How to Use
Clear the excavation of sharp material. Lay the underlayment over the prepared substrate. Overlap adjoining sections by 6" (15 cm) minimum. Place EPDM liner and fill to seat both layers. Trim excess after the liner conforms to the pond shape.
The non-woven fibers conform smoothly to contoured excavation profiles without bunching. For projects where both pond dimensions fall near 10 feet, this pre-cut piece eliminates measuring and cutting, and reduces the liner-edge waste that a longer rectangular piece would produce. Pair with a Firestone PondGard EPDM liner for a complete pond floor assembly.
Ideal for medium pond builds, koi pond floor coverage without seaming, and waterfall stream sections up to 10 feet in length or width.
