35' Wide Pond Liner Underlay

Pond Underlayment is quick and easy to install and keeps your pond liner protected from sharp objects that can be found in the dirt beneath it. And unlike newspaper or sand, pond liner underlayment resists pond decomposition, shifting and settling.

Pond liner underlay stabilizes the ground under the liner to prevent pond liners from over-stretching, as well as extends the life of your liner. Find your 35’ underlay here, or shop the other available sizes.
