Pond Liner

Building a water feature starts with choosing the proper liner for the job. Our large selection of fish safe offerings are sure to satisfy landscape contractors, water garden specialists, and pond installation experts.

All of our liners are fish and wildlife safe, UV resistant, and lay flat for easy installation.

Please be advised: Published price and availability may change due to fluctuations in liner cost and supply.

You can calculate the size of the pond liner you will need for your installation by using these formulas:

Pond Length ft + (Depth ft x 2) + 2 ft = Liner Length
Pond Width ft + (Depth ft x 2) + 2 ft = Liner Width

Example:
For a finished pond 12' long, 7' wide, and 3' deep,
the liner size you need is:
12' + (3'x 2) + 2' = 20' Long
7' + (3'x 2) + 2' = 15' Wide
This basic formula will work for all pond shapes.

The biggest contributor to pond liner failures are poor, unstable soil conditions that cause rips and tears from rocks and boulders. Shifting soil creates pockets and voids under your pond liner, forcing it to stretch under the weight of the water. Underlayment is manufactured in 5', 10', and 15' widths, and will ship to you in one or more pieces (equal to the total square footage of the pond liner in your liner/geo combo). Simply lay the pieces next to each other and install the pond liner.
