Bentonite Waterproof Blanket Earthwork for Landfill GCL
Product Introduction
Geosynthetic clay liner 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.
Compared with the compacted clay liner, this product has the advantages of small volume, light weight, good flexibility, good sealing performance, high shear strength, convenient construction, to adapt to the advantages of uneven settlement and etc.
