I live in las vegas and we have dessert landscaping and to make it worse a lot of Caliche in the ground. My entire backyard has Mojave gold 3/8 minus rocks. When you walk you don't feel anything sharp and it feels soft. Since the pool will only be used 3-5 month and stored the rest of the year it's not worth to remove all the rocks just to end up digging into caliche which is worse. I'm thinking of using some type of padding to be on the safe side on top of the rocks and putting the intex ground liner on top.
Searching here I've found different options like gorilla pad, carpet, carpet tiles and regular padding at home depot. Any suggestions and will I be ok?
