House is cabin construction 2×4'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.
Thanks.

A bed of gravel under 3' 6x6 sleepers or a triple stack of 2x10s should do fine. As Steve Foutz said, you're looking for surface area, and it has to be something that won't flex into a banana under load.
