Our pool is on our way and we too were looking for the footprint so we could get started leveling. Our entire 2 acre property is on a slope and leveling is very hard. We have decided to put this on our very large back porch. However our porch is also at a slant (about 2 inches) for water runoff. We were going to frame it with 2x4s and use sand to level. Has anyone else done this on concrete? We know the concrete is thick enough to withstand the weight of the pool we just are not sure about how to level the pad without permanent damage.
