Composite Geomembrane

   Composite geomembrane,a waterproof material,compound with geotechnological fabric and geomembrane , it is used for draining off water and adding the muscle mainly. It divides into one cloth one membrane and two cloth first membrane,width 4-6m,weight range is 200-1500g/m2.

  The geomembrane is against drawing, tearing resistance,and high CBR plunger strength, can meet the need of civil engineering such as water conservancy , municipal administration,building,traffic,subway,tunnel etc.Because of selecting high polymer materials for use and adding the aging-resistant materials in the production technology, it can use in the unconventional temperature environment.

PE Geomembrane

Features:
1.All physical factors such as anti-draw, anti-tear, and anti-stab meet the requirement of water works, chemicals, tunnels, and transportation project in most conditions.
2.Good aging, durable performance, and wide temperature arrange, it can be useful over thirty years on the condition of -60æ«60æ.
3.Anti-stab and fine friction factors.
4.Canker proof, acid and alkali proof, untoxic.
5.Lower cost per unit area, cost is 1/3«1/2 lower than that of PVC film, glass and cloth.
6.Convevient to install and dependable effect.
Specification:
Breadth:4-14m Thickness:0.18-1.5mm

PVC Waterproof Material

     PVC waterproof rolls are formed by being added various auxiliary and ageing-resistance agent into chlorine vinyl resin with the one-time forming extrusion press (it is a first in our country) made by our company. It is characterized by high extensibility and elongation, good flexibility at low temperature, good ageing-resistance and long life span.

     Application  scope: Widely used in roof、basement 、railway、tunnels、reservoir、non-ferrous metals and rubbish treatment.
