Bentonite Geosynthetic Clay Liner With HDPE Membrane For Landfill Project
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.
Geosynthetic Clay Liner 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.
1. Applies to new civil engineering planted roof garden, basement,
roof and other water projects; Water projects
2. subway, railway, municipal roads, light industry, petroleum and
metallurgical industries;
3. earthwork repair and reinforcement of anti-seepage project;
4. Desert governance, environmental reform, landfill, artificial
lakes, man-made landscape soil waterproof blanket a large area;
5. 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
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.
