SECTOR SUITABILITY

HDPE Geomembrane
High-Density Polyethylene
HDPE geomembrane liner is the preferred product for lining projects. HDPE liner is resistant to many different solvents and are the most widely used geomembrane liner in the world. Although HDPE geomembrane is less flexible than LLDPE, it provides higher specific strength and can withstand higher temperatures. Its exceptional chemical and ultraviolet resistance properties make it an extremely cost-effective product.
What Makes So Resilient?

Withstands High-Temperature Exposure	Excellent Longevity In Harsh Environments	Wide Format Rolls for Fast Installation
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.

Benefits of HDPE

Applications

· 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.

· Irrigation ponds, canals, ditches & water reservoirs

· Mining heap leach & slag tailing ponds

· Golf course & decorative ponds

· Landfill cells, covers, & caps

· Wastewater lagoons

· Secondary containment cells/systems

· Liquid containment

· Environmental containment

· Soil Remediation
