45' Wide Pond Liner Underlay

Pond Underlayment keeps your pond liner protected from damage by creating a barrier between your liner and sharp objects found in soil. It also stabilizes the ground under the liner to keep EPDM and other pond liners from over-stretching.

Pond liner underlayment is quick and easy to install and resists pond decomposition, shifting and settling. Extend the life of your pond liner by purchasing this 45’ wide pond liner underlay, or shop the other sizes that are available.
