Composite Geomembrane Composite Geomembrane


Features: good flexibility, in addition to the role of geotextile isolation, drainage reinforcement, protection, etc.there is also a closed (anti-seepage)function.

Application : lt is an ideal anti-seepage material, which is widely used in water conservancy and trafic tunnel projects such as channels.guarding, plain reservoirs, anti-seepage reinforcement of reservoirs and anti-seepage of rockfill dams.
