Low-cost pond liner can be cut to fit your individual pond design! UV resistant, puncture and tear resistant, these high-density PVC pond liners are 20 mils thick and flexible. They are also safe for fish. The 7 ft x 10 ft size is perfect for waterfall construction. Three sizes for ponds up to 1,500 gallons. All have a 15-year limited manufacturer's warranty.
We recommend using a Pond Underlayment underneath the liner to protect liner from rock or root damage. If your liner does get damaged, a convenient item to have on hand is a liner repair kit which works on materials such as PVC.
How to Calculate Liner Size: To find the dimensions of the liner you need, take the desired length and width of your pond and add two times the desired maximum depth. You'll need some overlap on the pond banks to secure the liner in place, so add an additional 1-1/2 to 2 feet to these figures. For example: For a finished pond that measures 10 ft long x 15 ft wide x 1-1/2 ft deep, you'll need a 15' x 20' liner.
