Waterproof methods of old houses and new houses

Cracks in precast slabs of old houses are generally leaking and filled with cement mortar, which has no waterproof effect at all. Even if the existing waterproof material is added to the ceiling, water will still leak out from the side. Unless you waterproof the whole ceiling and wall, this amount of work is called big. In this case, water will enter the wall and will not solve the problem.

Waterproof treatment of new house

The new house must be waterproof before bricklaying, and the floor+wall 30cm high should be coated with waterproof material at least twice. Waterproof materials are generally rubber chemicals with strong smell, and large-area surface treatment is not recommended.
