It extends the liner's lifespan and reduces the risk of damage and costly replacements. The pad also provides a thin layer of cushioning underfoot, making the pool more comfortable to walk on.

- Easy to Install: Simply place the pad on the level ground where your pool will be installed, ensuring it extends slightly beyond the pool's edge. Cut the pad to size with a utility knife for a custom fit around your pool. This pad is suitable for both soft-sided and hard-sided above-ground pools, ensuring an easier installation process for all pool types.

Normally, I would just set the pool on the cement. But this is a great product. This product was like very heavy felt, and I am sure that with a little TLC, it will last for years. It kind of stuck to the cement area I was covering, so I had to do some stretching and move the edges up and down to get some air under it as I positioned it. Very easy for one person but my wife helped me. I have a 12' round pool and I have 2"-4" of this showing around the whole pool. The posts are all sitting on the liner as well. Two very good things it provided. 1) It will keep any little grains of sand or rock from loosening and causing a hole. 2) It gave me a totally clean area to lay out the pool. I will definitely use it every year and feel much more comfortable about no holed in the bottom of the pool. Thanks for providing a great product.

This pad is perfect for a protective layer between concrete slabs and a pool liner. We used this for an Intex style pool and it should do nicely. It’s not super thick, but thick enough to offer protection from the brush finish of our slab. There are 2 seams in the pad that could show up in the pool floor once it’s settled in, but it’s too soon to tell. We have an 18’ pool and ordered the 18’ pad. The pad extends about 1’ beyond the liner on all sides. For the price point you could easily double up and spend less than some brands. Overall it will do nicely for our situation.

We replaced our liner in our 27 foot pool and we wanted a better foundation for the new liner than just the sand. Did some research and found this pad. This pad is thick, appears to be verry durable and very easy to install. We smoothed out the sand and laid this over it. We installed new liner and it worked perfectly. A definite plus to our pool liner foundation. A good value.

We were already in the process of setting up a pool. I had planed to use plastic when I found a website talking why not to use plastic. My next thought was to use weed blocker. No one wants to tear a pool down after days of prep and setting up. You want to do it right the first time. I ordered this reluctantly. When it came in I was surprised how think and strong this stuff is. I would highly recommend it. It has kept my sand from washing away. If works as advertised I will never have to worry about grass growing through it. I built a 4 x 4 frame around my pool to help hold the sand in. It stretches from one end of that to the other. I wish I had gotten it wider to stretch across the width. I have 2 feet on either side of the pool. It is easy to see how this holds the sand in place compared to what is not covered. I would recommend getting bigger than what you need.

This is essentially a thicker black felt pad. It’s easy to roll out and set up under our small above ground pool. We purchased it for our 14 foot pool, the 15 foot pad fits perfectly with a small amount of overlap. We set our pool up in brick pavers and are hoping this prevents the small tears in the bottom pool lining, which we experienced last year. So far, it seems to be working. There is a seam down the middle, which you feel when you’re in the pool, but it’s insignificant really. I don’t know if it’s reusable, because water does get under the pool. Possibly it can be rinsed and dried, once we take the pool down.

Knowing what I know now, I wouldn’t have paid what I did for this pool mat. It’s supposed to be “extra thick” (says it multiple times on the listing) but it’s definitely not. It’s basically just a big piece of felt, and felt is generally thin and isn’t very easy to work with. We put it exactly where we wanted it and it took some time to smooth it out. We put our 15 x 48 Intex pool on it and the two didn't match up, which is really frustrating because some of the pad sticks out and some doesn’t. Can’t speak to longevity because I just installed it, but being that it’s essentially felt I’m concerned with the water that gets on it and whether or not it’s going to create a mold situation under the pool. Won’t know that until we take down the pool someday. Should have just stuck with the tarp that comes with the pool.
