yeezoo 40X40FT Reinforced Large PE Pond Liner, KOI Pond Liners for Outdoor Ponds, Enhanced 5-Layer Structure Pond Liner for Fish, Duck, Garden Raised Bed and Waterscape Pond(0.82oz/sq ft Thickness)

Good thick hefty pond liner that forms well if placed in sun and you dint rush your fill. We have a cat that thinks he is a fish and has syringes for claws. No issue. No issues with random deer getting into pond either no leaks no seepage. Our last liner from a big name supply store had constant seepage. We can know control the growth of out surround plants very good value and in this instance the sizing was surprisingly over generous. . At 40+x40+ boxed it is heavy but once laying out for install quite manageable

durable and easy to install

Pretty decent but definitely not a one man job. It isn’t easy to set up and manipulate yourself. And it gets hot

Easy to work with

Run! Far away! Worst liner ever! If you so much as step on this liner and it will tear. Even look at it wrong and it will present you with new holes and leaks. Absolute garbage product! Cost me much more in lost water, time, and energy than any potentially “savings”. Worst product ever. Constantly had yo repair until deciding just to replace all together in under 6 months. DO NOT BUY THIS POND LINER UNLESS YKU WANT TO LOSE ALL YOUR WATER!

If you're building a pond I highly recommend this liner tried to cut it myself. It is not easy. Was able to but it was complicated to do so. Also, don't forget your pond liners before your pond tarp That was my mistake

Heavy duty

I found the material extremely hard to work with. Most of the liners that I have used in the past are more of a rubber texture and capable of somewhat molding or stretching to the non-conforming shapes and challenges of a pond. This was like a giant tarp or slip-and-slide. I'm almost to the point of scratching the whole thing and ordering something else.
