Pond liner life is increased with the addition of Pond Underlayment. Liners are made more puncture resistant thanks to this barrier between the liner and sharp objects in the soil. Pond liner underlayment also helps stabilize the ground beneath the liner, preventing EPDM and other pond liners from over-stretching.
Underlay is easy to install and resists shifting, settling and decomposition, unlike newspaper or sand. Find your 30’ wide pond liner underlay here, or browse the other available sizes.
