Am thinking to dig out one side to about 6" depth and fill with couple inches of sand..the other side will need to be filled more, my neighbor says just fill with sand, but I think I should fill with 4 or 5 inches of crushed limestone then inch or two of sand on top....is this one of those 6 of one half dozen of the other type deals?
should I put a footing around perimeter? if so how big? or would that be overkill. and would a footing say 1' deep by 1' wide be a problem with frost? what about just pouring concrete 6" thick at perimeter, would that be ok?
With the drainage issues here, think I need a moisture barrier....What should I use?
also thinking 3/8 rebar - spaced about 18" sound right?
any advise appreciated.
