Textured HDPE Geomembrane

By admin on Mar 27 in Geomembrane.

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. Our 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.

Description

HDPE Geommebrane developed and fabricated with either single-sided or double-sided textured surface is called Textured HDPE Geomembrane. Textured HDPE Geomembrane has a rough surface which can highly improve the friction coefficient which fits more suitable for steep slope and vertical engineering design work which maximize the effective volume of geomembrane, they are also processed with smooth edges to allow for high quality thermal fusion welding between adjacent sheets.

BPM textured geomembrane is made of imported raw material with advanced manufacturing equipment and professional production technology and packed in double woven geotextile and strength belt. Our high-density polyethylene textured geomembrane exhibits superior shear strength and the highest multi-axial performance which features superior high shear strength, big friction angles, outstanding elongation and highest interface surface friction coefficient.  Our 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.
