Application of HDPE Geomembranes

● Landfill lining and capping

● Reservoirs for water and wastewater

● Pond lining

● Irrigation canals

● Manmade lakes

● Oil storage

Advantage of HDPE Geomembranes

◆ Good flexibility.

◆ Service temperature range: -70°C -- +110°C

◆ Corrosion resistance, and aging resistance.

◆ Excellent environmental stress cracking resistance

◆ High tensile strength and elongation.

Reference Standard of HDPE Geomembranes

CJT234-2006

GBT17643-2011

GRI-GM13

Types of HDPE Geomembranes

HDPE Geomembranes are available in three types: Smooth and Textured

Smooth HDPE Geomembrane

Made from high density polyethylene resins, Smooth HDPE Geomembranes are the most widely used products for lining of landfills, mines, reservoirs and other fluid containment applications. They are preferred for sites requiring low permeability and exceptional chemical and ultraviolet resistance properties.

Textured HDPE Geomembrane

Textured HDPE Geomembranes also called Rough HDPE Geomembranes are produced from high density polyethylene (HDPE) resins resulting in a high quality premium grade geomembrane with either single or double textured surface, has been formulated to be chemical resistant, free of leachable additives and resistant to ultraviolet degradation.
