See attached detail. What you describe is the underbuilding arrangement in the new workshop/office going up on my place at the present time. There's 10M rebar throughout the foundation, kerb and slab that's tied together to a grid of 10M rebar at 24" in the slab.
This detail was devised mainly to comply with the seismic codes here. The foundation, kerb and slab are designed to act like a large box frame so any subsidence due to seismic movement might see the whole structure tilt but the risk of building collapse due to part of it giving way should be reduced.
As it happens, there's mesh in the floor as well but it's purpose is to act principally as a shrinkage crack inhibitor. The slab is 70' x 26' and crack free. )</font>
Very nice. We have no seismic coeds or activity here, but that's almost exactly what I build, but maybe even a tad more overkill since your slab actually sits on a ledge on the kerb (I'd call it a curb). My slab "floats" within the block walls unless customer wants it on a ledge. The only thing I would change is a substitute of fibre-concrete for the wire mats.
Thanks for sharing that!
