So i've decided that I need to jack up the floor...


Okay. I don't think the cribbing will help me here, since I have probably less than 18" between the beam and the dirt. Would it be easier to use a premade pier block?

I might buy 2 or 3 of those 20T jacks in case I need to re-position something.

I'm assuming a steel plate between the jacking head and the beam is the best option because a piece of lumber will probably split, crack and deteriorate rather quickly, as it doesn't have the compressive strength needed for that application?

I probably won't even need a post between the beam and the jack if i can easily elevate the jack 6" off the dirt.


As for the amount of space, I dont think it will be so bad. 4x10 beams (i think) so in between the beams, i have a good 24" of crawl. That's a lot for me just as long as nothing comes down on me. (not likely considering the amount of the floor i need to move.)

You are only lifting a short distance--and if something fails--the house will drop back only an inch or so---

Se if you can find a short section of rail road tie or other heavy timber---I don't trust concrete blocks---they can crack to easily---but once again--the worst that could happen is the house settles back an inch or so---

Thanks Mike. I bet my dad has a chunk of railroad tie around somewhere.
