Geosynthetic clay liner
 bentonite waterproof blanket (gcl) is earthwork composite material that is specially used for anti-seepage of man-made lake waterscape, landfill yard, underground garage, building roof garden, water tank, oil depot and chemical pile yard
 what is gcl?
 gcl is blanket shape fabric that is produced by filling sodium base bentonite with high expansion between special composite earthwork cloth and non-woven cloth and locking bentonite on lower composite fabric through upper non-woven cloth fabric by special needle embroidering method. Bentonite anti-seepage liner produced by needle embroidering method can form many small fiber spaces, which prevent bentonite particles from moving in one direction, rubber head water layer with uniform high density is formed in the liner when meeting water so as to prevent water seepage effectively.
 
Product application
 
It is mainly used in various environmental protection projects such as waste landfill yard, underground reservoir and underground infrastructure, solves sealing, isolation and anti-seepage problems, and has good effect and strong damage resistance

4- glass industry to easily remove the gases.
