sinking pilings

[armadillo9]

I bought a 10-yr-old cedar 2-story built on a lakefront slope. The downhill side is about 6 ft above the ground. The house is supported on a series of 2x12s attached to wooden pilings. I've checked them with a laser level and they vary as much as 5 inches from the highest to the lowest. I don't know how deep the pilings are in the ground, nor if there is any substantial footing under them. Obviously, the house is a mess in terms of drywall & window & door problems. Iwould like to unbolt the 2x12s, jack them up level, shim under them, and re-bolt them to the joists. I'm not flush with money. I don't know if the pilings will continue to sink and undo the repair. Will I be sorry?

It sounds like the piles were not driven to hard pan. Someone knew there was suspect soils which is why piles were driven to start with.

Leveling the house would probably be temporary unfortunately.

Request from the city or township any building plans and then it will be necessary to hire a geo-engineer to perform soil borings to get the proper depth and repair options.
