There was a segment on Hometime (or one of those programs) a few years
back about having concrete pumped in below a slab (or part of a slab) to
correct such problems. ISTR they showed an attached garage that was
'sinking' away from the house, which was cured with this process. They
can apparently do differential pumping, to tilt it back into place.
