Folks, I hope this is the correct forum for this question. My client’s house (approximately 40 years old) is set on a concrete slab (typical 4-5 ” thick). One of the rear corners of the slab (and ultimately the house) has settled about 3″. The settling starts approximately 10′ from the corner. The cause of the settling (sinking) was due to excessive water draining into that corner from gutter leaders over several decades. The gutter issue has been fixed/rerouted, but the sunken slab remains. Has anyone heard of slab jacking and if so, would this be an option in this situation? Any help or references would be appreciated.

Never heard of slab jacking but I've heard of grout pumping. Might be just what the doctor ordered.

Yeah, grout pumping (better known as "mud jacking") is what you want. Often done by a small specialty operator -- you may have to ask around, but there's bound to be someone in your area that does this.
You should note that this operation doesn't generally result in a totally stable situation -- the operator will generally overjack slightly (maybe 1/2" in this case) to allow for settling likely to occur in the first 12-18 months afterwards. So any fancy plastering, etc, of the area should be delayed.
Also note that the operator will need to drill holes in the floor, maybe 4-6 feet apart. (Filled afterwards with patching cement.)
Not perfect, but it's a heck of a lot better than nothing.
