Types of waterproofing of the foundation of the house.

When laying the foundation, materials are often used that are unstable to moisture. For them, it is necessary to do waterproofing.Waterproofing technology is also suitable for other types of buildings. Often, I use coatings for external protection against moisture penetration into fireplaces, brick barbecues of special masonry and pools.

Very large importance of how much the whole house will last as a whole is the waterproofing of its foundation. The underground part of the waterproofing of the foundation is provided by the drainage system, it includes vertical, horizontal waterproofing and drainage.

Horizontal waterproofing is made of rolls of waterproofing material (technoelast, lining aquaizole, bipol, etc.) and fits above the blind area at the house, at the bottom of the basement ceiling. Two or three layers of insulating material are usually laid. In houses without a basement, only horizontal waterproofing is usually done.

Vertical waterproofing is used on the external and internal surfaces of the foundation. There is a coating, penetrating, glow, and screen waterproofing.

• coating waterproofing is a mastic having a cement-polymer composition with the addition of a mixture of bitumen-response and bitumen-polymeric. Bitumen should not be used for this purpose – it quickly loses elasticity and cracks.

• Bulletin waterproofing – usually sold in the form of a film, rolls. Glued using special waterproof mastics on the outer sides of the foundation. This type of isolation requires additional work on leveling and primer, but is characterized by good water resistance, durability and resistance to various influences.

• penetrating waterproofing – cement mixtures that are applied to the outer and inside of the foundation. Active additives and fine -grained quartz sand, entering into a chemical reaction with concrete and crystallizes on its surface, thus clogging all pores and world bonds.

• screen waterproofing – panels made of concrete clay, membranes geotextile and clamping wall made of brick and. The screen waterproofing is used in extreme conditions, for example, the effects of groundwater under pressure
