Product Description

Geosynthetic Clay Liner (GCL) with Sodium Bentonite

Description of GCL 
Geosynthetic clay liner with PE Geomembrane 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 geotextile).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.

Sodium bentonite granule consists of natural clay inorganic mineral materials processed with high expansion and high water absorption capacity, low permeability when wet performance, mainly for waterproofing.

Property  
Geosynthetic Clay Liner compared with the compacted clay liner, it is small, light weight, good flexibility, good seal, shear strength, simple construction, differential settlement of the advantages of adaptation.

Application
Geosynthetic clay liner mainly used in environmental engineering of landfill emissions, underground reservoirs, underground infrastructure constriction projects, sealing solution, segregation, anti-leakage, good effect, anti-destructive.
Applies to new civil engineering planted roof garden, basement, roof and other water projects; Water projects
subway, railway, municipal roads, light industry, petroleum and metallurgical industries;
earthwork repair and reinforcement of anti-seepage project;
Desert governance, environmental reform, landfill, artificial lakes, man-made landscape soil waterproof blanket a large area;
water conservancy projects was even better, in a large area of water seepage construction of buildings, small Reservoir, dam, irrigation canals, reservoirs ponds, etc. can have a wide range of applications.
