Pond Liner, 20 Mil 7 x 10 Feet Pond Liners for Outdoor Ponds, Black HDPE Fish Pond Liner for Koi Ponds, Streams Fountains and Garden Waterfall

First things first, the material is thin but strong, it isn't rubber so it won't mold immediately and there will be creases as it gets laid in, however, once inside, we found that adding river pebbles of varying size and weight, helped hold the material down. Then we started filing it with water, which helps the material mold itself and further sink into the soil.This is southern Florida, so the soil here is rocky and has natural lime stone, the lime stone we couldn't dig out we covered with moist soil and mud, we did this before we laid the material in. With the weight of pebbles and water, it began to mold almost immediately.Also, we did this around 7pm, sun setting afternoon, by mid-day, the heat from the sun will further aid the material to molding around the opening.The remaining material I'd recommend one not to cut, we placed decorative concrete stones around it and over the excess, used soil from the hole to fill in around and over material and then mulched it to further hold it down. What you see in photo is this.Again, it isn't soft rubber but it's pretty good for a small pond which is about 7 ft long and 5.5 wide. At its deepest it's about 2.5 ft, at its most shallow about 10 inches.I'd recommend the material, the size is more than adequate for the laguna we had in mind. We should have put another layer on top of it, but it's strong as is, we've walked around inside it and it feels sturdy at 20 mil.Comes folded up tightly. Didn't notice any tears or holes in fabric. It's been holding water for hours without issue. So far, very good. Price point couldn't be beat and the reviews are pretty good. Will update with more photos when it's finished.👍Update photos as pond/laguna takes shape. Liner is still holding up without issue.Liner is folded beneath stones, as you can see the stones are heavy (over 40 pounds each) and some are stacked. We did this to make sure the material stays in place, doesn't shift towards submerged center. Also, has some security for wildlife currently in pond (fish and turtles).Inside liner is holding about 100 pounds of river pebbles. Hand chosen so as not to tear or poke liner. I recommend using smooth stones and rocks.For the curious: the submerged plant is Egyptian papyrus, other plants are Water Hyacinth (native to Florida) and wild grass orchids 🙂

Nice and thick, sturdy too. It won't mold to your hole, though, so plan to fold it and disguise with rocks if you want to hide it.

This was a difficult purchase for me because I had no prior knowledge on this type of liner. I'm so glad I finally purchased. It's not the easiest material to shape, but my pond has a lot of dimension and this worked out fairly well considering. No doubt in my mind that it will be better than the liner I replaced it with. Durable material that warms easily in the sun and becomes flexible. I also took a heat gun to it in certain spots and it made it easier to work with. I should have bought this a long time ago, but the ratings on this type of material made me shy away from it. If you're looking for a durable pond liner or waterproofing, I would definitely recommend this liner without hesitation.

I bought a home that had an old unused pond that I needed to get back into operation. The home was 22 years old and I am sure the Michelin liner was original. However, past owners had butchered the liner when adding a new pond skimmer and it leaked so much it was abandoned. I bought this liner as it is certainly much cheaper than the Michelin liners and I laid it on top of the old Michelin liner. This liner is thick, it is strong, but it is also fairly stiff. It was sunny and hot when I installed it as other reviews said that helped keep it more pliable. A light breeze was blowing when I laid it out and as the breeze would blow the edges over, I would have to go straighten it out again. But when I would pull the creases out it would still be stiff enough that it would leave a crease in the tarp. (See pictures) I had to be so very careful placing the rocks back on the tarp as I was paranoid that it will damage the tarp. I have filled it with water, and after 2 weeks there is no sign of leaks so far.I don't think the product description is false or deceiving, but I do believe this tarp is not for every application. After working with this liner and the Michelin liner, there is a huge difference in the material. The Michelin is basically the same material as a tire innertube. Hence the maker...Michelin. It is strong and pliable. It will last 20+ years. I am sure I will be replacing this liner again in about 5 years do to the bending I needed to do for my application. If you are doing a simple shape in your application, this tarp will do the job and probably last 10 years. In hindsight I wished I would have just forked out the $400aprox for a rubber liner so as to not do this job again in my lifetime. I hope this review helps in your decision.

This is an excellent liner! I made a 10 x 15 pond 18 inches deep. It does get very hot while exposed to the sun. We used astro turf from Lowe's to cover the liner out of the hole. I would buy again. Don't forget underlayment, we used linoleum.

So I installed it summer 2024 and it was fine. We have had a normal summer as far as heat, nothing extreme. I walked out to look at my pond today and it is splitting everywhere it was not completely covered. So it is junk and a total waste of money. I might as well flushed that money down a toilet. Now I will have to completely redo this pond in the spring again....It seemed the right weight but now it will leak and have holes...If I could give -1 stars I would. It was a lot of work putting this together now it has to be completely torn down and done over. My liner before this lasted several years.

I used this product to line custom planters we had built alongside our patio. This is a very high-quality, durable pond liner. Would definitely purchase again.
