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.
