By the end of this post, you’ll know more about what goes into your pond construction project.
Which Pond Liner is Best?
EPDM rubber liners are the best choice for ponds due to their flexibility, durability, and fish-safe properties. They easily conform to intricate designs, withstand temperatures from -40°F to 175°F and last 20+ years. A 45 mil EPDM liner is non-toxic, UV resistant, and easy to install, making it ideal for fish-friendly ponds.

What is an EPDM Pond Liner?
EPDM pond liner is made from M-class synthetic rubber. The M refers to its classification in ASTM standard D-1418; the M class includes rubbers having a saturated chain of the polymethylene type.
In other words, this freshwater pond liner keeps water in, won’t poison your pond or yard with toxins, and doesn’t damage easily.

How Long Do Pond Liners Last?
Pond liners typically last 20–40 years, depending on the material, installation, and maintenance. Durable materials like EPDM rubber and reinforced polyethylene (RPE) can last for decades. Proper installation, regular maintenance, and minimizing exposure to UV radiation, temperature changes, and sharp objects help extend their lifespan.
How Do You Repair Pond Liner?
Small holes can be patched with primer, liner adhesive, and a liner patch or piece of cover tape. Larger holes usually require you to get a new liner.
You can repair a pond liner leak by following these 5 steps:
- Empty your pond so the water level is 1 foot below the hole
- Clean 4 inches of liner around the hole
- Prime the hole
- Cut the patch so it’s round (corners fray and peel up)
- Apply patch
How Do You Clean Pond Liner?
To clean a pond liner, drain the pond water and temporarily house fish and plants. Remove debris with a net or vacuum, gently scrub the liner with a soft brush, and rinse using a low-pressure hose. Inspect for damage, patch tears, and refill the pond with treated water before reintroducing fish and plants.

How to Measure Pond Liner
Measure the longest length and width of your pond, along with how deep the deepest part is.
Then, use these equations:
- Max length + (2x depth) + 2 x 0.15 meters = total liner length
- Maximum width + (2x depth) + 2 x 0.15 meters = total liner width.
Then multiply the two numbers to get how many meters of pond liner you need.
You’ll want to do two times the depth because the liner has to go down one side and back up the other. The .15 meters is for overlap because you always want some extra liner.
