It had cracked diagonally across one corner about half of a 7x7 square.  When I stripped all the siding and sheeting I wanted to resquare the building.  I looked at the cost in time and dollars to jack up the building, bust the concrete, and re-pour.I got a quote of $300 to mud jack it and decided to give it a try.  They drilled a couple of holes with a gas powered jackhammer and fired up the grout pump, but the slab didn't want to lift.  After a little investigation we found the sidewalk that goes around that corner of the building had also settled and had the slab wedged in.  They drilled a few more holes in the sidewalk, quick jacked it up and then went inside set a couple of levels on the floor and in minutes had the floor slightly above level to allow for a little settling.The filled the drill holes with grout and troweled them off and were on their way.  That was three years ago and the floor is just like they left it.My neighbor had his entire driveway jacked.  It was about 20x45.  You have to look close to notice where they drilled the holes.  He was also very happy with the work he had done.The grout is a fortified cement product with fine aggregate. Its consistency is thin compared to concrete to ease the pumping.</blockquote>
