Bentonite Waterproofing Blanket Geosynthetic Clay Liner Gcl for Landfills
Geosynthetic clay liner is a geosynthetic material specially used for anti-seepage of artificial lake water features, landfills, underground garages roof gardens, pools, oil depots and chemical storage yards. It is made of highly expansive sodium Base bentonite is filled between the special composite geotextile and non-woven fabric, and the bentonite anti.seepage pad made by acupuncture method can form many small fiber spaces, because the bentonite particles cannot flow in one direction and form in the pad when they meet water Uniform high-density colloidal waterproof layer, effectively prevent water leakage.

1. Good waterproof capacity, sodium bentonite can form a gel layer which does not permit the penetration of water.
2. It has strong ability to fit the uneven sedimentation well.
3. Good water-keeping and self-fix capacity.
4. Permanent waterproof capacity, sodium bentonite is natural inorganic mineral material, there is no corrosion and age happened to sodium bentonite.
5. Sodium bentonite is harmless to human being and environment.
6. Easy operation, it can be fixed in nail and gasket, it can reduce the building time greatly.
Application
It is suitable for municipal (garbage landfill), water conservancy, environmental protection, artificial lakes and underground waterproofing and anti-seepage projects of buildings. Compared 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. After construction does not need specialinspection, if it is found that the waterproof defects and easy to maintenance. GCL is existing waterproof material in construction period of the shortest.
