We have pretty nice ground underneath with small pebbles and compact dirt after removing all the sod. There are random little roots here and there but the grass is gone. We gave up the idea of sand, gorilla pad and tarp (which was going to help with leveling out the pebbles) and we are going with foam board.
Question 1: Do we still have to have a tarp between the foam and the pool?
We have a double liner (we bought an overlap liner that we installed inside of the pool, making a double wall already) and we're not sure if we have the foam, why we would also need a tarp. At this point, anything we don't need to buy is helpful as pools always seem to cost more than we expect!!
Question 2: If we do need a tarp, does it have to be heavy duty? We bought landscaping fabric to go around the perimiter of the pool where we're going to put river rock, so it seems a bit overkill to have a tarp AND landscape fabric.
