Polyethylene Pond Liners

Polyethylene is stiffer than other materials making installation more difficult in backyard water gardens. When purchasing a backyard pond liner for smaller backyard ponds, we recommend EPDM Pond Liners. Large ponds require a pond liner that is safe for fish and plant life, inexpensive, easy to install, and durable enough to last twenty years or more, making Polyethylene pond liners the ideal pond liner material for such applications.

Polyethylene Pond Liners are extremely UV stable and are able to withstand temperatures from 180°F to -70°F. Polyethylene Pond Liners are backed by a twenty-year warranty. The 20 mil medium-density polyethylene liner costs 25¢/ Sq. Ft. and the 30 mil pond liner costs 35¢/Sq. Ft. These prices are FOB Shawnee, OK and do not include shipping.

Please allow an extra 3 days for your liner to be seamed. The maximum sizes for fabricated one piece backyard pond liners are:

  • 20 mil: 40,000 Sq. Ft.
  • 30 mil: 26,680 Sq. Ft.

We offer full installation services if your backyard pond liner exceeds these limits.
