The advantages of Liufangzi GCL

1. Environment friendly

Liu Fangzi GCL is made of natural raw materials of sodium-bentonite. It is raw and natural materials,; aging and corrosion seldom happen. It can keep its quality and then it does not cause any injuries and pollution for human and the environment. It is not only waterproof, but also has good ventilation performance. It can stick up for the exchange of the ecological environment. It is a pure natural, new, green waterproof material

2. Permanent waterproof, excellent performance

Natural sodium bentonite was formed billions of years ago.

Its waterproof properties are much more durable than that of the buildings. Sodium bentonite would transform to high density septum under hydro pressure.

3. Easy to construct

Bentonite powder, nails and washers are enough for connection and fixation. Construction is not constrained by weather conditions and it could be taken under cold or wet conditions. Bentonite powder is spread on overlap point.

4. Strong Self-Restore Capacity

The integration between waterproof material and its target enables GCL a 20~28 times swelling volume. Even if concrete structure trembles or subsides, the bentonite in GCL would restore the crack of 2mm or below on the concrete structure immediately. Even if the diameter of perforation reaches 30 mm, the restoration will be finished within 15 days completely.
