatives, you can face the problem of water leakage at the junction of adjacent roofs. The best option would be to jointly carry out roofing works with the creation of a continuous hydro-barrier.
For sloping roofs, the insulating material is fixed to the rafters, and logs and roof sheets are attached from above. In order not to drip from the ceiling, carefully mount the hydro and vapor protection substrate. It should be located up with the side that does not allow moisture to pass through, but is permeable to air.
High humidity and temperature changes contribute to the formation of mold and mildew, the formation of foci of corrosion, and the rise of groundwater in the season harms your motorhome. Correctly made waterproofing of the floor in the garage - this is what will help prevent unwanted consequences, as well as extend the life of your car.
Concrete floors, like other types of flooring, need additional protection from moisture. Concrete, as a material, has some water permeability, and with prolonged exposure to moisture, it is subject to destruction, and gaps between the wall and the floor can cause a number of serious problems.
Floor waterproofing can prevent the risk of such unpleasant surprises as:
- premature destruction of the concrete pavement;
- the formation of leaks;
- erosion of the foundation;
- mold and mildew formation;
- corrosion of metal structures;
- deformation of internal elements in high humidity conditions.
If there is a cellar or a viewing pit in the garage, it is advisable to start carrying out these works with them.
Do-it-yourself waterproofing of the pit in the garage will allow you to protect the basement from various leaks and groundwater ingress there.
In addition, a garage with a basement also needs vertical waterproofing.
Waterproofing the garage from the inside is carried out using bitumen mastic and roofing material. For waterproofing floors, materials such as hot bitumen and gasoline are often used. The durability of these materials from 10 before 15 years.
What is garage roof waterproofing for?
Waterproofing the roof of the garage is one of the key points to prevent moisture from entering it.
One of the most popular types of roof waterproofing is laying roofing material. This coating is ideal for both flat and pitched roofs.
Various types of mastics are capable of providing a continuous coating, but can only be used on a flat roof.
Roofing material and fellows are versatile and can be successfully used for waterproofing any roof.
Roofing material is a dense cardboard, thoroughly impregnated with bitumen (there are varieties based on fiberglass). Euroruberoid, for example, has a polymer build-up layer.
Waterproofing technology with roofing material is divided into several stages:
- The roof area is cleaned, if necessary, the remnants of the previous coating are removed.
It is possible to treat the concrete surface with special agents that increase adhesion.
Rolls of roofing material are unwound and cut into pieces of the desired size with a margin of 15 -25 cm on each side.
- Next, a layer of bituminous mastic is applied, after which, without delay, in order to prevent it from hardening, cooked pieces of roofing material are laid. Here it is necessary to take into account the overlap (at least 10 cm). Thoroughly pass with a roller until the piece is completely glued to the surface.
- The next step is laying the mastic layers.
At the beginning, a second layer of bituminous mastic is applied, after which another layer of roofing material is laid (with an offset by half of the previous strip). Thus, the rest of the cushioning layers.
At the final stage, the roof is checked for blisters and bubbles (if necessary, they are pierced), after which the last layer is also laid on the bitumen mastic layer.
Waterproofing garage walls
“Weeping Walls” is the first sign of a lack of proper waterproofing of the premises. Much also depends on the materials used in the construction of the garage.
Gas blocks, foam blocks and sand-lime bricks are far from the best materials for the construction of a motorhome, as they deteriorate over time, absorbing moisture. Concrete walls are the most suitable option. At the beginning of the waterproofing work, a trench is dug around the perimeter of the garage to the base of the foundation. Regardless of the size of the foundation, waterproofing is always laid above ground level by 20 — 30 cm.
The walls are cleaned of dirt, then cement plaster is applied from the base of the foundation to the bottom of the garage walls. Upon drying, the plaster is processed using bitumen mastic, followed by the laying of roofing material.
With the help of hot bitumen, roofing material is glued in two layers. The protruding edges are glued to the insulation previously laid under the foundation. So, the basement remains completely isolated from moisture. Ventilation installation is seen as an added benefit. If desired, waterproofing the pit and walls in the garage can be done with your own hands.
Floor insulation
Agree, an unpleasant feeling when water begins to penetrate into your cellar in the spring. Waterproofing the inspection pit in the garage is a way out of this situation. First of all, the garage is waterproofed from the inside from groundwater.
Pre-rolls of roofing material should be unrolled and left in this state for at least a day. This simple operation will allow you to avoid swelling of the material in the process of its further gluing.
We make markings in advance in places where waterproofing will be carried out.
The edges of the cut fragments are well coated with bitumen mastic. It will be much more convenient to carry out styling with an assistant.
In the process of laying the roofing material, it is necessary to trace the formation of an overlap between the sheets (at least 1 cm).
Using a roller on the floor in 3- 4 layer, a primer is applied. We give it time to fully absorb.
The joints of the floor, walls and corners can be additionally sealed with sealing tape.
If there are pipes in the room, rubber seals are put on them. The joints are also glued with special tape.
We dilute the bituminous mastic concentrate according to the instructions on the package.
The mastic is applied with a coarse roller; when processing corners and hard-to-reach places, it is best to use a brush.
We pass the walls with mastic to a height 15 — 25 cm.
Let the surface dry completely (this will take at least a day).
Waterproofing the inspection pit in the garage involves a number of works. Fortunately, modern manufacturing companies now provide a wide variety of materials that can help us with this.
For the protection of the recesses, bitumen-based materials in rolls are available. Before starting work, the material should be divided into the necessary fragments and generously lubricated with a special solvent. The finished pieces must be stacked so that the sheets overlap (from 10 -15 Particular attention should be paid to the joints between them. You will need a gas burner to glue them together. The second option for their connection can be pre-prepared fused bitumen. Waterproofing a pit in a garage is not a tricky business and is quite doable with your own hands.
Each owner, purchasing a garage, plans to operate it for a long time and not experience any difficulties with storing cars and tools. In order for the building to cope with the functions assigned to it, it is necessary to take care of waterproofing in advance if this moment was missed during the construction process.
Waterproofing of the garage is especially needed if it has a viewing hole or basement. Dampness and coolness in this case are unacceptable, since no one wants to find tools and spare parts covered with rust over time, especially a car. The process of waterproofing a garage with a basement consists of several stages:
arrangement of the drainage system;
external waterproofing that protects the concrete base, walls and floor from groundwater penetration;
waterproofing the concrete floor in the garage, as well as the interior walls.
The cost of waterproofing a concrete garage floor
As a rule, each building has its own dimensions, therefore, for each case when it is required to waterproof the concrete floor in the garage, the price is formed on an individual basis, taking into account the entire complex of work (dismantling, preparation of the base, repair, the cost of the waterproofing materials used, the amount of work, the complexity of the process).
You can find out the average cost, how much it will cost you to waterproof the garage in the table below, these are the basic prices for services, the specialist will name a more accurate amount after analyzing the premises.
Why waterproof your garage floor?
The concrete floor of the garage needs additional protection from moisture, because this building material has micropores through which ground and melt water seeps, gradually destroying the foundations, causing increased humidity inside the structure, the formation of fungus and mold on the walls. If you do not react in a timely manner, then you can lose the building - after all, moisture will negatively affect the walls of the garage, as a result of which their deformation will begin, metal structures will corrode.
Waterproofing the concrete floor in the garage will avoid groundwater leaks, moisture accumulation, thereby increasing the construction period and preserving the owner's property. Moreover, today there are a large number of technologies on how to reliably protect a building.
Waterproofing a concrete floor in a garage on the ground
Protection of the floor in the garage on the ground is carried out at the stage of construction of the base under the floor, before the screed is poured, otherwise there will be no use from such work. The meaning of this type of waterproofing is to protect the concrete base of the garage from the ground.
As a waterproofing material, PVC films with a thickness of up to 1 mm, laid with an overlap on the walls, can be used.
Waterproofing of a concrete floor over the slab
Waterproofing the concrete floor in the garage above the basement (over the overlap) is done when the floor simultaneously serves as an overlap between floors, and the groundwater is close. In this case, you can also use plastic wrap or use bituminous mastic in combination with roofing felt.
If the waterproofing of the floor was not carried out at the design stage of the building and an inspection pit is planned in the garage, then the only way out will be to isolate the entrance to the basement.
Popular waterproofing methods
Waterproofing the garage can be done in one of the following ways, depending on the characteristics of the structure, the level of groundwater and the material capabilities of the owner:
roll - with the use of floating or self-adhesive materials;
painting - using waterproof compounds;
penetrating - protecting the concrete base from the inside;
backfill - for rooms with intense mechanical impact on the floor.
Roll
Waterproofing a concrete floor in a garage using roll materials, for example, roofing material (the price for this type of waterproofing is the most attractive compared to other materials). Also, other products, floating or self-adhesive, can be used as waterproofing.
Before laying roll materials, the surface is cleaned, sagging is removed and the concrete base is primed. After the floor has completely dried, bituminous mastic is applied to it, after which, with gradual heating, roofing material or other material with similar properties is unwound.
Among the advantages of this type of waterproofing are low cost, the ability to work locally in case of repair, long-term protection from moisture and excellent adhesion to concrete.
The disadvantage of roll materials is the need to use a gas or gasoline burner for laying, as well as the release of toxic substances when heated.
Paint shop
In this case, the following are used as a waterproofing material:
bitumen-rubber mastics;
bitumen-polymer mixtures;
one-component polyurethane bases;
cement-polymer mastics.
Due to its liquid structure, the composition penetrates into all cracks, fills cavities and seals them from moisture. Among the advantages, it is also worth noting the presence of mold-fighting components in the mixtures, elasticity, excellent adhesive qualities.
Mastics are applied to the concrete surface only after thorough cleaning, removing all dirt and irregularities. Experts recommend first partially removing the layer of the old screed, treating the floor with mastic and then pouring the final screed. The cost of waterproofing the garage in this way will be justified by the long term protection from moisture.
Penetrating
Penetrating mixtures for waterproofing garage floors are made on the basis of cement, quartz sand and a number of synthetic components. They are divided into 3 groups:
concreting - increase the strength characteristics of the concrete floor, increasing its density;
polymer-cemented - environmentally friendly new generation compounds;
cement inorganic water repellents - used in the process of pouring a concrete floor.
The application of impregnations is carried out only when the base is completely cleaned from contamination; after the composition has dried, it is recommended to apply a topcoat.
Loose insulation
Backfill waterproofing, as a rule, is applicable in the case when a significant mechanical load is planned on the floor in the garage and there is a close location of groundwater.
In this case, ash, perlite, mineral wool, bentonite, placed in the formwork, are used as filling material. The advantage of this method of waterproofing is a long service life and reliable protection from moisture.

High humidity in the garage threatens the appearance of mold and mildew on its walls, rotting of wooden structural elements, corrosion and rusting of the car body and other metal parts, and it has a destructive effect on the foundation. Usually the cause of moisture is poor waterproofing of the garage floor, which should protect the room from moisture penetration and prevent cracks. Let's consider in this article how to correctly complete this stage of construction.
When starting the construction of a garage, it should be remembered that it is much cheaper to immediately correctly perform waterproofing in compliance with all the rules and recommendations than to deal with high humidity during the operation of the room and at the same time eliminate all the unpleasant consequences caused by it. Improper waterproofing of the floor can also lead to flooding of the garage with ground or flood waters, and if there is an inspection pit in the structure, moisture will constantly accumulate in it, the evaporation of which will damage the machine parts.
Speaking specifically about the floors, they are much less likely to undergo reconstruction than all other elements, since this procedure is considered quite costly both in terms of finance and labor costs, therefore it is not worth saving at the construction stage, it is better to immediately purchase high-quality materials that can serve for a long time.
The "right" building materials
To prevent the appearance of water in the garage, you need to be very responsible in the choice of materials. In no case should you choose expanded clay, foam and gas blocks, as well as silicate bricks for construction. In principle, it is not advisable to purchase any brick, since it does not belong to waterproof materials. If the brick layer can still contain a little moisture, then with a constant backwater of groundwater, it is quickly saturated with moisture and collapses. That is why concrete is most often used in the construction of a garage.
On the modern market, there is a huge range of insulation materials that differ in installation technology, price, and duration of use. Bituminous materials, usual in our region, with proper operation, serve up to 10-15 years, and new polymer waterproofing practically does not wear out, which allows them to be laid for the entire service life of the structure. A large number of different membranes are also offered, but when buying them, despite all the assurances of the sellers about the reliability and efficiency, it must be borne in mind that the thickness of such a material cannot be less than 1.5-2 mm. All super thin membranes are not suitable for waterproofing garage floors. In addition, such insulation requires a lot of experience of the performer and specialized equipment, so you should not even try to install it yourself.
Garage floor waterproofing membranes should not be thinner than 1.5 or 2 mm
The main types of waterproofing
Consider the main types of waterproofing:
- Plastering, or as it is also called coating, is a thin layer of special solutions that prevent moisture penetration.
- Oleechnaya - roll or sheet materials glued to hot mastics, such as bitumen.
- Penetrating, the youngest type of waterproofing. In this case, the surface to be treated is impregnated with liquid water-repellent solutions.
- Powder waterproofing is a cross between the first and third types.
General floor waterproofing technology
After the place for the construction of the garage is marked out, all the soil in this area is carefully compacted. This helps to prevent its settling during operation. Now a layer of coarse sand about a meter thick is applied to this site, which also needs to be tamped. Next, a "layered" structure is laid on the sand, consisting of three layers of geotextile, while a waterproofing material must be laid between the lower and middle, and a layer of thermal insulation between the middle and upper. Now you can start laying the floors.
It is best to make a concrete floor in garages. To increase resistance to damage, it can be reinforced, while the iron frame must be welded so that its structure is unbreakable. The thickness of the concrete layer should not be less than 15 cm.
It is advisable to carry out waterproofing of the foundation and floor in garages during the construction period, since these elements are least often reconstructed.
Additional waterproofing in garages
Consider a garage without a basement first. In this case, it is sufficient to prevent moisture penetration into the lower part of the walls along the entire perimeter of the structure. For this, horizontal waterproofing is performed from two layers of roofing material glued to the wall and to each other with hot bitumen mastic. This layer must be laid above ground level at the junction of the walls and foundation.
Before waterproofing a garage with a basement, it is imperative to take measures to prevent the ingress of groundwater and capillary moisture into it. To do this, add vertical waterproofing to the above method, extending under the outer walls. As a rule, it is located at the level of the lower part of the foundation and captures the outer edges of the outer basement walls. One of the most effective methods is the application of a layer of cement to the outer side of the foundation and processing it with hot mastic in two layers.
Applying bitumen mastic to the outer part of the basement part of the garage to exclude the penetration of atmospheric moisture and capillary suction
When the basement floor is placed below the groundwater level, there is a risk of flooding. In this case, the process of waterproofing the basement and garage floor is somewhat complicated. After all the above measures for waterproofing the lower part of the foundation have been taken, the basement floor must be concreted and its surface must be leveled using a screed. Now you need to stick two layers of roll or sheet waterproofing on the bitumen, while it is imperative to connect the places of their contact with the layers of insulating material previously laid under the garage foundation with hot mastic. Similarly, we connect the vertical waterproofing applied to the outer surface of the outer walls with the one located under the foundation. After that, you can proceed to waterproofing the garage floor.
Video: the use of liquid rubber
Waterproofing the floor in the garage should be taken seriously and it is better if it is carried out by real professionals, since only they are able to take into account all the features of the area, reliably prevent flooding of the structure and eliminate the high humidity in it.
Waterproofing they call the protection of a room from the ingress of groundwater, precipitation and chemical liquids inside. She may be external and internal... Floors, vertical surfaces and roofs are covered with waterproofing materials.
How to waterproof a garage?
Waterproofing works must be carried out from the beginning of the construction of the garage. Errors made when waterproofing the foundation, then very difficult to fix... Most people choose roofing material and bitumen alloys as materials. Of course, their service life does not exceed 10 years, but on the other hand, it does not require large cash costs. You can purchase formulations with polymers that will last 2 or even 3 times longer.
For a start it is worth taking care of protection of the foundation... On a sand and gravel bed around the perimeter of the room, where the foundation blocks will stand, roll materials are rolled out. After the foundation is poured or installed, the surfaces are treated with polymer-bitumen mastics both from the outside and from the outside.
The same compositions are suitable and to protect the floor... For additional external protection can be used clay castle... Therefore, the foundation pit exceeds in terms of area, the size of the garage.
If the basement in the garage was not provided, then you can horizontal waterproofing of the garage do it yourself. The concrete floor is covered with roofing material or a layer of bitumen-polymer mastic, then reinforcement is mounted on the weight (supports are used), the metal structure is again poured with liquid concrete.

How to check the water table?
When there is no idea at what level the groundwater is at the construction site, then it makes no sense to start it, as it will be akin to building a "castle on the sand". First you need to look around the area, if there are any wells nearby. The water level in them will indicate at what depth the underground waters are. But the lack of wells is not a cause for panic.
Next step: study of vegetation on the surface of the earth. Moss, reeds, pussy willow, and other plants growing predominantly in marshy lowlands report that groundwater is located close to the earth's surface. To make sure that your guesses are reliable, there is one more and, perhaps, the surest way to check: well drilling.
If everything is confirmed, then you need to think carefully before building a garage with close water. After all, it will take a lot of effort to build high-quality waterproofing.
Clay castle
Clay castle- this is a layer of clay, which covers the bottom and walls of the pit so that moisture does not violate the integrity of the walls, floor and water does not get into the garage from the outside. This is a necessary measure if a viewing hole and a basement are provided in the drawing. The pit, in which the foundation blocks will be installed, must provide for free space between the foundation and the ground, in which the clay will be laid in layers.
The clay is spread over the floor, forming a layer of approximately in 100 mm., gravel is laid on it, then a sand cushion. It will be installed foundation.
But before that, it is necessary to make the walls of the pit waterproof.
For this, balls - "apples" are made from wet clay, which are flattened from 2 sides and leveled along the walls of the pit. Clay layer thickness - from 5 to 10 cm.
What is the best clay to use for a clay castle? It should have a fairly high percentage of fat - not less than 15%.
It is very simple to check whether the natural material is suitable for the castle or not: you need to add a little water to the clay and knead it, turning it into a pliable lump.
If cracks form, then the clay is too dry... A smooth surface indicates that the clay can be used for water resistance. To increase the plasticity of the material, builders add to it 20% lime.
It's even better when the clay is harvested from autumn and will lie under the snow during the winter months. During this time, water particles will be able to penetrate the clay at the molecular level, turning it into a plastic, pliable mass.
But there is one caveat: in severe frosts, the walls of the pit can freeze through, and in this state the clay "swells", increasing in volume and can deform the walls of the room itself.
Waterproofing of foundation blocks and inspection pit
As options, compositions are considered that, in a molten state, can be applied to the surface of the foundation or roll materials. They can also be used for waterproofing garage ceiling and floor.
Bitumen in a heated state, they are applied to the walls with a roller, paying special attention to the joints. The cracks can be covered with bitumen mastic, to which you need to add a little gasoline. The problem is that when applied to walls, the bituminous material does not adhere well to the working surface. Therefore, for a start, the foundation blocks are treated with a composition that plays the role primers.
It is called - primer and consists of gasoline and bitumen. On such a solution, a layer of pure bitumen will settle firmly.
Another option, in which rolls of roofing material are used, is no less effective. Vertical surfaces must first be cleaned of dirt and dust, apply primer, lubricate with molten bitumen, and then apply roofing material to the hot mass - bitumen acts as glue.
It should be borne in mind that when laying such materials, joints are formed, therefore, pieces of roofing material are stacked overlapping each other. Overlap width - not less than 10 cm.
When waterproof protection is installed on the foundation blocks, you can proceed to the brickwork of the walls.
It is unpleasant when, in the event of a violation of technology or errors during construction, some points were not taken into account, and in the inspection hole appears moisture.
What materials can be used to protect walls and floors in this case?
- polymer membranes;
- penetrating compounds;
- roll materials;
- liquid rubber.
The life of polymer membranes is not limited, but they are expensive in terms of cost. The joints between them have to be fastened hot air... Penetrating formulations are available in the form of powders. They are diluted with a little water. When the composition becomes homogeneous, it is applied to the work surface.
Roll materials are stacked in several layers overlapping each other. The joints are glued molten bitumen... When laying, liquid rubber creates a layer equivalent to 4 layers of roofing material. This is a very effective way to protect yourself.
Protection of walls and floors in the basement from the inside
When waterproofing a garage from the inside from groundwater, two types of protection are used:
- injection (penetrating);
- coating.
For waterproofing the floor, hydrophobic materials are used (roofing material, mastic, etc.), on which it is then poured concrete screed... If cracks in the floor were noticed before work, then the screed is performed after the reinforcement has been installed. It will not allow materials to deform. In the place of joints and the floor, you can install bentonite cord- it will swell and prevent moisture from entering the room.
The wall in the garage is leaking, what should I do?
If you are interested in how to waterproof a wall in a garage, then things are a little more complicated here.
The most effective waterproofing method is use of penetrating materials.
But this will require special equipment for pumping the composition into the previously made holes in the wall. The method is quite expensive and time-consuming, therefore, to protect the walls of the basement in the garage, they are often used coating materials.
Such compositions contain polymers, which, when cured, form a durable moisture-proof layer. But before that:
- walls must be thoroughly cleaned of dust, dirt;
- dry the work surfaces;
- if the walls are made of blocks, expand the walls by 5-10 mm. and fill the resulting gaps with a coating material;
- apply the composition in a continuous layer on the walls.
Compositions are in demand "Penetron", "Hydrohit", "Maxil" and etc.
What to do if water gets into the garage?
Garage rainwater or ground water- not yet a reason to panic. A properly installed drainage system will allow water to drain away without getting into the room. There are 2 drainage systems:
- external;
- internal.
The essence of the first is that you need to dig deep trench 40 cm wide. around the outer perimeter of the garage. The bottom of the trench should be approximately 40 cm below the floor level. Wells are drilled every 2 meters to the depth of the parent sand. They are equipped with polymer pipes, previously wrapped in geotextiles.
Pipe outlets should be protected with a fine welded grating to prevent solids from entering. At the bottom of the trench is laid geotextile, then crushed stone is poured and its layer must be wrapped with the edges of geotextile. The trench is covered with gravel.
The internal drainage system differs in that the work takes place indoors... To dig a trench, you need open the floor... The trench is obtained with a shallow depth - 40-50 cm. Pipes with a diameter of 20-110 mm. stacked horizontally. Each of them should have holes of 4-5 mm. throughout the pipe.
For each meter, 3 mm is observed. slope. The pipes are laid on a layer of crushed stone. They should be directed towards drain well, which you can buy ready-made or make yourself.
