Geosynthetic Nonwoven Composite geomembrane
Product Description
Made by non woven geotextile and PE/PVC geomembrane.
The categories include: geotextile and geomembrane, geomembrane with non woven geotextile on both sides, non woven geotexile with geomembrane on both sides, multi—layer geotextile and geomembrane.
Product Specification
One geotextile and one geotextile, geotextile:100-1000g/㎡, geomembrane 0.1-1.0mm.
Geomembrane with geotexile on both sides: geotextile 100-400g/㎡; geomembrane: 0.2-1.0mm
Geotextile with geomembrane on both sides: geotextile 100-1000g/㎡; geomembrane: 0.1-0.8mm
Product Features
Good flexibility; fine separation, drainage, reinforcement and protection effects; excellent sealing (waterproofing) function.
Application Scenarios
It is an ideal anti-seepage material and is widely used in water conservancy and traffic tunnel projects such as channels, embankments, plain reservoirs, impervious reinforcement of dangerous reservoirs, and anti-seepage of rockfill dams.
