MY 3 year old house built on a concrete slab has a new crack I found
(the 6th one) in the floor of a room where I was removing builder
(Veranda Homes LLC) installed carpet. The crack is 14 feet long and at
one end was a bad patch job that was a 1 1/2 foot hole.
I tapped on the patch area to find that it sounded hollow, then the
patch crumbled.
I found that my slab is only 2-3 inches thick in this area and not the
required 4 inches by building code.
How do I repair this hole?
Builder is uncooperative.House is only 3 years old.

Is this part of a complex of homes? Neighbors have problems? Slab
poured by sub-contractor?

Have you written to the builder? County/state construction boards and
licensing boards?

If ever there was a case for calling in the cavalry, this sounds like
one.....attorney, prosecutor, etc.
