Textured HDPE Geomembrane

Textured HDPE geomembrane has increased friction coefficient and anti-slip function, which is more suitable for steep slopes and vertical seepage prevention, and improves engineering stability.

Textured Geomembrane Description

Textured HDPE Geommebrane is designed and fabricated with either single-sided or double-sided textured surface improve friction between two layers. 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.

TINM textured HDPE 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

Types of textured geomembranes

Textured HDPE geomembrane is roughly divided into four categories, namely single rough surface geomembrane, double rough surface geomembrane, single column point geomembrane, double column point geomembrane,
According to different production processes, it can be divided into nitrogen roughening geomembrane, spray roughening geomembrane and column point type geomembrane.
