Description

Geosynthetic Clay Liners (GCL) are high performance needle punched enbironmental reinforced composites which combine two duiable geotextile outer layers with a uniform core of natural soidum bentonite clay to form a hydraulic ***** from the non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile. When hydrated under a confining load, the bentonite swells to form a low permeability clay layer with the equbalent hydraulic peojection of several feet of compacted ***** excellent properties make the products ideal for many projects. Features: GCL is Natural Material, well duiability, non-toxicity, no corrosion, and it won&#**9;t be aging. High expansion rate, high water absorbing capacity, low specific water conductivity. High filter rate, it can self-repair invisible leaks by moving of bentonite. Construction simple and quick, low requirement of surface ***** can be cutted and layed as your ***** can use it, don&#**9;t need any professionals and professional construction machinery.
