I got a new liner for my pond. The old one is a rubber liner and the new one i got was a 20 mil like a woven type liner. Alot thinner and a little stiffer. Has any one used this kind before. Its almost like plastic feeling but alot more plyable. I got it from just liners. I called them today and they said it will work just fine. Just a different type of material. Just looking for some input on this kind of liner.
