Introduction

HDPE Geomembrane is flexible waterproof and impermeable membrane manufactured from high density polyethylene resin,antioxidant and carbon black mixture.Geomembrane has durable properties against chemicals,biological and mechanical impacts and ultra-violet radiations.HDPE Geomembrane is producing in two versions as smooth surface and textured surface types.

Properties Of HDPE Geomembrane

 *High tensile strength and chemical resistance

*UV resistance and temperature tolerance

*Low permeability and leak prevention

*Flexibility and seamability

*Long service life and minimal maintenance

*Recyclability and safe for the environment

*Wide range of applications and customizable solutions

Advantages Of HDPE Geomembrane

*It is durable by virtue of the special resin comprising of antioxidant and carbon black mixture

*It features high resistance and elongation values

*It is resistant against chemical impacts

*It features high UV resistance by virtue of the carbon black content

*By virtue of the special welding method,it enables performance of air pressure,abrasion and peeling tests from its joints

*The large roll size enables rapid and practical implementation opportunity for large-scale projects

*It is applicable at high oblique areas with products having rough surfaces on single side or both sides

*Materials with lower density(LLDPE,VLDPE)can also be produced for utilization options at different applications

Application Of HDPE Geomembrane

*Soild waste storage yards

*Mining waste deposit yards

*Acid pools

*Luquid product storage tank farms

*Wastewater treatment plants

*Swimming pools

*Lagoons and landscaping lakes

*Cut and cover tunnel walls
