30m Length Geosynthetic Clay Liner Chemicals Resistant For Heap Leach Pads
Geosynthetic clay liner for heap leach pads
Product Description
Geosynthetic clay liners (GCL) are high-performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibers from the non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven). when hydrated under a confining load, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay.
