Waterproof coating method
Using special waterproof paint on the wall can effectively prevent the wall from seepage. The main components of waterproof coating are emulsion, pigment, filler and additives. When in use, it is necessary to clean the wall, remove impurities such as oil, dust, etc., and then apply waterproof paint.
Osmotic crystallization method
The penetrant is coated on the wall, so that the penetrant penetrates into the depth of the wall and reacts with cement to generate crystals, thus achieving the purpose of waterproofing.
Silicon dioxide waterproof method
The aqueous solution of silicon dioxide is coated on the wall surface, and a hard hydrophobic film is formed through chemical reaction, which makes the wall waterproof.
Directly buried waterproof method
A layer of waterproof material is laid on the foundation of the building, and polymer composite materials, such as plastic film and cement board, are generally used. This method is suitable for high water pressure of building foundation.
Demolition and reconstruction method
When the water seepage disease of the wall is serious, if the above methods cannot solve the problem, the method of demolition and reconstruction must be adopted. Although this method is expensive, it can completely solve the problem of water seepage.
