Beckett Corporation Flexible Pre-Cut PVC Liner - Ideal for Small Ponds, Koi Ponds, Water Gardens, and Fountains - 12 Foot x 17 Foot, Black

Thick, reinforced and easy to conform to irregular shapes and angles, tougher, and heavier than I expected. I am coming up on a year of use, in a 900 gallon pond with no problems. It has handled temperatures over 100 degrees last summer down to -10 below zero at over a mile high in Colorado. Water is VERY expensive here, so a leaker would have been a huge problem. I have accidentally dropped a granite slab and a metal fence post into the pond, both times expecting a leak, but none yet. I walk on this liner when maintaining/cleaning the pond and at 225 lbs. I still haven't had a hole or tear. Excellent product, and price!

I bought two of these for Aquaponic grow beds. I have had them for a few months and have not had any issues (rips, holes, stretching.....) The grow beds that they line are made out of concrete blocks. They are being used in St. Croix USVI so they get a lot of direct sun (or did). I did built an overhead structure to cover the beds with shade cloth, that seems to keep the plastic from getting to hot. I will be buying these again when I expand to new grow beds.

If you want a durable pond liner get epdm, this split and leaked after a couple of years

The thickness of the liner is perfect. It hold water well and forms to shapes beautifully. The price is also fantastic!! Look no further than this product for your project.

I laid this out in the sun for a day to soften it and pull out the wrinkles, then cut a cardboard section the same size as the pond bottom. Measure your walls and bottom and trim the liner to size, then place the cardboard bottom form in the middle of the liner, and fold the sides to the center like wrapping a present. Worked great, much easier to handle, slid right into the space, then just unfolded the walls one at a time, tidied up and back folded my corners, set temporary stones to hold in place while it filled with water. The cardboard for was great to stand on while I worked the edges. Nice mid weight liner, will have to see how long she lasts.

We were very pleased with this liner for our lawn pond! Great quality!

So far so good with this liner. I liked the fact that its not super thick, but definitely strong enough. This is just the right thickness, and my pond looks good so far.

Very thin Liner would not recommend this to anyone that does want to have a leak pond. had to repair three holes right out of the box.

Not happy with it , paid lots,had it installed, there is leaking within few days.
