Pond Liner 7m x 7m 40 Year Guarantee Plus Underlay


Really pleased with it at first but I used it for a duck pond and the ducks have picked away the black liner from the white adhesive so a bit worried it will start to leak now. The edges were not well stuck, a little wrinkled, which allowed the ducks to be able to pick at it so think my 40 year guarantee is out the window.

Underlay is needed to protect the liner from the sharp stones this brand is thick and easy to use
