Bentonite Waterproof Pad GCL Geosynthetic Clay Liners With HDPE Geomembrane
Geosynthetic Clay Liner Description
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.
Geosynthetic Clay Liner 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.
