Hdpe Textured Geomembrane

Textured HDPE Geomembrane Introduction


Textured Geomembrane has either single-sided or double-sided textured surface which is made of imported raw material with advanced manufacturing equipment and professional production technology and packed in double woven geotextile and strength belt. WT Brand Textured HDPE Geomembrane is widely applied for such projects which need increased frictional performance, flexibility and elongation between two layers and high steeper slopes as landfills, mining, retaining backfills and waste containment.
