Geosynthetic Clay Liner

Geosynthetic Clay Liner is also named sodium bentonite composite waterproof pad. This is to make high swelling sodium bentonite filling into the inside between special composite geotextile and non-woven fabric. The bentonite impermeable cushion that made of acupuncture method can form a lot of small fiber spaces. This is to make the bentonite particles cannot flow in one direction. When encountering water, it can form uniformly high density colloidal waterproof layer in the pad, and effectively prevent water leakage. Geosynthetic clay liner is suitable for artificial lake water, landfill, underground garage, roof garden, pool, oil depot and chemicals yard.
