A floating slab is thickened anywhere a load bearing wall will be and all around the perimiter,so your saying your slab is not done this way??

It has no footing. This is a slab.of concrete..sitting on grade..monolithic slab has a foot 12"to 18"inches below grade..

Very common, and perfectly legal here in Florida for many years. We seldon seem to have any trouble with them as sand is one of the absolute best foundational bases you can find..... as long as you keep it from eroding away.

That's what the gravel is for... to direct the water run-off.

BTW, that drawing shows a little less than 8" at the edge.

There is no gravel there is no footing along outside where walls are.(perimeter)

Say it was not built to code? That was 33 years ago. Water under the bridge. (Kind of like Obama... a mistake of supreme magnitude, but we're stuck now.)

As bondo said, get it re-supported, and keep it from doing anything more.
