  • Pool Pad
This covered the area it needed and then some. Its a little thinner that i was expecting. But still good quality

  • Good quality and nice and thick pad for under pool
I am not able to use it yet. I am looking forward to using it next summer. It seems a good quality, nice and thick. I think it’ll work perfect

  • excellent quality heavy weight
This is an excellent pool liner pad. It is about the equivalent to an 8lb needle punched geo-textile filter fabric, which is what you want for durability, & also so water can pass through.
