Geomembrance

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.
