Compound geomembrane , a waterproof materials , compound with geotechnological fabric and geomembrane , it is used for draining off water and adding the muscle mainly. It divides into one cloth membrane and two cloth one membrane , width is 4-6m; weight is 200-1500g/m2
The geomembrane is against drawing ,tearing resistance , and high CBR plnger strength , can meet the need of civil engineering such as water conservancy , municipal administration , building , traffic , subway , tunnel ect. Because of selecting high polymer matericals for use and adding the aging-resistant materials in the production technology  , it can use in the unconventional temperature environment.
