Features :

1. The permanent waterproof

Because sodium base bentonite is a natural inorganic material, even after a long time or the surrounding environment changes, also won't happen aging or corrosion phenomena, so the waterproof performance persistence.

2. Compactibility

Sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm, its permeability is5*11m/SEC below, equivalent to 100 times the compactness of 30 cm thickness of clay.

3. Environmental protection Bentonite as natural inorganic material, nontoxic harmless to human body, no special effects to the environment, have good environmental performance.

4. Simple and short time of constructionCompared to other waterproofing materials, construction is relatively simple, don't need to be heated and paste. With bentonite powder and nails, washers, etc are connected and fixed.

GCL Application :

Waste landfill capping and cutoff walls to contain pollution,mining base seals, canal and dam liners, lakes and other waterproofing projects.
