USA Pond Products' - Pond Liner - 4' Wide x 6' Long (1.2m x 1.8m) in 20-mil Black (.50mm) PVC - Fish and Plant Friendly for Koi Ponds, Streams, Water Gardens and Fountains

This liner is really thick and tough. I used it to build a small in ground water feature. My soil is really sandy so I just used that for padding and shaping the bottom. I did, however, put down a weed blocker for the tree roots before filling the space back in with sifted soil. Then I just filled with pond rocks and planted the borders. Held water just fine and continues to do well. Birds love bathing in it.

This pond liner was heavy duty and seemed very durable. Unfortunately, I couldn't figure out a was to conceal it in my 8" deep round fountain +

The media could not be loaded.  Wanted a small pond in our yard to complete our zen atmosphere. This liner works perfectly and actually fit the hole we dug almost exactly. Only had to trim off the corners. It molded to the shape of the pond so much better than the liner we bought at Lowes some years back for another pond. Cannot comment on durability since we've only had this for a week. We did get algae a few days after creating the pond, so this does not resist algae sticking to liner...but it is in full sun, which we fixed by adding shade. I recommend this liner...it is inexpensive and so much nicer to work with than the pricier one we bought at Lowe's.

It was exactly what i expected and was hoping for!I actually used this to repair my pool liner since COVID has everything for pools so incredibly expensive. I was left with enough spare product for future patches and this worked fantastic with vinyl cement!Yes it is black patches on a blue liner but I honestly do not mind because my pool is fixed!Super easy to work with, it actually made me want to purchase more for a pond or water feature in my back yard.

I use this as a floor protector under a project area. I've spilled all sorts of detergents and dripped paint on this thing. It's done a great job of protecting my carpet, and has held up to the foot traffic on top of it. The legs of the table are pushed down into the carpet through it, and it's holding up just fine.That being said, I have no clue how it would hold up for it's intended use outdoors.

Was the size I was looking for beat the big box stores prices for comparable size and value recommend highly don't know about durability only had it two months

Didn't use this for fish, but it worked great for its purpose! We used it to line our guinea pig's wood cage, and it works perfectly. The guineas were able to chew a couple of tiny holes into it (our fault), but after they each took a nibble and realized it wasn't delicious, they stopped. And the holes were easy to hide with some black electrical tape. The liner is very thick and sturdy. It doesn't tear and is easy to manipulate.

I am using several of these liners in a waterfall feature for my Japanese garden. They are tough but flexible for covering the contours of the waterfall. I really like that they are made in the USA, too!

The liner is thick enough and durable . I just wish I would of ordered a bigger size . But shipped quick and was what I expected .
