Protect your pond liner from punctures, wholes and leaks with pond underlayment. Underlay is a flexible, soft fabric placed under the pond liner for protection against punctures and friction from rocks.
Underlayment is used to protect pond liner from rocks, roots, and other sharp objects that may damage the liner. The underlayment is light in weight, spreads easily, and has a non-slippery surface, making installation quick and easy.
