MaPorch 20 x 30 FT Black Waterproof Pond Liner, HDPE Black - Reinforced Polyethylene 20 Mil for Fish Koi Pond, Fountain, Waterfall, Tank, UV Resistant RPE Pool, and Outdoor Use

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.

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.

My fish pond with waterfall is rounded 8'w x 8'd x3'h + 3'h tall waterfallIt's very stiff (like a tarp cover), thin, very easy get functured if I'm not carefully lay down properly. My return time is passed, due to delay to use it. End up I have unknown leaked somewhere after the new liner installed over clean-up old liner. I have to order another rubber liner from different brands. My waisted money was gone.

Great quality and the water remains pretty clean

Arrived fast and relatively easy to instal but not ideal for a narrow, deep pond. We had to order a large size to accommodate the depth so have tons of extra material to cut and stuff. So far it's holding up well but the algae loves it so trying to get more plants to cover the sides better.

great product

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.

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.
