Protect your pond liner from damage with Pond Underlayment. Pond liners are at risk of being punctured by sharp objects in the soil, and pond liner underlayment creates a barrier to keep them safe. They also stabilize the ground below to keep the pond liners from over-stretching.
Unlike newspaper or sand, pond liner underlay resists pond settling, shifting and decomposition. It’s also quick and easy to install. Find the 50’ wide underlay to keep your pond protected here, or shop our other sizes.
