I use this as a dog pool, it was large enough a piece that I doubled it up. It is polyethylene, so it's slippery but easy to clean. Lay it out in the driveway, not the grass. It took a couple days of watering to bring the grass back.
This product is very heavy when ordered in large size. Be sure to have assistance to manage. Weight works in its favour when installed - excellent quality.
This liner gets hot if left in the sun and it will burn you so get a good pair of leather gloves and do not leave it on your lawn very long it will burn your grass.
This line is great. I was a little leary buying without seeing it, but it was thick and quality was great. I have no worries about it laying for forever and my pond looks so good!.
