Composite Geomembrane
Non-woven geotextile is used as the substrate, and polyethylene, polyvinyl chloride and other materials are used asthe membrane. The composite geotextile of the non-woven fabric, has one fabric with one membrane,two fabric with one membrane, two menbrane with one fabric ect.
Thickness: 0.3-3mm;
Width: 4-8m size in accordance to person requirements.
Product specifications:
One layer fabric with one layer membrane: fabric uint weight100~800gsm, membrane thickness: 0.l~l.0m
Two laver fabric with one laver membrane: fabric uint weiht 100~400gsm.membrane thickness: 0.2~1.0mm
One layer fabric with two layer membrane: fabric uint weight 100~800gsm , membrane thickness: 0.1~0.8mm
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.
