Description
Introduction:
The composite geomembrane is a kind of geosynthetics which made of more than two kinds of materials such as geotextiles (or fiber glass mesh), polymers (such as PE geomembrane, EVA geomembrane) and so on. It uses the geotextile as hydraulic conductivity layer, the geomembrane as impermeable layer, made of composite geomembrane with rolling or casting extrusion and hot melt.It have functions and advantages of both geotextile and geomembrane.
Products type:
- One geotextile one geomembrane;
- Two geotextiles one geomembrane;
- One geotextile two geomembrane;
- Two geotextiles two geomembrane.
Features:
- High tensile strength and modulus
- Effective drainage and waterproof performance
- Multi-purpose
- Easy to build and cost saving
- Good performance of anti-ageing and anti-freezing
Application: It can be widely used in areas of garbage burying, waste disposal, tail minerals storage and underground construction projects
