Has anyone had any experience having their foundation jacked up?

10. have had a couple issues w my 115 yo greystone.

when we bought it, a bay on the side of the house had slipped off it's footing. we dug out around it, and poured a yard and a half of concrete around the base, almost up to the soil line. that stabilized it.
we had to sister several of the floor joists, and repair openings of the floor, too.
there was a lot out of kilter in that area, and later when we replaced windows it was a pita.
still have issues w mice getting in from the small cracks in that section of the house.

later we dropped the floor in the basement. that meant replacing all the posts, and we replaced a section of the main beam to open up the space.
we had a good rec for the contractor. but there was settling that put some doors a little out of kilter, and cracked some plaster. not sure someone else would have done any better.
usually in an old house it is best just to accept the settling, patch what you can. trying to jack it back up to level would have caused more cracking.
everything has stayed stable since then.

i saw the coolest video a while back of a process where they pump a foam under concrete slabs to level out settled concrete. i have a small slab on grade under my back porch that i fantasize about having that done.
