 Compound geomembrane

Material:PE/PET/PP 

Specification

1. One piece of geotextile and one piece of geomembrane, unit weight of the fabric: 100-1000g/m2 and film thickness: 0.1-1.5mm

2. Two pieces of geotextiles and one piece of film,  unit weight of the fabric: 80-600g/m2 and film thickness: 0.2-1.5mm

3.  One piece of geotextile and two pieces of geomembrane, unit weight of the fabric: 100-1000g/m2 and film thickness: 0.1-0.8mm

4.   Multi-layers, unit weight of the fabric: 100-1000g/m2 and film thickness: 0.1-0.8mm

Properties

Have puncture resistance,  good flexibility and impermeability in addition to the effectiveness of  isolation, drainage, reinforcement, protection of the geotextile.

Usage

Widely used in dam, traffic tunnel, road, airport, drainage, housing, environmental protection and many other fields for seepage control, maintenance and reinforcement.
