At Dreamscapes Watergardens, Inc. we've been renovating and fixing ponds and waterfalls for almost 20 years and have seen everything used for pond liners (even repurposed roofing liner, which is not designed to be submerged and has toxic chemicals on it). After everything we've seen, we always choose to use 45 mil EDPM pond liner made by Aquascape, Inc for every job we install by Dreamscapes Watergardens, Inc.
45 mil EDPM Pond Liner and Underlayment
- Exceptional resistance to solar UV, ozone and oxidation - won't crack like concrete
- Rugged and flexible - Cover with rocks and gravel to expand the life expectancy indefinitely
We recommend using an equal size layer of underlayment under your liner to prevent friction between the liner and any debris or rocks within the dirt. Friction could cause tears or holes in the liner to form which leads to leaks.
How to Install a Pond Liner:

As a amateur pond installer, we recommend you begin your process ALWAYS by excavating your water feature first before you purchase your pond liner so that you don't come up short. Often we find people at our retail store buying extra liner because they dug deeper than they planned and only realized it once they tried to install the pond liner. At this point, trying to seam together multiple pieces of liner can be hard for a new-comer, as any small discrepancy will cause a HUGE problem. We also always recommend to measure TWICE and cutting once.
We sell our liner in specific WIDTHS, as they come in 5', 10', 15', 20' and 25' widths. So if your measurement came to 18'x28' like on the picture to the left, we would recommend a 20' wide liner, cut 29' long for 6" of overlap on each side. You may want to consider overlap, because your rocks will settle a little bit the first year which tugs the liner down.
Below are the most common DIY pond sizes with their respective liner sizes.
8'x11' pond= 12'x15'
11'x16' pond= 15'x20'
21'26' pond= 25'x30'
Once you know what size pond liner you need, buy it and the same size underlayment. To install it, start with the underlayment, ensuring that you have complete coverage for all exposed areas. Secondly, stretch the liner according to length and width of pond and lay in the pond hole, making sure to smooth out as many wrinkles as possible and to minimize folds and creases. Double check that you have appropriate overlap around the perimeter of the pond so that as you lay your rock, the liner doesn't sink.
