Geosynthetic clay liner
Zhongloo
Product Description
GCL is a geosynthetic material specially used for anti-seepage in artificial lakes, waterscapes, landfills, underground garages,roof gardens, pools, oil depots and chemical storage yards. It is made of highly expansive sodium bentonite Filled between a special composite geotextile and a non-woven fabric, the bentonite impermeable mat made by needle punching can form many small fiber spaces.
