Flexiliner Pond Liner reviews
40yr pondliner 18x10
The old butyl liner was heavy and had to be glued together causing the inevitable leaks. This liner was one piece, light and easy to manipulate, took two of us just an hour to line the 15m x 5m pond. It has been full of water for 3 weeks now and no leakage! Great product!
