Firestone PondGard Pond EPDM Liners are Fish Safe with a 20 Year Limited Manufacturers Warranty. This Top Grade Tear and Puncture Resistant EPDM liner is perfect any size pond, adding a stream or for lining your waterfall.

To figure your pond liner size use our Pond Planning Calculator or take your measurements:

1. Maximum width
2. Maximum length
3. Maximum depth

Now take your maximum depth and multiply this number by 2. Take this figure and add 2 for your overhang (this is counted as 1' for each side multiplied by 2). Now take your total and add to your maximum width and add the same number to your maximum length. You will most likely need to round up to match one on the pre-cut liner sizes.
