Geosynthetic clay liner
Zhongloo
Product Description
Geosynthetic Clay Liner(GCL) 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.

GCL Feature:
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 is 5 x 10-11 m/SEC below, equivalent to 100 times the compactness of 30 cm thickness of clay,
have very strong since the water retention performance.
3.Not affected by temperature
In cold climates will not brittle fracture.
