TotalPond 7 x 10 ft. PVC Pond Liner, For Ponds up to 200 Gallons, 14.5 mil, Flexible and Easy to Install, Durable and Strong Reinforced Mesh Weave, UV and Tear Resistant, Multi-Purpose Use, Black

The best liner for the price. Tried many in Amazon and they all sucked. They where so stiff they cracked but this one is flexible and easy to shape to my pond.

Pond liner seems extremely thick. Easy to work with. I believe it will last for years. If I had to purchase again I wouldn't hesitate to purchase this again.

This is a nice pond liner. I believe its 16.5mil thick. Abd it has like nylon strands going through it to reinforce it more. It really feels strong. Its shipped well packaged and it was easy to unfold. It formed to my pond very nice. It easy to work with. I am very happy with this And belive it will hold up for many years. My ducks and geese love it. I posted a few pictures, But my pond is not close to completed. But it has been full of water for over a week now and its great. Wish the water fall and all the plants and rocks were in place. My pond is 14ft × 9ft and 2ft deep after getting the liner in placeand working everything to fit nice theres plebty of liner to do the job. I will pist another picture after to follow up.

This is a great value for its price for a simple DIY project, but we warned that weeds are a great danger to it. It's relatively durable, but even something as simple as nutgrass will penetrate the liner in time, leaving a bunch of holes that will make the pond or waterfall fountain leak more and more over time. So I highly recommended something thick and durable to protect it from underneath if you're laying it over dirt or anywhere weeds can grow. A fabric underlayment won't be enough. If its a bigger project its better to spend more money on an EDPM liner that's much more durable so you don't have to worry about weeds puncturing it.

It came nice and folded, with zero blemishes or scratches or any cuts. This is expected, and receiving something fated to leak from the get go would be unacceptable to many. It may seem quite pricey, but for the price you pay now, you get much more out of it in the long run, with much less worry for the liner to tear or just have things go wrong. It is easy to trim off the excess liner as well, and it worked really well for my pond build. It does the job, and the quality is very good as well, which gives me hope that I won't need to bother with it for quite some time.

I continue to be impressed with these pond liners. We have three koi ponds and have used these liners for all of them. We have natural rocks lining the inside of the ponds. Some are granite and have sharp edges. Never had a problem with holes, tears, or leaks. I’ve bought others in the past that will puncture immediately, even the thicker plastic ones. That is a huge pain when you think you’ve finished your project and you realize you have a leak and you have to start again, never mind trying to get a refund on something like that. These are definitely worth the money. They are also easier than most to manipulate when laying in the ground. 11/10

Good liner for the price. Very pliable

I used this to line a 4'x4'x1.5' deep square wooden pond built of 2x4 and OSB. I was trying to get the wrinkles out so I filled a few inches of water and started tugging vertically on the walls to smooth it. There were five leaks near the upper edges of the walls. Based on the location of the leaks midway up each side and no leaks on the bottom I knew it was from tugging on the liner. I found the leaks by first feeling for moisture then using a flashlight to visually spot water slowly dripping when pulling the liner slightly away from the vertical side of the pond. I marked around the holes with masking tape so I knew where they were, then I drained the pond and removed the liner. Based on some advice from searching Google, I patched the holes using Oatley X-15 from plumbing aisle of big home improvement store. Cut a 2" patch from scrap liner. Work outside or with ventilation for the next part because the x-15 fumes are strong at first. On the outside (smooth) side of the liner daub the X-15 lightly with the included brush, then place the smooth side of the patch there and slide around a little to distrubute the x-15 on the patch and the liner. Remove the patch and place face up for 3-4 minutes allowing liner and patch to become tacky. Place the patch back on, then put on a flat surface with a large flat book and about 10 pounds of extra weight on top for four hours to compress the patch, then remove the book and allow to cure for 12 hours. Practice one patch on scrap liner first since you need to judge the right amount of X-15 - it works by dissolving the liner and too much will cause the liner or patch to bubble apart into two black PVC plies and a white inner nylon mesh. Once patched, my pond stayed full for a week with no leaks or moisture, but I decided to replace the liner anyway with a new one since they're not very expensive. This time I DIDN'T TUG on the liner, only gently pulling and smoothing it into place, and there were no leaks whatsoever.
