Composite Geomembrane

1.Composite Geomembrane 2.It's a waterproof material composed of geotextile and geomembrane 3.Good flexibility, anti-leakage

It has good flexibility. Apart from geotextile’s isolation, drainage, reinforced, protective functions, it also has closed (impermeable) function.

Product Specification:

1. One piece of geotextile and one piece of membrane; Weight of base geotextile: 100-1000g/m2 ; Thickness of geomembrane: 0.1-1.5mm.

2. Two pieces of geotextiles and one piece of membrane; Weight of base geotextile: 80-600g/m2 ; Thickness of geomembrane: 0.2-1.5mm.

3. One piece of geotextile and two pieces of membranes; Weight of base geotextile: 100-1000g/m2 ; Thickness of geomembrane: 0.1-0.8mm.

4. Multi-layers: Weight of base geotextile: 100-1000g/m2 ; Thickness of geomembrane: 0.1-0.8mm.

Application Field:

Widely used in dam, traffic tunnel, road, airport, drainage, housing, environmental preventing leakage, protection, reinforcement etc.
