HDPE Geomembrane Liners for Water Storage & Containment
High-Density Polyethylene (HDPE) geomembrane liner is the preferred product for lining projects worldwide. The most chemically resistant geomembrane available — UV-stable, field-welded, and proven in the most demanding industrial applications.

Stable — No Cover Needed
Industry Standard
Most Chemically Resistant
HDPE Liner Thickness Options
Available from 20 to 120 mil. The correct thickness depends on subgrade conditions, chemical exposure, stress loads, and project lifespan requirements.
40 Mil HDPE
Requires excellent subgrade conditions. Preferred upgrade from 20 mil RPE for larger installations where subgrade is well-prepared and stable.
Common Applications
Irrigation ponds, golf course ponds, agricultural applications
60 Mil HDPE
Industry standard for most applications. Provides the optimal balance of flexibility, strength, and cost-effectiveness for general industrial containment.
Common Applications
Water reservoirs, wastewater lagoons, secondary containment
80 Mil HDPE
Thicker design specified for aggressive subgrades, high-stress applications, or projects requiring additional puncture and abrasion resistance.
Common Applications
Mining heap leach, landfill liners, aggressive chemical containment
Why HDPE Is the Global Standard
HDPE geomembrane dominates global containment projects because of its unmatched combination of chemical resistance, UV stability, and weld integrity.
Most Chemically Resistant
The most chemically resistant member of the polyethylene family due to its dense molecular configuration — resists a wider range of chemicals than any other geomembrane.
Factory-Quality Field Welds
Field-welded with hot wedge and extrusion welders. These welds achieve factory-quality seams that are virtually stronger than the sheet itself — eliminating weak points.
UV Stable — No Cover Needed
HDPE is UV-stable, eliminating the cost of covering or backfilling over the liner. This makes it significantly more cost-effective than UV-sensitive alternatives for exposed applications.
Widest Thickness Range
Available from 20 to 120 mil, offering precise specification for every project size and stress condition — from small agricultural ponds to major industrial containment systems.
