Product Details
Geosynthetics Clay Liner (GCL)
Geosynthetics Clay Liner is a kind of geosynthetic material specially used for preventing seepage of artificial lakes, waterscapes, landfills, underground garages, roof gardens, swimming pools, oil depots and chemical storage yards. It is made of highly expansive sodium-based bentonite which is filled between special composite woven geotextile and non-woven geotextile. Bentonite impermeable pad made by needle-punching can form many small fiber gaps. Bentonite particles cannot flow in one direction and stay in the pad when they meet water. A uniform and high-density colloidal impermeable layer is formed to effectively prevent water leakage.
Could be manufactured according to your inquiry, MINIMUM ORDER QUANTITY: 20ft container
