Ok so they call it floating slab foundation?
Since I was a kid I had watched them pour the outer perimeter of a house foundation ,, then later pour the inside and not attach it to the slab.
I thought this was crap then and I still think it is crap now.
Bugs can get between the slab and outer wall .. and it does not seem strong at all.
The way I was taught to pour any type of concrete was like this. With lot's of rebar all the way through the footing and the slab.
Dad and his friend poured a 30x? garage and did it like this with rebar and welded wire both in the 6" slab.
Here is a picture.. and they did not cut any expansion joints and in 25 years it did not crack apart.
