Geosynthetic Clay Liners (GCL)
Product Description
GCL is a new type of geosynthetics, which is a compositive impervious material produecd by needling or stitching a layer
of clay or geomembrane,our company adopts the high expansive Na-bentonite , it will expand in the water, forming the
water-proof gel by hydration. At the same time, the bentonite can also store the water.And the water content can reach ten
times as heavy as the bentonite's weight.
