1,Introduction

Compound Geomembrane is made ​​of composite geotextile and geomembrane impermeable material, On one or both sides of the film through the infrared heating oven, the geotextile and the geomembrane from the guide roll to form a geomembrane. With the improvement of the production process, there is a casting method do geomembrane craft. It is mainly used impermeable geomembrane into a cloth membrane and two cloth one membrane, multi-fabric multi-film. To meet the needs of Civil Engineering, irrigation, municipal, construction, transportation, subways, tunnels and so on.

2,Feature

Physical and mechanical properties of tensile strength, tear resistance, bursting and other indicators of high, Compound Geomembrane with high strength, good elongation properties, deformation modulus, acid, corrosion resistance, anti-aging, anti-seepage performance characteristics. To meet irrigation, municipal, construction, transportation, subways, tunnels, construction of seepage, isolation, reinforcement, crack reinforcement, civil engineering needs.

3,Application
