I am replacing a 11 x 26 oval pool that fell down this past winter with a 12 x 24 oval. My old liner was destroyed by gravel that came up from the sand base after 12 years. I want to reuse the base since its already level. I live in the NYC area and do not have a driveway so dumping yards of sand & wheel barreling into my yard will be difficult. So I was wondering if I could use the gorilla pad topped off with the happy feet to cushion the bottom. Or would the Gorilla pads be enough to cushion the bottom?
