  • A very tough liner!
Size: 10-Foot by 13-Foot
The media could not be loaded. This is a very thick & durable liner & if you don't have it in the sun, heated up before you start working with it, you're gonna hate trying to line your pond with it. But if you do it right & let the sunlight heat it up, it's easy to lay down. You're not going to get all the creases out tho. It's impossible with rubber material this thick. But I wasn't worried about that, becuz I put boulder sized rocks around my pond to hold it down & it obscures the creases. As for durability...this liner is tough! We were walking all over it, sliding & rolling boulders on it & not one puncture or cut. I honestly believe I could've just used this liner & not worried about sharp rocks poking thru it, but I had already bought thick pvc tarps for underlayment, just to be on the safe side. ... show more

  • Still holding water
Size: 10-Foot by 13-Foot
I built a goldfish pond about 2 years ago. Liner is still working. You need warm weather to install it. It's a little stiff.

  • Depends on your application
Size: 15 ft x 20 ft
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. ... show more

  • Thick
Size: 7-Foot by 10-Foot
This served as a liner for a small water feature. It held the water very well all summer with zero issues. The real test will be how it withstood the winter months. It is thick and fairly easy to work with. I will update my review in the Spring but, so far this is a great product for the price.

  • Very stiff and hard to form into place
Size: 7-Foot by 10-Foot
Horrible product, wasted 4 hours installing then filled with water and overnight 3 cracks formed where the liner was folded during shipment. Don't waste your time with this stuff, they should not be selling it.

  • Hard to use
Size: 7-Foot by 10-Foot
I wanted a smallish frog pond and thought I could get by with this really inexpensive liner. It is very stiff and doesn’t want to bend. It was really hard to fold at corners. By the time I was finished, it had a leak about 5. Inches from the top.I’m using it for something else or I would request a refund. It will work nicely for my living roof project. ... show more
