Geosynthetic Clay Liner (GCL) for landfill and basement lining
Product Description
Geosynthetic Clay Liners is suitable for seepage prevention and waterproof treatment of structures with water storage characteristics such as artificial lakes, reservoirs, large swimming pools, fish farms, channels, garbage disposal yards, etc. Our bentonite clay liner is also applicable to high pressures in buildings, such as basements and tunnels, and impervious and waterproof constructions of buildings in areas with large temperature differences, like seepage prevention, sealing and isolation of subways, pools, and diversion channels.
