40' Wide Pond Liner Underlay

Want to extend the life of your pond liner and keep it protected? You’ll need to invest in Pond Underlayment. Unlike other materials like newspaper or sand, pond liner underlayment resists pond settling, shifting and decomposition. It also stabilizes the ground below to prevent the pond liner from over-stretching.

Pond liner underlay makes your pond liner puncture resistant by protecting it from hazardous and sharp objects found in soil. Find your 40’ wide underlay here, or browse the other available sizes to find the right option for your needs
