Compound Geomembrane

Compound Geomembrance 1.Compound materials, with fiber geotextile and geomenbrance 2.Excellent unpermeability 3.Two types

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.

Functions: Isolation and anti seepage 

Applications:

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.
