Jessie, screw jacks were exactly what I had in mind when I referred to "shores", up the thread (screw jacks may be used as a type of shoring).
The beauty is just that they can be "tuned" incrementally, which is usually done to cut the most annoying resonances from footfalls, as opposed to the simple function of raising sagging floors.
The potential for tuning increases if one can more or less "Earth" the floor above into a slab or the Earth.
Generally, these shore jacks are used along with wooden or steel beams that run perpendicular to the ceiling/floor joists above.
I have also seen shore jacks used to tune ceilings, although this is a bit more involved).
Got a soggy floor?
Screw it!
