Bentonite Waterproof Pad (GCL)

Bentonite waterproof pad (GCL) is a new type of geosynthetics,after evenly mixing with the natural Na-bentonite particles and the additives through a special process and equipment, relying on the strength of the tens of thousands of fibers firmly fixes highly expansive Na-bentonite layer between two layers of geotextile evenly, it takes sealed, isolated, enhanced and excellent waterproof (anti-leakage) performance. The Pad we provide accords with American Standard,its quality(including bentonite,geotextile etc.)takes credit ,please see the belowed.
