I have a 3x4' concrete stoop just under the side garage door. Since
1992 it has been sinking. About 1997 I dug under it, used a car jack,
and put rocks underneath. It has been sinking and now is 6" below
were it was. I'd have to remove some landscaping to repeat what I did
in 1997. Is there an easier way? I can't be sure if the land is
sinking or the builder buried refuge that is now decaying.


Maybe a hydraulic spreader. I'm sure you could rent one, or find
something like this on ebay:

These can generate ton of force, which should help.
