Koi Pond Liners » Butyl Pond Liners » 4.5 Meter Width With Underlay & Felt

Polyester Liner Underlay is recommended for all pond liners, a 250gsm underlay made of non woven needle punched polyester, offering high puncture resistance and good flexability.

• 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
