Ethylene propylene diene monomer are highly flexible and incredibly durable liners, especially resistant to punctures. These can last up to 30 years, making it one of the longest lasting investments you can choose when it comes to a pond liner. These can be custom manufactured to fit any specific pond shape, and are resistant to the kind of damage usually associated with pond upkeep.
EPDM doesn't expand or contract, even in extreme temperatures. This makes it much more likely to maintain its grip, despite periods of freezing and heating. EPDM is additionally fairly good at resisting punctures and tears.
