Aquascape Heavy-duty Pond Underlayment - 10' x 12'
AQ-42139
Heavy-Duty Pond Underlayment, 10' x 12'
The Aquascape Heavy-Duty Pond Underlayment 10' x 12' (3 m x 3.7 m) covers medium-to-large backyard pond builds where a 10' x 10' piece falls slightly short of the pond's longer dimension. The extra 2 feet in length eliminates the need for a seamed joint in the most critical part of the installation.

How to Use
Prepare the excavation and lay underlayment over the cleared substrate. Overlap adjacent pieces by 6" (15 cm) if multiple sections are needed. Install EPDM liner over the underlayment and fill the pond to seat both layers. Trim after conformation to the pond profile.
Ideal for medium backyard pond builds with a longer axis approaching 12 feet, where covering the floor and lower walls in a single piece without seaming reduces installation time and potential weak points.
