When laying the foundation, materials that are not resistant to moisture are often used. They need to be waterproofed. Waterproofing technology is also suitable for other types of buildings. Often, I use coatings for external protection against moisture penetration in fireplaces, brick barbecues of special masonry and swimming pools..
On specialized sites, you can learn how to make a brick brazier.
The waterproofing of its foundation is very important for how long the whole house will last. The underground part of the foundation waterproofing is provided by a drainage system, which includes vertical, horizontal waterproofing and drainage.
Horizontal waterproofing is made of rolls of waterproofing material (Technoelast, Aquaizol lining, Bipol, etc.) and is laid above the blind area of the house, at the level of the bottom of the basement overlap. Usually two or three layers of insulating material are 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, pasting, and screen waterproofing.
• Lubricating waterproofing is a mastic with a cement-polymer composition with the addition of bitumen-rubber and bitumen-polymer mixtures. Bitumen should not be used for this purpose — it quickly loses its elasticity and cracks.
• Adhesive waterproofing — usually sold in the form of a film, in rolls. They are glued with the help of special waterproof mastics on the outer sides of the foundation. This type of insulation requires additional leveling and priming, but it is distinguished by good waterproofness, durability and resistance to various influences..
• Penetrating waterproofing — cement mixtures that are applied to the outside and inside of the foundation. Active additives and fine-grained quartz sand, entering into a chemical reaction with concrete and crystallizing on its surface, thus clogging all pores and cracks in the world.
• Screen waterproofing — bentonite clay panels, geotextile membranes and a pressure wall made of bricks, etc. Screen waterproofing is used in extreme conditions, for example, the impact of groundwater under pressure
