7.simple construction Product Description 1,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.
2,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.
3,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.
4,GCL is anti-seepage liner between CCL (site tamping clay anti-seepage liner) and macromolecule material earthwork film.
5,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. Characters 1 Good waterproof capacity, sodium bentonite can form a gel layer which does not permit the penetration of water
2. It has strong ability to fit the uneven sedimentation well.
3. Good water-keeping and self-fix capacity
4. Permanent waterproof capacity, sodium bentonite is natural inorganic mineral material, there is no corrosion and age happened to sodium bentonite
5. sodium bentonite is harmless to human being and environment.
6 easy operation, it can be fixed in nail and gasket, it can reduce the building time greatly. Application fields: landfill caps 
base liner applications under roads, railways,
containment for ground tank farms, dams, canals, ponds, rivers and lakes. Data Sheet of GCL (4.2kg Bentonite)
