When I first unboxed this product, I was a little disappointed at how thin it appeared. However, after using it two seasons now, I see how durable it really is. This will not provide any cushion under your pool, but it will do an excellent job at protecting your liner. After the first season, we had to take down our pool to level the ground in an area that had sunk. I was amazed that here were no tears in the padding at all. Our ground is full of gravel and small stones, and it is impossible to remove them all. We even had a few larger stones that could be felt from inside the pool, and this padding I'm positive prevented damage to the liner. Highly recommend.
