comparing with geotechnical film, its advantages are mainly shown as following:

1.It has good tightness, water proof and water isolation performances, bentonite forms dense and non-permeation gel isolation film layer of bentonite under normal water pressure status.

2.It has long waterproof capacity; bentonite is natural inorganic mine material and will not have corrosion and aging phenomena.

Features:

The geosynthetic clay liner(GCL)we made ,have three layers for needle punched, upper layer is needle punched PP non-woven geo textile, the inside is natural sodium bentonite and bottom is woven geotextile and needle punched together, it has higher waterproof capability for construction, landfill, man-made lake and other projects, our product is warmly welcomed by international customers! we provide professional waterproof technique team and competitive price and best service for you! our sample for 4.5KG is as following:
