House is cabin construction 2x4's. Dirt floor. Main support piers in the center of the house are sunk concrete, but the beams are sagging all over. Center support piers are reasonable.
I used jackposts on concrete blocks between the center support pier and outside wall. The problem was crawlspace was wet so the blocks sunk. I have remedied most of the wet problem.
So the right way to do this is to dig down 2 feet and sink some concrete, then jackposts under the sagging part of the beam. (ok should be wood pier...) I was told only screw the jackpost say 1 inch a week till its level.
Are there alternatives to sinking concrete?
It's rather cold here now and the less I have to be under the house, the better.
