Geomembrance
1. Made of geotextile andf membrance;
2. Excellent impermeability;
3. Isolation and anti seepage;
4. Two types.
Geomembrance
Introduction:
1. Composite Material, composed with short fiber geotextile and geo-membrane (PE or PVC);
2. Excellent impermeable ability because of high polymer materials;
3. Two types:
The two-geotextile one-membrane type and the one-geotextile one-geo-membrane type
Features:
1. Good impermeable ability, used in draining and strengthening pavement;
2. Used in unconventional-temperature environment also allowed;
3. Tensile property, tear resistant, aging resistant and seepage proofing and isolation
Function:
Isolation and anti seepage
Application:
Widely used in subways, basements, and tunnels; roadbeds of roads, highways, and railways; salting prevention of roadbeds and other ground bases; water barriers of expansive soils and collapsible.
