Features
- [Durable & Leakproof]: The KOI pond liner is with unique five-layer structure design. The middle is reinforced HDPE with net structure PE and leafproof coating on both sides. Its more durable and leakproof than most pond liners in the current market.
- [Easier to Work With]: Thanks to its unique structure, the fish pond liner is softer and more flexible. It's easier to fold and cut to any sizes, so as to fit for nearly any shape ponds outdoor. We understand how hard it is to work with when the pond liner is too stiff.
- [Excellent Performances]: Because of its five-layer structure, the pond liner is with relatively high puncture & scratch resistance. Suitable for high & low temperature environments outdoors. We have tested repeatedly that the pond liner can be used for over five years.
- [Widely Used Applications]: Our reinforced PE pond liner was originally mainly used for large-scale aquaculture and waterproofing projects. Now we could use the it for duck & fish/KOI ponds, man-made waterfalls & fountain, raised planter bed or pool ect. Your ponds need a lasting liner.
- [Warm Tips]: Please level ground and place underlayment before laying the pond liner, such as sand, old carpet and any others sheet of fabrics. Avoid hard and sharp objects to pierce pond liner. Please freely reach out to us if you have any questions, we will work it out until your satisfaction.

I waited a year before sending a review. Here goes: I got the 25x25 size for a 1300 gallon, 4ft deep outdoor pond with rocks and gravel and plants. I could not afford fleece underlayment at the time so i just used some plastic shower curtains from the dollar store to give some kind of padding. It has held up superbly. During construction I accidentally dropped a 40 lb land scraped log onto it - it hit the sloped side of the pond hard and scraped down the side. But it's been a year and it still does not leak. All parts above water are covered with rocks or such to protect it from UV damage. underwater parts are less protected but still show no sign of wear. I'm very pleased with this product and would buy it again should i decide to do another pond project. Please note though - this type of pond liner appears to be more difficult to repair so if you plan to frequently walk in your pond or do other wear and tear of this nature then you may want a different kind. But for me, it's been ideal and perfect. Thickness - good. quality - good. leakage - none. ease of installation - let it sit in the hot sun for an hour or two to malleable, then good. it has endured my pond plant roots.

I purchased this pond liner after installing the cheaper HDPE pond liner and it started leaking immediately after adding 1500 gallons of water so I had to take the HDPE out and ended up folding it up and using it as an underlayment for this liner which actually worked out pretty good. but this liner is much better and won't leak if you have large fish or monster fish like catfish and gars. Because large fish will bust the HDPE 20mil liner. The installation went smooth everything was good so far so good with this liner and my fish haven't busted it yet and it's been almost 3 weeks, so I do believe this liner will hold up and last for a while. I can't vouch for the three layer rpe liners but I can say that this one is thick and seems much stronger and I believe it will hold up to my large catfish and my alligator gars.

Great price on this huge pond liner. Installing it on a warm sunny day definatly helps to make it more pliable. This kind of liner is fairly thin but super stong and puncture resistant. Our dogs climb all over it and the deer walk on it regularly with no punctures.

So far so good. I would have given a five stars but I've only had it installed in my pond for one season. No leaks! Yay! Next year I will try to remember to come back here and update to five stars if there are no leaks. I do suggest you have someone help you as I did, especially if your pond is large. Mine's only 10x7 but I was glad for the help laying it down

The media could not be loaded. So far so instalación when very good, material looks strong and water level stays high for 2 days already. Now we will see for how long it stays like this.

Update 2: the Company never delivered on their offer to issue a refund. Anyways, this product is basically a black tarp and proved unsuitable in using as a pond liner. Update: After my review, customer service reached out quickly to offer a replacement or refund. There is a possibility that my liner was a resale and that a prior purchaser caused damage to the liner. Since I have already rebuilt the pond with a different liner, I have opted for the refund because I do not wish to rebuild the pond for a third time. I am grateful for an understanding and accomodating customer service for this product. I ordered the liner to use in a fish pond. Upon opening, I discovered a small circular hole in the liner. I assumed this was a manufacturing defect and was able to work around the hole because I bought sufficient liner to use on the pond, waterfall, and bog area. The plan was to stack rock against the sides of the pond. I used a thick pond pad to protect the liner from anything underneath. I carefully placed all rocks and then filled with water. The pond never held water. When I started removing the rocks to look for the issue I saw numerous holes in the liner created by placing rocks against it. The liner was useless. I removed all rocks and replaced the liner with a 45mil pond liner which works perfectly. Save your time and money and do not use this liner for your pond.

Very happy with this purchase. The first delivery was left outside of the gate, which is near a public sidewalk, which was unfortunately stolen. But a replacement was promptly sent and left inside the gate this time. The liner was very durable considering it wasn’t as thick and heavy as the rubber liners I’m used to working with. Don’t let the lighter weight material fool you. I was very surprised at how puncture proof and flexible it was. It was a lot easier to work with and just as durable as the rubber liners I used in the past. I used it to line my above ground 1500 gallon Koi pond. So far, no leaks and the size was just as described. Would highly recommend.
