Geosynthetics Clay Liner (GCL)

GCL

Geonets are among the most proven geosynthetics drainage systems. Manufactured from two, or three strands of extruded hdpe which are overlayed across each other, this material forms a void within which water can be transmitted and reduces pore water pressure.
GeofanNet loses little drainage capacity when put under pressure or normal loading.

The Geosynthetics Clay Liner is a kind of geosynthetic material specially used for anti-seepage of artificial lakes, waterscapes, landfills, underground garages, roof gardens, pools, oil depots and chemical storage yards. It is made of highly expansive sodium-based bentonite is filled between the special composite woven geotextile and non-woven geotextile. The bentonite impermeable pad made by needle punching can form many small fiber spaces. The bentonite particles cannot flow in one direction, and they stay in the pad when it meets water. A uniform and high-density colloidal waterproof layer is formed to effectively prevent water leakage.
