What Makes EPDM Different?

EPDM fills a unique niche in the geomembrane family — offering unmatched flexibility, ease of installation, and cold-temperature performance that other materials cannot match.

Easiest to Install

Unlike HDPE or LLDPE, EPDM can be installed using a knife and caulking gun — no specialized welding equipment or certified technicians required for standard applications.

Performs in Extreme Cold

EPDM retains its rubber-like flexibility even in extreme winter conditions down to -50°C, making it the only viable option for northern climate year-round installations.

Industry's Strongest Warranty

AWTT EPDM liners carry a 25-year warranty — the strongest product warranty in the geomembrane industry, reflecting the material's proven long-term performance.

Conforms to Irregular Subgrades

EPDM's exceptional elongation characteristics allow it to conform naturally to subgrade irregularities without bridging, eliminating stress points that can cause failures.

EPDM Liner Applications

EPDM's unique properties make it the material of choice for exposed applications, sub-zero environments, and projects where non-professional installation is required.

Irrigation Ponds & Canals

Flexible liner that conforms to irregular canal shapes and pond contours without bridging or wrinkling.

Water Reservoirs

UV-stable exposed lining for drinking water and agricultural water storage reservoirs.

Agricultural Containment

Ideal for farm ponds, irrigation ditches, and agricultural water management systems.

Golf Course & Decorative Ponds

Easy DIY-friendly installation makes EPDM a popular choice for landscape and golf course water features.

Earthen Dam Liners

Excellent impervious liner layer for earth-filled dams — flexible enough to handle settlement without cracking.

Sub-Zero Applications

The only geomembrane that retains full rubber-like flexibility even in extreme -50°C winter conditions.
