Waterproofing of building structures.

Waterproofing building structures - a guarantee of their reliable operation throughout the entire life of a building or structure. Protection is arranged on all elements exposed to moisture.

Types of impacts

The effect of water can be different, therefore, insulation must fulfill certain functions to prevent specific undesirable consequences:

1) Anti-filtration waterproofing is to protect structures directly exposed to water: underground and hydraulic structures, underwater elements, tunnels, wells, etc.

2) Anti-corrosion waterproofing is designed to prevent the harmful effects of an aggressive humid environment, chemicals that can disrupt the structure of materials and structures made of them.

Most of the construction projects are made of reinforced concrete. Concrete itself is not afraid of water - its strength only grows from its impact. However, the chemical impurities included in the liquid are able to wash out calcium and other substances from the stone that affect its technical characteristics. In addition, with prolonged exposure to water on concrete, it is able to penetrate deep into the body of the structure and damage the reinforcement cage - this is a real threat to the entire element, since the metal oxidizes and rusts, losing its bearing capacity... That is why waterproofing of building structures is necessary for all structural elements without exception.

What is protection

Depending on the method of installation, waterproofing, materials for it lend themselves to the following classification:

The most common are coating and roll waterproofing. They are easy to use, affordable and versatile.

Protecting the house

During the construction of residential and public buildings use almost all types of moisture-proof materials. The feasibility of their application is calculated at the design stage, when all possible negative impacts are taken into account. Waterproofing a house from foundation to roof is mandatory to ensure the normal functioning of all elements and safety, respectively. In addition, it is necessary when laying insulation: it can only perform its functions in a dry state.

For each individual structure, special waterproofing, materials for its implementation and the method of their application are used.

Foundation

The base is the most important construction of the house. In most cases, in private construction, the foundation combines the function of a common support and basement. Not only the quality of work of all structures depends on its condition, but also the health of the person living in the house, the sanitary situation in the premises.

Reinforced concrete is most often used as the material for the foundation. It is important to protect it from the following destructive effects:

• Waterproofing from groundwater outside. This is especially important if their level is above the level of the basement, then the protection must be anti-pressure. For this, roll materials are used in conjunction with a triple drainage system.
• Waterproofing the basement and foundation walls from the inside to prevent the formation of condensation, the penetration of groundwater during their capillary rise.

How to protect the strip foundation

Internal and external walls of the base perceive different water influences, therefore, different types of insulation are used for them.

The outer surface of the base in contact with soil and water must be as reliable as possible. For a waterproofing device use:

• Roll materials. Roofing material is used more often, but it can be replaced with other, more complex insulators made of polymers. They are similar in properties, but the latter are more durable, this is important with a high level of groundwater and soil mobility. Rolled waterproofing is applied to a flat, pre-cleaned from dust wall by gluing it to bitumen mastic in several layers.
• Polymer lubricants are suitable for protecting the foundation from slight capillary rise of the groundwater level. For significant impacts, the coating is not suitable - it is easily deformed even at the stage of backfilling of the earth during construction and requires repairs, which are difficult to carry out in this area. More often it is used to protect shallow foundations with a minimum level of groundwater.
• Sprayed waterproofing requires special surface preparation and complex application, therefore it is often used at the joints of the foundations of several buildings, where traditional materials are difficult to attach. Also in hard-to-reach areas, its device is irreplaceable.

Columnar, pile foundations

Waterproofing of such types of bases is carried out through the appropriate processing of working structures. For piles and pillars, concrete with a high class of water resistance is used, wooden elements need to be impregnated with special compounds, strip foundation protect the grillage with roll or coating materials and with the help of a blind area that minimizes the ingress of water from the environment.

Perimeter barrier

The foundation is affected not only by groundwater, but also by precipitation in the form of rain, melting snow. To prevent their negative influence, a blind area is needed. It is installed around the entire perimeter of the house after installing the foundation, of which it is a part.

The width of the blind area should exceed the overhang of the eaves by at least 20 cm and have a slope of less than 20 for water flow.

The perimeter device is produced according to the following algorithm:

1) Remove about 250 mm of soil and compact the surface.

2) Lay a cushion of gravel-sand mixture ≥150 mm thick.

3) Installation of formwork along the outer perimeter.

4) Installation of a frame mesh made of 6-12 mm reinforcement in 100 mm increments. Of course, it may not exist, but with it, the future structure will be able to withstand heavy loads, which will reduce the risk of its breakdown.

5) Concrete pouring and leveling.

It is important to create compensation gaps that protect monolithic structure from deformations that may occur during house subsidence and ground movements. For this, boards perpendicular to the house are laid in the formwork at the height of the blind area at a distance of 1.5-2.0 meters, and a layer of roofing material with a thickness of ≥ 10 mm is arranged along the perimeter of the wall itself.

Basement

Waterproofing of building structures must be carried out in a comprehensive manner to be effective.

The room located at the foundation level must be dry and sealed. Basement waterproofing includes the treatment of both walls and floors with waterproof compounds and materials.

Floors sealed by concrete base... It is well cleaned of dirt and dust, rolled materials are rolled out from above. The number of coating layers depends on the level of groundwater: if it is below the floor level, it is enough to lay roofing material or another polymer 2-3 times on top of each other, smearing each level with liquid mastic. With an increased GWL, there should be more layers.

Walls the basement is being built using special technologies using clay locks built into the masonry. The room itself should be treated with anti-capillary compounds. For these purposes, it is perfect coating waterproofing: It follows the contours and unevenness of surfaces. With an increased GWL, roll insulators can be used. Also, the walls are treated with plaster compounds made of concrete and cement with a high level of water resistance. In this case, in addition to waterproofing, insulation and decoration of the room are simultaneously performed.

Walls

Complex waterproofing of building structures is the key to the durability of the building. It is especially important to protect critical and large elements: the integrity of the whole house depends on the reliability of their work. The larger volume of any structure is made up of walls. That is why special attention is paid to their device.

The outer surface is actively in contact with water: rain, melting snow can penetrate into the wall materials, with prolonged exposure to them, humidity increases in the room, fungi and mold develop. Waterproofing walls from the inside can be done in the following ways:

1. Treatment with penetrating primers and compounds.
2. Pasting the surface with membranes.
3. Plastering with solutions containing moisture resistant additives.

Waterproofing interior walls in one way or another depends on their design and the type of further finishing. All options are effective and able to withstand high humidity from outside.

All joints of walls and ceilings, conjugation of dissimilar materials, expansion joints of structures require careful study.

Wall waterproofing is necessary in rooms with high humidity: bathrooms, toilets, saunas, production workshops. To ensure it, finishing components are used that are resistant to moisture: primers, plasters, tiles.

For external walls made of materials unstable to moisture, plaster, tiling, stone are used. It will not be superfluous to pre-treat the surface with a waterproof primer or coating insulation.

Roof

Roof waterproofing is designed to protect indoor spaces and structures from moisture seepage from external precipitation.

Roof structures have a complex multi-layer structure, in which significant temperature differences are formed, from which condensation occurs on the inner surface of the coating. To prevent this from happening, it is important to correctly design the "layering" of the roof. Provision should be made for ventilation and moisture removal. The waterproofing material contributes to the formation of breathable contours when combined with a coating and insulation in a special order determined by the design of a particular solution.

Roof waterproofing can be made of the following materials:

• Plain plastic wrap.
• Polypropylene film.
• Non-woven membrane.

The choice of this or that material depends on its properties and their relevance in a given design. For example, some insulators allow vapors to pass through but retain water. Others work differently on both sides (one is moisture / water permeable, the other is not). Some specimens require an air gap in the bedding.

Rest zone

Pool waterproofing always means protection from both sides - inside and outside. Its device is similar to the protection of a foundation: the outer part is subject to aggressive groundwater and soil movement, therefore, for protection, they are glued with roll materials, for example, several layers of roofing material. To create a bowl, it is advisable to use concrete with special additives that make the stone resistant to water.

Internal waterproofing of the pool is done before finishing... What is it made of:

• Membrane materials. They do an excellent job with their work, but installation requires the participation of specialists.
• Liquid rubber.
• Lubricants in the form of a paste, after hardening, turning into a waterproof material.
• Liquid glass.

These types of treatments are ideal for the pool: they withstand high water pressure, do not deform and do not change their properties with prolonged exposure to moisture.

Why waterproof a pool if it is surrounded by water on all sides?

The bowl is made of reinforced concrete, which is able to actively absorb moisture. If the stone only gains strength from this, then the reinforcement in its body begins to rust, losing its bearing capacity. Thus, pool walls can weaken and collapse over time.

Waterproofing protects against the damaging effects of water. It is mainly used for foundations, basements and floors, as well as various surfaces that are in direct contact with moisture.

Types of materials

Construction waterproofing is of the following types:

• conventional and welded roll coatings are short-lived, require replacement after 5 years, the longest service life is 10 years;
• mastic - mainly needed for sealing cracks and as an insulating material;
• dry mixes and hydrophobizing liquids are modern building materials that are in great demand, convenient to use and do not require replacement for a long time.

Range offered

In the online store site you can purchase inexpensive waterproofing of the firm "Indastro" in three varieties:

• tough - is needed to isolate from moisture. It is a dry mixture of cement and modifiers, environmentally friendly. If the foundation, basement, basements, pools, water tanks and other structures in contact with moisture have a mineral base that is not subject to deformation, then it is better to use it;
• hard penetrating - used to compact the structure of concrete, is a mixture of cement and fractional additives, applied to ready-made concrete. It is suitable for the treatment of structures both inside and outside, it is especially worth covering pipes, tanks, pools, water towers with it;
• elastic - serves to protect surfaces subject to deformation from moisture. It always uses several means: a dry mixture of cement with modifiers and an aqueous solution of polymers. It is needed for unstable mineral foundations of structures.

What are the pros of using

The elastic mixture is resistant to salt and air, it prevents cracking and is safe for drinking water. The hard type is also resistant to salts and weathering, can come into contact with drinking water, and it also has a high resistance to mechanical loads. The penetrating hard mixture is easy to use, is able to form a barrier due to the pressure difference, and is a protection against aggressive substances.

The company "RosMasterStroy" offers you a wide range of waterproofing materials for all types of construction work.

Hydroizol- waterproofing non-covering bio-resistant material, produced in the form of rolls 0.95 m wide and 20 m long. It is used for waterproofing the underground part of buildings from the effects of groundwater (pool bowls, basements, garages), and as anti-corrosion coatings for underground structures (pipelines, tunnels, mines, pumping stations, collectors), GI-K - to protect flat roofs.

Steam waterproofing films - represent a modern roll material for the protection of thermal insulation, roof and roof components as well as load-bearing structures from steam and moisture. The film consists of several layers of polyethylene. A vapor barrier film is selected taking into account the scope of its application and the degree of humidity in the room. technical characteristics, which include the degree of vapor permeability, mechanical strength, the ability to remove vapor and condensation from the room.

Penetrating waterproofing - is a unique system for protecting concrete from water and aggressive environments. Waterproofing is actively used in residential, industrial and business construction. The use of penetrating waterproofing does not require draining the structure. The penetrating waterproofing is certified for use in contact with drinking water. In addition to increasing the water resistance of concrete, penetrating waterproofing also improves the strength characteristics of concrete structures.

Building bitumen - used for roof repair, waterproofing of foundations, basements, bathrooms, etc. Building bitumen is used for waterproofing concrete products, waterproofing foundations, for filling cracks, preliminary priming of the base, under soft roof... Bitumen is either a solid or a viscoplastic material (thermoplastic material), a resinous product.

Waterproofing mastic - it is used to protect against moisture located in the ground building structures made of concrete, reinforced concrete, wood.
With the help of polymer waterproofing mastic, high-quality insulation is achieved. Another popular area of \u200b\u200bapplication is the installation of seamless waterproofing coatings in basements, swimming pools, helping to protect the foundation and other structures from corrosion.

Bitumen primer -The bituminous primer is used for the preparation (priming) of insulated surfaces (concrete slab, cement-sand screed etc.) before laying welded and self-adhesive roofing and waterproofing materials. Bitumen primer is produced in two types: concentrate and ready-to-use. The primer is applied to a dry and cleaned surface with brushes or in bulk with leveling with special strokes, a roller, a spatula or a brush.

Glassine - roofing felts substitute, roll roofing materialmade of roofing board impregnated with petroleum bitumen. Glassine is used as a lining material for the lower layers when installing a roof. To protect the insulation from moisture, they are lined with glassine on one or both sides. Glassine is used with an overlap of 100 mm, or glued with adhesive tape, mastic, adhesive tape. For insulating against fumes and condensation between wood-based materials and reinforced concrete substrates (floor, walls).

Roofing materialis a roll roofing waterproofing material, The scope of application of roofing material is very wide: from waterproofing to roofing.
Roofing material has the following designation:
"P" - stands for roofing material.
"K", "P" - roofing or lining.
"K", "M", "P", "CH" - type of dressing (coarse-grained, fine-grained, dusty, scaly).
300, 330, 350, 400 - density of the cardboard base (g / m 2).

Fundalin-Made of a two-layer composite 0.6 mm high-density polyethylene membrane. Profiled membranes Fundalin (or Fundalin drainage sheets) are used as a protective layer for insulation, for sanitation of damp walls from the inside and outside, for the organization of inversion and "green" roofs , for the organization of drainage of support walls, drainage of tunnels and highways.

Hydrostop-applied for protective treatment of porous building materials - bricks, concrete, plaster, natural stone, slate, tiles, paving slabs etc. Gives water-repellent properties to the treated surface. In addition, "Gidrostop" is fireproof and explosion-proof, increases the frost resistance of the surface and prevents the appearance of so-called "efflorescence" on it. And also has antifungal (fungicidal) properties, which increases the service life of the structure as a whole.

GLIMS Waterstop-sealing cement mix It is used for quick and economical sealing of swimming pools, reservoirs (including drinking water), foundations, basements, bathrooms and toilets, etc., used for external and internal work on concrete, stone, brick, plastered surfaces. The sealant cement mixture can be applied to wet (not wet) bases; resistant to salt solutions, diluted acids, alkalis and petroleum-based mixtures; high adhesion; morozo- and atmosferostoykost; high safety; low modulus of elasticity; operating temperature range from -50 ° to +70; Eco-friendly and safe.

Polyethylene film -used in roofing, facade and foundation works. Polyethylene film does not allow moisture and vapors to pass through and therefore is a good hydro- and vapor barrier material. Covering freshly laid concrete with construction polyethylene film improves the conditions for its hardening - reducing moisture evaporation, it provides a sharp increase in the strength of products and eliminates the need for additional moistening of concrete products. A film placed under the concrete and on top of it provides more complete hydration of the cement.

When building any structure, you should always take into account environmental factors. Rain, snow, underground currents, etc. destroy an unprotected object, as a result of which it loses its strength and falls into the category of "demolition". Compliance with all the rules and recommendations will allow your building to stand for many years and even centuries.

Waterproofing is effective method protection of any structures, buildings, premises and any other objects from water penetration. In this case, special water repellent materials, capable of preventing the processes of decay and destruction of the building. Thus, waterproofing protects the building material from the harmful effects of washing or filtering water and increases its reliability and durability. Waterproofing of construction sites is a prerequisite for high-quality construction.

We offer you only high-quality modern roll welded waterproofing materials. At the same time, traditional waterproofing is widely represented: roofs - euroruberoid, roofing material, glassine, bitumen, bituminous mastic, insulating mastic.

HOW WE ARE WORKING

Waterproofing is one of the most important stages of construction and renovation works... It includes actions to protect building structures from unwanted moisture. High-quality waterproofing will ensure successful and reliable operation of the building in the future.

For the implementation of waterproofing are used waterproofing mixtures, which are necessary for sealing internal and external works, foundations, pools, basements, as well as for work with surfaces different types... Such mixtures are most resistant to acids, alkalis, salts, low and high temperatures and are environmentally friendly building materials.

Waterproofing, depending on the goals, is usually divided into two types: anti-filtration and anti-corrosion. According to the method of the device, plastering, painting, pasting, cast, impregnating, injection, filling, mounted insulation are distinguished. By the type of the main material, waterproofing is mineral, asphalt, metal and plastic.

Anti-filtration waterproofing used to protect against water ingress into underwater and underground structures, through retaining hydraulic structures, as well as to prevent the leakage of operational and technical or waste water.
Anti-corrosive waterproofing is used to protect structures from water, chemically aggressive liquids, harmful effects of the atmosphere, as well as from electrocorrosion, which can be caused by stray currents.
Plaster waterproofing is most often used for reinforced concrete structures and is a multi-layer coating.

Paint waterproofing executed in the form of a thin coating, which consists of polymer and bituminous varnishes and paints. Such insulation is used for anti-capillary, anti-corrosion protection of metal and reinforced concrete structures.
The glued waterproofing is a waterproof coating consisting of several layers of rolled materials such as roofing material, glass roofing material, hydroglass insulation, glass felt, brizol, waterproofing and others. Waterproofing is characterized by increased crack resistance, and is carried out on vertical and horizontal surfaces. The glued waterproofing of structures is considered popular due to its durability and reliability.
Impregnating waterproofing is most often used for prefabricated elements, which are most susceptible to intense mechanical stress, and is also used for internal waterproofing of foundations and basements from, during the repair of concrete structures. This type of waterproofing is highly resistant to chemicals and provides protection against corrosion.

Cast waterproofing is the most reliable type of waterproofing, however, due to the complexity of its application, it is performed in the most critical cases.
Injection waterproofing is used with the use of new polymers of a wide spectrum of action and is carried out by injecting a binder into the seams and cracks of building structures.
Mounted waterproofing is used in difficult cases and consists of specially made elements that are attached with erection ties to the main structure.
Backfill waterproofing is similar to the construction of cast waterproofing, however, it has a large thickness and complex thermal and waterproofing purpose with low water resistance.
Company " Construction material»Provides a wide selection of waterproofing materials to help protect structures from moisture and ensure their durability.
