We carry a full line of flexible 45 mil EPDM pond liner and installation products to create the perfect pond or water feature. From large commercial ponds to small water gardens you'll find the perfect installation and repair products here.
SIZING A POND LINERFirst, you will need three pond dimensions- length, width and max depth. These measurements should be all be made in feet. You’ll then add the length to two times the depth plus 2. You use two times the depth because the liner needs to go down on both sides. The extra two feet is for overhang. This gives you one extra foot on each side.
-
The formula will look like this:
- Pond Length + (2 x Max Depth) +2 = Length of Liner
- Pond Width + (2 x Max Depth) + 2 = Width of Liner
- For example:
- Longest Length = 10’
- Widest Width = 6’
- Deepest Depth = 3’
- 10’ + (2 x 3’) + 2 = 18’
- 6’ + (2 x 3’) + 2 = 14’
So, the liner needed for this pond is 18’ X 14’. More often you’ll need to round up or down since liners are cut in 5 ft. increments. The closest liner size, commonly available for the above dimensions, would be a 20’ x 15’ liner.
