   Sorry Gene,

   But this is a structural problem that requires on site advice from an engineer. The load on your slab, the perimeter shape of your slab, the structural strenght of your slab, the substrate etc are all items that must be factored into a solution.

   Off the top of my head, assuming that the settling has stopped, you may have to raise the house and cap the slab with pea stone concrete or gypcrete and then reset the house down on it.

   Residential slabs aren't known for their strenght, therefore I don't think that it could take the stress of pressure grouting with any type of a load on it.

   I second Gabe's advice. A competent, fully licensed professional engineer qualified in foundation design will be able to tell you how to fix your problem properly and safely the *first* time. His/her fee is money well spent, IMO.

   Foundation problems can be dangerous, especially in the hands of those who don't know what they are doing. Jacks that slip out from under the house are lethal. If that doesn't kill you, the collapsing building will finish you off.

   I have a house built on a slab foundation where one corner has settled about 3 inches. Does anyone have experience using compaction grouting to correct settlement?
