  • Great quality
Color: Black Size: 16.5 x 26.5 FT
This pond liner has been great! It was the size we ordered and we haven't had a single leak. Highly recommend if you are looking for a well priced pond liner.

  • So far its been great
Color: Black Size: 20 x 30 FT
After a year of use, this liner has proven its durability by consistently holding water, even enduring freezing temperatures and occasional foot traffic. Initially inexperienced, I underestimated the importance of proper landscaping, leading to some issues with heavy clay soil washing in. However, after a thorough cleaning and reinstallation, I'm impressed by its resilience. I couldn't get all the muck out by hand to remove the liner and what was left was extremelyheavy, so what I did was tie a corner to a tow line on my truck and I pulled the whole thing out. Honestly, I expected to destroy this liner in the process, but it survived completely unscathed. I'm currently in process of enhancing its appearance with gravel and rocks for a more natural look. While I've been cautious with heavier rocks and jagged edges, it's necessary for the desired look. Contrary to some negative reviews, my experience has been positive, though it's worth noting it may not be suitable for a natural swimming pool. I'll provide updates if anything changes. ... show more

  • Do not buy this item, if you do you will have serious regrets like me.
Color: Black Size: 20 x 30 FT
Okay I cheaped out, instead of buying the EPDM .45 liner (like my last pond had with no leaks for over 10 years, I moved so it’s still probably fine) I bought this cheap garbage that FAILED! In under a year. Yes it’s lighter then EPDM, yes easier to position, cut, cheaper etc.. However if you don’t want to completely redo your pond don’t buy this and just get the more expensive liner. This weekend I am shoveling and moving hundreds or pounds of rocks and stones, moving plants and frogs all so I can put them all back again with a liner the lasts. A million bitter curses on the makers of this cheap horrible garbage may they find themselves parched in the desert and come to the one oasis for a thousand miles only to find it was their liner that sprung a leak and there is no more water. ... show more

  • Excellent liner!!
Color: Black Size: 16.5 x 26.5 FT
Spend days trying to decide on a liner so happy i decided on this one!! The price was great for the size and it is Super durable and easy to work with i originally wanted a thicker mil but read they were to hard to shape. I exspect this one to last the material is just the right thickness and the way its woven makes it durable. my turtles and goldfish are super happy to finally have thier outdoor pond😁😁 ... show more

  • I would buy this product again. As of now.
Color: Black Size: 16.5 x 26.5 FT
7-24-22..I will add more pics when finished to give an update on this product. When opening package, the liner material felt very thick and tarp like which worried me for flexibility. But seemed solid and more thick then I was expecting. Before install I placed it out flat in the sun on a 100 degree day for about an hour. Then placed it over my pond. It naturally has creeses as expected considering my shape and depth areas. But I was able to lay it in nicely and it has held up so far. If it fails or starts to wear at edges or wear points I will report back. Though I feel I am going to be happy with this product. ... show more

  • Best for price
Color: Black Size: 16.5 x 26.5 FT
The media could not be loaded. So far so good. I think I made the right decision on the type of liner. This was relatively easy to work with and no leaks now that I’m finished. Time will tell. I hope it holds up. I was able to double line it since my pond is only about 10x4.

Great quality and the water remains pretty clean

  • Poor Quality for Price
Color: Black Size: 16.5 x 26.5 FT
It gets the job done with minimal issues so far, but the fibers are of poor quality despite the thickness of material. I haven't yet had an issue, but I am almost resigned to be waiting for this to fail prematurely at this point. I hope to be pleasantly surprised with this lasting and will update if it does better than expected. ... show more
