It is recommended that you use polymer (polypropylene cloth) waterproofing membrane. It is also a cheap waterproof material with good waterproof effect. It is non-toxic, tasteless, pollution-free and safe to make two layers to achieve the best effect.

The construction methods of waterproof main and auxiliary materials are as follows:

1. Proportion of mucilage: weight ratio of cement to special rubber powder 100 (cement): 1 (rubber powder): 50 (water) (appropriate amount of water).

2. Proportioning method: first put the rubber powder into a container, then add cement and stir it. After mixing evenly, add water and stir it into a paste-like fluid before use.

3. Play the baseline on the construction base and adjust the coil paving.

4. There must be no open water on the base surface. If it is very dry, it is necessary to spray water on the surface of the base surface to keep warm.

5. The ground and coil coating should be uniform and consistent, and should not be missed. After straightening, it should be compacted and leveled.

6. Make a one-component polyurethane edge sealing at the joint sealing.
