Composite geomembrane is geosynthetics combined by more than two materials. Fabric acts as water guider layer, while synthetic polymers act as impervious layer.
base fabric types: needle punched short geotextile, woven geotextile, non-woven geotextile, fiberglass meshmembrane material(synthetic polymers): HDPE, LDPE, CPE, EVA, PVC etc.process: curtain coating and thermal compounds, which is the most advanced in Chinacharacter
1) max width is 6m, compared to narrow film, it reduce seams and cost, shorten manufacture schedule.
2) composite geotextile makes better using effects, saves more project time, reduces more cost, compared with separate traditional cloth and membrane.
3) Better aging resistance. Working life will be longer if buried.
4) Excellent resistance to water drainage performance
5) Better aging resistance, great temperature range
6) High puncture resistance, high friction coefficient
7)Used in water conservancy, chemical, construction, transportation, subway, tunnel, landfill and other projects.
