The basement flooring here is much better than the guys crawl space i think about 12" thick of concrete. The wood beams will remember and get straight again then i can sister it up, so not so much weight in the end.
What's you solution Neil? Build a concrete wall under the beams when it is jacked up? I guess i'll do that if the floor cracks, but i don't think it will, you can see the support already bent and the concrete floor didn't crack. Sounds like lots of work too.
