Types of waterproofing. Waterproofing of structures. Liquid glass for waterproofing

In the protection from water, all surfaces and structures that in use can come into contact with moisture are needed. If we are talking about a country house, then here it is necessary to include roofs, cellars, and also foundations. Inside the apartment or home are bathrooms and bathrooms, where flooding and leaks are possible.

Inside the structures, waterproofing is required for insulation materials that need to be protected from rain and condensation. Protecting materials from water is not only necessary where there is a possibility of penetration, but also where condensate and washings can adversely affect the design. For this, different types of waterproofing are used today, which can be classified according to the place of application and purpose.

Varieties of waterproofing at the place of application and time of use

Considering the types of waterproofing, you should become more familiar with materials that are classified at the place of use. Materials for such work may be designed for external or internal application. Internal waterproofing is a whole complex of measures that allows to protect materials from water inside the premises. This includes the work on the waterproofing of the floor and walls in the bathroom.

Outside the structure is used external waterproofing. For example, the foundation needs protection from groundwater. Considering the types of waterproofing, you should especially highlight the materials that are classified by the time of use. Thus, waterproofing can be primary and secondary. Primary is used during the construction phase of the facility, while the secondary is used for repair.

For example, if for some reason the primary waterproofing has been damaged or does not cope with the tasks assigned, then measures for secondary waterproofing are being carried out. The old coating must be removed, the surface cleaned, and then a new layer of waterproofing applied. Sometimes technology is used when a new layer is applied over the old one.

Varieties of waterproofing according to purpose and features

Different types of waterproofing are on the market today. They can be subdivided by features and purpose, among them it should be noted:

• Anti-pressure;
• Non-pressure;
• Anti-capillary;
• Superficial;
• Sealing.

Anti-pressure is used to protect against positive water pressure. If the groundwater level is high enough, the external walls of the basement should be protected by anti-waterproofing. In this case, materials are used that will be able to undergo a positive water pressure.

Non-pressure waterproofing is used when it is necessary to protect the structure from negative water pressure. Such work may be required in case of heavy precipitation or spring floods that accumulate around the basement. Protivokapillyarnaya waterproofing allows you to protect materials from raising moisture through the capillaries. Such work is required due to the fact that many building materials have the ability to suck in water, which then rises upward. Among others, one should distinguish bricks and concrete.

Varieties of waterproofing by the method of arrangement

Considering the types of waterproofing, you will also learn about the materials, which are subdivided according to the method of arrangement, they can be:

• Painting;
• Plastering;
• Cast;
• Injecting;
• Mounted;
• Film;
• Lubricating;
• Okleychnymi;
• Impregnating;
• In bulk;
• Structural.

Use of coating waterproofing

Waterproofing of structures is often carried out with lubricating materials, which are represented by mastics, two-component and one-component elastic compounds. Their application is carried out by a layer with a thickness ranging from 2 mm to 6 cm. Such waterproofing of structures is used for external protection of building elements.

Quite often, waterproofing is used for foundations to protect them from groundwater. Mastic can also be used for interior work. In this case, it covers the walls of the basement or bathroom. With the help of a waterproofing coating, cracks can be eliminated.

The coating materials are represented by bitumen-containing compositions. Among the advantages of such a solution is cheap. However, there are also disadvantages, which are expressed in fragility at low temperatures. Bitumen begins to lose elasticity when the thermometer's column drops below zero. If deformations occur during this period, it will cause the formation of ruptures and cracks. Over time, the material can also completely exfoliate from the surface.

Bitumen mastic for waterproofing is ready to serve about 6 years. The material breaks down sometimes after four winter cycles. The disadvantage of using such waterproofing is also the danger of working with hot bitumen. In addition, the surface requires careful preparation. It should be cleaned of deposits, debris, dust and mortar.

Work on the application of lubricating waterproofing can be carried out only in dry weather. Having considered all the features of this approach, it can be concluded that bitumen mastic for waterproofing can be used only in those cases when the probability of leaks is sufficiently small. This should include an example in which the level of groundwater is low. This technology on the roof is already irrelevant, because in the frosts concrete cracks, and the ice becomes the cause of material ruptures. As a result, by the spring the surface loses its tightness.

Features of waterproofing

Oakleychnaya waterproofing involves the use of roll materials, which are stacked in several layers. This approach is used only for external anti-waterproofing. The most popular solutions for conducting such work are:

• Ruberoid;
• Only;
• Bituminous materials based on fiberglass;
• Parchment;
• Polymerized bituminous materials;
• Rubber bitumens.

If the external waterproofing is carried out with the help of modern rolls with polymer additives, then it will be possible to achieve a positive result. The layer of waterproofing will be durable, its surface does not form mold, it will not be rotted. Advantages of pasting materials can be considered the possibility of their laying on different surfaces of the type:

• Wood;
• Metal;
• Concrete;
• Flat slate;
• Old roll cover;
• Asphalt concrete.

Such waterproofing is waterproof, resistant to aggressive environments and economical. However, the surface must first be carefully prepared. It is important to eliminate irregularities that exceed 2 mm. Fusing or gluing should be carried out with special care.

Work can begin when the thermometer has risen above + 10 ° C. Under the influence of mechanical loads, the material can tear, so it is desirable to protect it. Quite often, according to this technology, waterproofing of the foundation is carried out today. Types of waterproofing, having considered, you may decide that these options do not suit you. This may be due to the need to additionally perform a pressure wall. In addition, it is important to ensure a low level of surface moisture before gluing the material. If the concrete is wet, adhesion will be absent.

Paint waterproofing

The paint coat is applied in thicknesses ranging from 3 to 6 mm. The film is quite elastic and has no seams. You can be carried out a waterproofing bath for the tile. However, paint mastics are also used for external works. With the help of these formulations, it is possible to deal with crumbling, cracks and erosion. As materials, bitumen mastics with asbestos and talc additives are used, as well as compositions based on synthetic resins. Such technologies are cheap. It is worth highlighting the advantages of vapor permeability and abrasion resistance. However, there are shortcomings, one of them is expressed in fragility. This coating is ready to serve for about 6 years.

Sprayable liquid waterproofing

Quite often waterproofing is carried out by spraying liquid materials. They are represented by polymer-bitumen emulsions, which are created on a water basis. Such mixtures are also called liquid rubber. They can be one- or two-component, and the application is carried out with the help of special equipment. This approach is relevant not only for cellars, but also for roofs. Advantages can be called the ability of liquid rubber to fill even small pores.

Waterproofing the pool with liquid rubber makes it possible to form a sealed coating. Before you start, you must take into account some of the shortcomings of this method, they are expressed in a temperature regime, which must be kept within certain limits. Liquid rubber can be used only at +5 ° C and above.

In the process of operation, such waterproofing should not be damaged. She's afraid of puncturing. Before coating, dry the surface and make sure that it is not frozen. A complex relief will require a more impressive consumption of material, which causes a rise in the cost of work. Spraying is hampered by a strong wind, so you need to wait for suitable conditions to work.

Penetrating waterproofing

Waterproofing of the basement can be carried out with the help of penetrating materials, which are able to prevent capillary rise of water. A composition of this type is a mixture of:

• Active chemical additives;
• Fine-grained quartz sand;
• Portland cement.

The application is carried out on a wet surface, after which the composition begins to come into contact with water, forming crystals filling the capillaries, cracks and pores. The depth of penetration can reach 25 cm. Some manufacturers claim that the composition penetrates 90 cm deep into the concrete.

The waterproofing of the cellar using this technology is quite effective. If the foundation was not unearthed, then the processing can be carried out from the inside. Penetrating materials can be waterproofed with different capacities as silage pits. Among the advantages it is necessary to allocate the possibility of carrying out works inside the basement. At the same time, there is no need to dig a foundation. Do not dry the surface. The material after the waterproofing is protected not only from the outside, but also inside. He is ready to serve a rather long period. Concrete at the same time retains its ability to vapor permeability.

Waterproofing works in a wooden house

Waterproofing in a wooden house is necessary. To ensure that the floor boards do not become unusable before the time, a horizontal waterproofing must be laid between the foundation and the lower rim. Usually it is made of bitumen mastic and roll materials. In those places where the lag supports are located, it is also necessary to arrange waterproofing. To prevent the formation of condensation in an underground room, it is necessary to provide ventilation openings in the opposite walls.

The foundation must be covered from the outside with liquid or film waterproofing materials. Inside, too, must be waterproofing. The basement in this case will remain dry even during spring floods. As for the wooden floor in a wooden house, it can be protected with the following types of waterproofing:

• Painting;
• Cast;
• Okleechnaya;
• Impregnating.

Oakleychnaya waterproofing requires the formation of a continuous carpet of bitumen-polymer, bitumen or polymeric materials. Before you start laying the first layer, the rough plank floor or concrete slab is cleaned of debris and dust, leveled and treated with a primer. If the overlap is log or plank, then it must be treated with antiseptic compounds and fire retardants.

Then you should start laying the waterproofing material. Joints in their presence are glued, and the next layer is laid on top of the mastic, which is processed laid in the previous stage of the material. After this preparation, you can lay a clean wooden floor.

Insulation with ruberoid

Waterproofing ruberoid provides for the use of roll material, which is stacked by gluing. On the surface of the roofing material is strengthened with bituminous mastics. Viscosity of materials allows to achieve excellent results and provides protection of the socle, foundation or basement from the penetration of water. If the pasting of the roofing paper with the plaster insulation of the foundation of the brick, then it will significantly extend the life of the layer.

Use of liquid glass

Liquid glass for waterproofing is used today quite often. As the basis of the material is sodium silicate or potassium silicate, the latter option is more expensive. Application of liquid glass is carried out with the help of an atomizer or brush. In the first case, the mixture dissolves in water in a proportion of 1 to 5. This reduces the consumption. Liquid glass allows you to protect wood from fungus and mold, increasing its fire resistance. Liquid glass for waterproofing is also used as an intermediate layer before laying tiles or applying plaster. The outer layer is able to protect the surface from mechanical damage, mold formation and exposure to acids.

Waterproofing of the brand "Ceresite"

Waterproofing Ceresit is offered for sale in different types. For example, CR 65 is a dry mixture that is resistant to low temperatures, is not exposed to salt and alkali, and is easy to use. Application should be carried out with a brush or spatula. Work can be carried out inside or outside the premises.

The Ceresit waterproofing is also available in the CL 51, which has the appearance of a one-component polymer dispersion and has a high degree of elasticity. Used indoors and great for waterproofing underfloor heating.
