Underlay for Pond Liners

Polyfelt Heavy Duty Pond Liner Underlay Pond Liner Underlay provides exceptional protection from the ground of your pond or lake liner. The underlay is manufactured from a non-woven geotextile that offers exceptional puncture resistance from sharp stones and invasive debris. Pond Liner underlay is recommended for use with all our liners as it reduces stretching of the liner during settlement and protects the pond liner for its life expectancy.
