14 x 14 FT Pond Liner, 20 Mil Fish Pond HDPE Liner, Pond Liners for Outdoor Ponds, Koi Ponds, Garden Fountain, Waterfall

I use this for my 1000 gallon koi pond and it has held up amazing going on 2 years now it’s not very heavy the water retention is good it’s true to size and it’s a amazing price for high quality as your getting for your money

Excellent quality durability flexibility. We had an emergency with our pond. The old liner had a hole in it and was draining the pond. I found this one ordered it and it arrived the same day. Now my fishies have a new castle and they are so stoked. I highly recommend this supplier and this pond liner.

Quick delivery. Easy to work with.

Great value for the cost! The material they use is a little stiffer than I would have liked. It is a little difficult to mold it to ground without it getting bumpy from air pockets. Takes a lot of work to get how you want it. But the item seems very durable. I even accidentally poked my drift wood into it and it didnt even poke a hole or scratch it. Definitely worth the money.

This fit the the space properly, cuts easy, how’s the water well. Should last a long time nice thickness.

This was a good investment. My son created a koi pond in our yard using this liner. It is really thick and did the trick beautifully. It moulded to the shape he dug out so it created the look he wanted.

I bought this HDPE “pond liner” because the reviews seemed decent and the price looked great. Unfortunately, it turned out to be a big mistake. Mine started leaking almost immediately. I don’t know the exact cause, but the material tears very easily, and once there’s a leak, it’s almost impossible to find—let alone fix. HDPE can’t be glued, which makes repairs extremely difficult. You need special equipment and heat-sealing skills, and you definitely can’t do that underwater. With proper pond liners, you can at least use underwater patch kits. Not here. Looking back, I realize that trying to save money on the liner was the worst place to cut costs. Building a pond is a major investment of time, labor, and planning. If the liner fails, the whole project fails. This product simply isn’t flexible or elastic, has very low tensile strength, and cracks or punctures far too easily. In my experience, it behaves more like a basic tarp—fine for covering something, but not for holding water long-term. Maybe this material was originally intended for something else and is just being marketed as a pond liner, but for a real fish pond, I cannot recommend it. Save yourself the frustration and spend a bit more for a proper, high-quality liner with a real warranty. Stay away from this one.

Good pick
