Dumb question: why not drill out a couple inches of earth under the foundation on the side that isn't sagging to let it sag that way? Use a high pressure jet or something similar? I mean, those high pressure water jets they use to cut metal are cool. The issue is getting it to settle evenly? So you dig down on the sides and then use something: a long drill, a water jet, to open up small 1 or two inch channels. Are there high power lasers that can do this? With the stresses, the building will crush out the small open space and... settle?
