Why do I need waterproofing?
Waterproofing penetrant provides waterproof concrete structures. This group includes the compositions necessary to protect the porous material from absorbing moisture. The principle of operation is based on the penetration of the insulating material into the upper porous layer, which is insoluble. It fills all pores and displaces liquid. The introduction of a special component in the solution makes it possible to carry out various modifications of the properties of the material being processed. For example:
- Prevents corrosion on the reinforcement of the reinforced concrete base;
- Restores the technical properties of old concrete;
- Struggles with the appearance of fungus and mold;
- Increases the chemical resistance of the material.
Such materials are used, both in the beginning of construction, and during repair and restoration of structures. Often they are used for waterproofing in buildings that are already in operation. The material perfectly holds the back pressure, which allows it to be used successfully for application from the inside. Crystalline waterproofing formations overlap the moisture path deep into the concrete and, at the same time, do not block the free movement of air, allowing it to "breathe".Penetrating waterproofing of the foundation allows the base to perfectly resist the aggressive influences of the environment.
Tip! In the process of construction or repair, make sure that the foundation is waterproofed.
Injection waterproofing and its types
The type of penetrating insulation is injection waterproofing( liquid), which is necessary for reliable protection of the treated surface from the harmful effect of moisture. It has good technical qualities and durability. Liquid waterproofing produces protection not only from moisture, but also from changes in temperature, corrosion and maintain heat in the room. In general, liquid rubber or liquid glass acts as an injection waterproofing.
Liquid rubber has the following qualities:
- High flexibility and elasticity;
- Easy to apply;
- Ecological cleanliness;
- Has good adhesion;
- Easily repaired.
It is applied by special equipment, and the process does not require special skills, it is necessary to distribute the material evenly. Actively used for the treatment of roofing, tunnels, sewerage, swimming pools. The surface of the applied waterproofing is smooth and smooth, the seams on it are absent.
Liquid glass is a solution of potassium and sodium silicate. It is made into concrete, which makes its performance better:
- Becomes more solid;
- Best resistance to mechanical damage;
- The level of moisture absorption decreases.
There is no need to use any equipment for its use. You just need to stick to the proportions, mixing concrete and water glass. You can also use it in its pure form. The liquid glass protects against corrosion and destruction from wind, temperature, sun and so on.
Tip! The liquid glass protects the surface for five years. At the end of this time, the waterproofing procedure is repeated.
Contraindications to use
Injection materials, like any other kind, have their contraindications and recommendations for use. To adhere to these recommendations is necessary to ensure that the quality of all the work performed was at a high level and provided a reliable and durable protection. Consider these rules:
- If the temperature is below 5 degrees and the next 24 hours are expected to freeze, the waterproofing must not be applied;
- Do not apply to frosty or ice-covered surfaces;
- Wet the surface thoroughly, but never allow the formation of puddles;
- Do not apply limestone to gypsum.
Important! All work with the material must be carried out in rubber gloves.
Penetrating waterproofing for masonry and foundation is an important material in construction and repair. Whichever type of insulation you choose, it should be remembered that only by adhering to all rules and norms, one can count on successful and high-quality work. No material, no matter how good it is, will not give high-quality protection of the foundation or walls, if the waterproofing was applied in violation of the technological process.
