The durable nature of EPDM means that, when properly installed and maintained, an EPDM pond liner can easily last for decades.It is true an EPDM pond liner will initially cost more than a vinyl or PVC product, but since most ponds are intended to last for years, EPDM is a good investment. EPDM is naturally resistant to the damaging effects of sunlight and weathering, tolerant of extreme temperatures, and extremely flexible.
EPDM does need protection from punctures, and that should be achieved by including an underlayment during installation. It's also necessary to maintain a pond liner by keeping an eye out for damage or leaks and repairing them as quickly as possible before the damage has a chance to spread. Give your liner that same care and attention as you give your fish and plants, and you should see excellent results. In fact, many manufacturers put their money where their mouth is and offer warranties of up to twenty years on their EPDM pond liners.
