Bentonite Geosynthetics Clay Liner Waterproofing Gcl
Product Description
Filled between specially made composite geotextiles and non-woven fabrics with high expansion sodium based bentonite, the bentonite anti-seepage pad made by needle punching method can form many small fiber spaces, preventing bentonite particles from flowing in one direction. When encountering water, a uniform and high-density adhesive like waterproof layer is formed inside the pad, effectively preventing water leakage.
