Installation & Benefits

• Rollgum's EPDM liner is extremely easy to work with, making it adaptable to any dam size or shape, regardless of the complexity. The high elasticity of the membrane makes the rubber liner easy to stretch and bend while remaining tough and durable. The liner is also easy to cut and join together using Rollgum bonding adhesive, tape and sealants.

• Unlike many other EPDM liners, Rollgum doesn’t require you to scrub off powdery mica with a scouring pad before joining. Thanks to Rollgum’s modern, mica-free manufacturing process, it’s cleaner for the environment and far easier to install. You can simply apply the primer with a paintbrush — no heavy scrubbing or extra prep required. This not only saves time but also reduces the risk of weak joins caused by incomplete cleaning, making installation smoother and more reliable. Plus, you won’t get white floating mica in your dam, the moment you start filling it with water.

• With the capacity for large, seamless roll widths, installation in larger dams is simpler, reducing the number of seams and potential failure points.

Recommended–Use an Underlay

For the best protection and longevity, we strongly recommend using a liner underlay, available from Love My Dam. The underlay provides a protective cushion between the liner and the ground, reducing the risk of punctures from rocks, roots, or sharp debris. It also improves installation quality and extends the lifespan of your EPDM liner.

About Rollgum

In 1969 Joan Palou started a waterproofing company in Díaz, Spain. Early in his entrepreneurial journey he met Michel De Knop, the Managing Director of Firestone's European operations. This led to a thriving alliance and the first EPDM liner being installed in Spanish reservoirs in the 1970s. This liner, installed over 50 years ago, continues to hold its shape, quality and look to this day. Today, Rollgum is led by Joan Palou (son) who continues his father’s legacy, producing the highest quality EPDM liner from Rollgum's manufacturing facilities in Barcelona, Spain.

What is EPDM liner?

EPDM liner is made of tough synthetic rubber that looks great in the wild and holds its shape and feel for a lifetime. Unlike plastic liners that bubble, ridge and deteriorate over time, EPDM liner provides a smooth, natural-ish look that doesn’t fade or lose quality, even after decades of exposure to the harsh Aussie sun.

EPDM liner is made of rubber meaning, unlike plastic, it doesn’t leach nasty chemicals into your water or surrounding environment. It also isn’t attacked by microbial organisms, a common occurrence in plastic which deteriorates the liner. This makes EPDM liners the most ideal choice for swimming holes, fishing dams, any water bodies used by people or animals.

With high-grade UV protection, EPDM liner holds its look and strength. The liner is designed to maintain its look (not fade) and quality in extreme temperatures ranging from well below -40°C to well above 50°C. This is not the case with plastic liners which become brittle in the cold and stretch in the heat. Rollgum EPDM liner also offers unrivalled flexibility while remaining strong and durable. The elasticity of the rubber (up to 400% stretch) is retained even at temperatures well below 0°C. This means you can easily manipulate the membrane to support all shapes and sizes of ponds and dams. You can also stretch and move the liner, even after decades of use.
