You might want to investigate slab jacking. It is a process by which cementitious grout is injected under the slab to fill voids and support the concrete.
We have a 3 year old exposed aggregrate driveway that is developing cracks. When I tap on the area that is cracking, I get a hollow sound unlike the rest of the driveway which doesn't sound hollow when I tap on it. I'm guessing the underlying base has shrunk away from the concrete. Any suggestions? At this point, the cracks aren't real noticeable, but they seem to be getting larger.
