I have a frame built out of 2x6 that is level across the top, but 5"deep on one end and slopes down to about 11 inches on the opposite (long) end on the ground surface itself. I was thinking of using all masonry sand for backfill. which would make the underneath of the sand pad un-level but the top would be level. after reading some posts, everyone talks about only 2" of sand for a base. I need some ideas on what to do in this case. I read one that said use unwashed gravel to level unevenness and then top it off with sand, water and tamp several times. This is my first install and I don't want to have to redo it. The frame work is 2 feet or better all the way around the pool dimensions. Please help

I suggest leveling with 1" minus limestone compacted in rises of approximately 2" to achieve proper compaction. A vibratory plate compactor will be your best friend for this project and can be rented for around $40 or less per day. After you have leveled the area put down your 2" cushion layer of masonry sand. You definitely don't want an uneven sand base as sand shifts with pressure on it.
