20' Wide Pond Liner Underlay

Pond Underlayment is easy to install and doesn’t take much time. It protects your pond liner from damage by providing a barrier between sharp objects found in the ground and your liner. Pond liner underlay also stabilizes the ground beneath the liner to keep pond liners from over-stretching and resists pond settling, shifting and decomposition.

Consider a pond liner underlayment to extend the life of your pond liner. Choose from various sizes to ensure the perfect fit for your pond liner.
