Geotextile membrane is made of plastic film as impervious base material and geotextile impervious material. The new material geomembrane mainly depends on the impermeability of plastic film. Mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), using the ECB design and application in tunnel (ethylene vinyl acetate modified asphalt blending geomembrane), they are a kind of polymer chemistry of flexible material, the proportion of small, strong extensibility, high resistance to deformation. Corrosion resistance, low temperature and frost resistance.
Geotextile membrane is a kind of waterproof barrier material with macromolecule polymer as its basic material. Mainly divided into: low-density polyethylene (LDPE), geomembrane, high-density polyethylene (HDPE), geomembrane and EVA geomembrane.
Feature of geotextile membrane:
1.Width and thickness specification is complete.
2.Excellent environmental stress cracking resistance and excellent chemical corrosion resistance.
3.Excellent chemical corrosion resistance.
4.Hold a larger temperature range and longer service life.
5.Used in landfills, tailings storage, seepage control, dam seepage control and subway works.
