Proper way to pour a basement slab?
We are trying to decide on a sub for flatwork in our ranch style home with a walk-out basement. We have several differing opinions on how the the basement slab should be poured. One states that the slab should be in direct contact with the footings. The second states that the slab should float on a bed of gravel and not directly contact the footings. Is there a standard technique or is this just individual preference? Does anyone have any experiences, either good or bad, for either technique? Thanks.
