1. Produced excellent constructions function
2. Mass per square meter: 400g-1000g.
3. Width3m-6m, thickness0.2-0.8mm
The characteristics:
With the widest width of 6 meters, compared with the other similar products, it can reduce the Engineering cost, the length of juncture and Shorten the construction period. It improved the using effects and saved the time to compared with the traditional construction method which to separate the geotextile and geomembrane for construction.With excellent ageing resistance strength, its Service life will last longer if it is buried underground. have unique functions for Insulation, moisturizing, Frost prevention and antifreezeSuperior in Resistance to both low and high temperature performance, cold heat area is all applicable. And it is nontoxicity with excellent flat drainage and leakage.
The application scope:
Railways, highways, Sport stadiums, dams, construction of hydraulic Tunnel, coastal beaches, reclamation and environmental protection projects.
The constitution of composite geomembrane:
The species of base geotextile: short fiber needle punched geotextile, woven geotextile, Fiberglass Mesh, etc.The material can be choosing according to the customer’s actual demand.
