EPDM is a synthetic rubber, highly flexible stable material that is not only easy to work with but long-lasting and aquatic safe. We offer Firestone PondGard, a name brand pond liner. EPDM is a highly stable material that is formulated for safety when exposed to fish and plant life in a decorative pond. It stays flexible in temperatures from -40° Fahrenheit to 175° Fahrenheit making it easy to install year round. Unlike other liner materials, it does not contain plasticizers that could make it become brittle with age and cause cracks or splits in the material; threatening aquatic life.
EPDM's flexibility provides more versatility in the pond design. Unlike preformed liners, it can be easily shaped to fit the unique contours of the pond dimensions, allowing a more creative design. It shows remarkable resistance to the harmful effects of ultraviolet radiation (UV), ozone and other environmental conditions. EPDM's high expansion and contraction characteristics enable it to conform to objects in the sub grade. Should earth movement occur, rocks and tree roots could be dislodged beneath the liner, but EPDM's high elongation will enable it to stretch over such objects. EPDM requires little or no regular maintenance once installed. However, if repair becomes necessary, it is easy to do without removing the liner from the pond with the EPDM repair patch. It installs easily and quickly. No special skills or tools are required. EPDM carries a 20 year membrane warranty.
