Pond Liner Underlayment

Starting at: $6.25

Liner Underlay is recommended for all pond liners, especially Firestone PondGard EPDM liners. 
  • Makes all pond liners more puncture resistant
  • Protects pond liners from sharp objects in the soil
  • Stabilizes ground under the liner to keep EPDM and other pond liners from "over-stretching"
  • Quick and easy to install.
  • Resists "settling" unlike newspaper or sand.

Liner Underlay is available in 5' and 15' widths x any length desired up to 300' long.
