Pond Liner Underlayment is recommended for all pond liners, especially Firestone PondGard EPDM liners. Pond Liner Underlayment is available in 5' and 15' widths, but you can use it to accommodate any size pond by simply overlapping multiple pieces with no seaming required.

  • 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

This item is sold by the linear foot, so simply enter the length required into the quantity field. Example: to order a 5' wide x 15' long piece, enter a quantity of 15 under "5' Wide Underlayment" below.
