Pond Liner Underlay

Pond Liner Underlay is recommended for all pond liners, including Firestone PondGard EPDM Pond Liners. Pond Liner Underlay 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.

Key Features

• 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
