Am building a house with a small basement; roughly 12’x22′. Basement and foundation walls are concrete block (dry stack method). I plan to form up and pour the footers; then form up and pour the basement slab; then build the block walls outside the slab (on the footers) installing expansion material between slab and block walls.
My question is do I have anything to gain by permanently tying the slab to the footers with rebar stubs in the footers -or- would I be better off just letting the slab float on the footers.
Slab is well below frost line and footers are all the way down to the rock layer (shale).

normal is to build walls firsst, then do the slab.
regardless, be sure you have well compacted soil under the slab
