Polyethylene is stiffer than other materials which makes installation more difficult in backyard water gardens. 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 plus. Polyethylene is the ideal pond liner material for these applications.
Polyethylene Pond Liners are extremely UV stable and able to withstand temperatures from 180°F to -70°F. Polythylene Pond Liners are backed by a twenty-year warranty.
The 20 mil medium-density polyethylene pond liner costs 30¢/ sq ft and the 30 mil pond liner costs 36¢/sq ft. These prices are FOB Shawnee, OK and do not include shipping.
The maximum sizes for fabricated one piece pond liners are:
- 20 mil: 40,000 square feet
- 30 mil: 26,680 square feet
** We offer full installation services if your liner exceeds these limits **
