Water Conservancy Project Bentonite Geosynthetic Clay Liner 30m Length
Water Conservancy Project Bentonite Geosynthetic Clay Liner
Product Description
Bentonite waterproof blanket is a geosynthetic material specifically used for preventing leakage in artificial lakes, landfills, underground garages, rooftop gardens, water tanks, oil depots, and chemical storage yards. It is filled with highly expansive sodium based bentonite between specially made composite geotextiles and non-woven fabrics. The bentonite anti-seepage pad made by needle punching can form many small fiber spaces, making it difficult for bentonite particles to flow in one direction, When encountering water, a uniform high-density adhesive waterproof layer is formed inside the pad, effectively preventing water leakage.
