HDPE Single-sided Textured geomembranes

Textured HDPE Geomembrane is designed and fabricated with either single-sided or double-sided textured surface. Textured 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 proceesed with smooth edges to allow for high quality thermal fusion welding between adjacent sheets.   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.

Typical HDPE materials are unsuitable for extended periods above 60°C [140°F].  We can withstand continuous use at 85°C [185°F] for over 20 years.

· Chlorine resistant (70% HPOIT retained after one year) · UV stable (80% HPOIT retained 1600 hours QUV) · Brine resistant (70% HPOIT retained after one year at 100 deg C)

Fewer seam welding requirements makes for a quicker installation and lower instances of possible failure.

· The most chemically resistant member of the polyethylene family due to its dense configuration.
· Field welded with hot wedge welders and extrusion welders. · These factory quality welds are virtually stronger than the sheet itself. · The best QC-QA testing capabilities in the marketplace. · No need to cover the liner because it is UV stable = cost-effective. · Available in roll stock and come in varying thicknesses ranging from 0.75 to 3.0mm depending on your requirements.
