4000g GCL Hardening Bentonite Geosynthetic Clay Liner
4000g GCL Hardening Bentonite Geosynthetic Clay Liner
Product Description
GCL sodium bentonite geosynthetic clay liner is a new type of geosynthetic material, and it can be divided into needle-punctured GCL(GCL-NP) and needle-punctured coated GCL(GCL-OF). GCL is a kind of bentonite seepage-proofing mat needle-punctured through filling sodium bentonite between woven geotextile and non-woven geotextile. Among which tiny fiber spaces can be formed to prevent bentonite particles to move to a direction. It can form glue-type water-proofing layer to prevent water leakage. Woven geotextile of 120g/㎡ and non-woven geotextile of 220g/㎡ are applied in this kind of GCL.
