Water Reservoirs

A Long-Term Solution for Ponds & Reservoirs

The weight and thickness of Geo-Form EPDM Rubber Alloy make it an ideal choice for many ponds and reservoir lining applications.

Remains Flexible

Geo-Form geomembrane is not a semi-crystalline microstructure and is not susceptible to stress cracking; therefore it can be securely welded at temperatures as low as 10 degrees Fahrenheit.

Reduces Damage

When the subgrade shifts and settles or stones protrude into the lining over time, the ductility feature allows the lining to stretch and mold to the changing contour without rupturing.

Weight Matters

The weight of Geo-Form lining is over one half pound per square foot and resists uplifting in winds up to moderate gale-force during installation.

All Reservoir & Pond Linings are Custom Made and Built to Last.
