composite geomembrane

Composite geomembranes are made by heat-bonding a nonwoven or woven geotextile to geomembranes.The composite have functions and advantages of both the geotextile and geomembrane.

Composite geomembrane advantages:
1. High tensile strength and modulus
2. Effective drainage and waterproof performance
3. Multi-purpose
4. Easy to build and cost saving
5. Good performance of anti-ageing and anti-freezing
Application:
Composite geomembrane is widely used in dams, traffic tunnel, road, airport, drainage, housing, environmental protection and many other fields for waterproof protection, reinforcement etc.

Explanation

1. Width of product: >5.0m, and thickness of film are 0.2 ~ 0.8 mm.

2. Composite geomembrane can reserve welding border arbitrarily according to the need of the user.

3. The specification that is not in the form can be arranged by user and supplier two sides.

4. Provide special anti-creepage product, such as enhanced type of woven Geocomposite membrane and more textiles with more films.

5. Provide technical consultation and live welding teaching.
