Footings for Jack Posts in Basement?
I'm planning on putting in 2 jack posts in my basement to slowly raise up a few joists to level in preparation to install a new support beam, but I was unsure about what sort of footing I should have for them. It's a concrete floor on a two story house, so I was thinking a couple of 4x4s on the floor would work.
And then when it comes time to install new permanent columns for the beam, I was unsure about footings for those, too. My thought was to cut a hole for each column, dig down 2 feet and use a little rebar and concrete to build up a footing. But I guess I wasn't sure if that was deep enough to dig. Any ideas about how much of a footing I should plan on?
