Impervious Geo-textile
Overview
Impervious Geotextile is mainly use for the soft soil improvement project, which is mainly for soil reinforcement, and soil stability.
Composite Geomembrane is composited by filament geotextile and PE film by hot compound. Excellent for flat drainage and anti-seepage property. It can be applied under unconventional temperature surroundings because it is made of High Polymer Material and aging proof material.
Composite geomembrane is widely applied in water conservancy projects, building, transportation, subway, tunnel, constructions etc.
Performance
a. High Tensile Strength, Tear Resistance;
b. High Bursting S·trength;
c. Good Elongation Properties, Deformation Modulus
d .Anti-Acid, Anti-Corrosion resistance, Anti-Aging, Anti-Seepage
Application
a. Earthwork dam, rock-fill dam, masonry dam and concrete dam;
b. Horizontal impervious blanket of embankment, vertical Impervious barrier of foundation;
c. Tailing dam, dam body and reservoir region of sewage reservoir;
d. Construction cofferdam, canal, liquid bath (pit, coffin pit);
e. Waste storage, seepage control lining for subway, basement and tunnel, roadbed of speedway and railway;
f. Salting prevention of roadbed and other foundation, waterproof of swelling soil and collapsible losses, roofing leak resistance;
