Geomembrane Composite

Introduction

The composite geomembrane is consisted by layers of geomembrane and geotextile fabrics. By adding them together, it becomes more sustainable and durable. It has good flexibility, in addition to the geotextile isolation, drainage, reinforcement, protection and other functions, but also has closed (anti-seepage) function.

Application

It is widely used in water conservancy dam, traffic tunnel, road construction, airport, drainage, housing, environmental protection and many other fields, in the project, mainly plays a turning over, protection, reinforcement and other functions.
