Adroiteet 10 x 15 FT Pond Liner, 20 Mil HDPE Pond Liners for Outdoor Ponds

I had 2 previous and my ducks ripped right through. However after reading this liner and what it had and its durability. I prayed FINALLLY what I need. It’s a little tough by yourself it get it in because it is “stiff” for solid made. I made it work and it works like a dream!!!! They have even made an entrance “slide” in the one area. Highly recommend

Finally! A good pond liner from a seller that didn't lie about how thick it was! I measured this as soon as it arrived because other sellers on the big online flea market, and even here on Amazon as well, have been selling pond liners for half the thickness as was advertised... But this one actually measured 25mil (0.025in)! This 20*20ft liner was purchased in September of 2026, and was actually advertised as 20 mil, so I consider it a great deal.

I used this to fix 2 small holes in my pond liner I suspect from a mole or vole. It worked well. Followed instructions, cleaned area, cut and stuck on. My little frog pond holds water again. Saved me buying a new liner.

Just received it. It's more of a plastic than a rubber. It's holding water and doing its job for now. I have no idea they durability or how long it will last though.

This is a thick material well made and is water resistance no leak very sturdy and great priced easy to work with and work well for a homemade pond for my aunt was very happy with her gift

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.

Excellent liner that is very sturdy and waterproof. I have used it on top of an old shed roof to protect from rain, etc. The 20 Mil thickness is sturdier than thinner Mils that are too easy to tear and don't feel like they will last as long. For a few dollars more, this liner is wealth worth the investment.

Good amount for the price

Not that flexible. You can bend it but it's not bendable like EPDM. Definitely needs to be out in the sun for a while before you can install it and as soon as you add cold water you can forget about trying to mold it.
