EPDM is flexible, inexpensive, and extremely waterproof, making it a popular liner for backyard ponds, lakes, and man-made streams. EPDM is durable and resistant to degradation resulting from exposure to sunlight and ozone, and when properly installed, it can be expected to last for decades.
EPDM liners are easy to repair and simple install. The flexibility of EPDM allows it to conform to even the most irregular pond shapes, including bends, shelves, corners and curves. EPDM pond liners are non-toxic and won't leach chemicals into the water, making it safe for both fish and plants. EPDM pond liners should always be installed with a protective geotextile underlayment.
