Sagging Floor

317 Views 3 Replies 4 Participants Last post by  chandler48
I have a sagging floor. I am going to support and raise it with a beam and jack posts which will rest on the basement floor. I am concerned if the weight on the jack posts will crack/break the concrete floor. The present jack posts in the basement go through the concrete floor and I assume are sitting on footings beneath. The floor is in good condition now. Will there be a possibility of the weight breaking the floor? Should the posts be on some kind of support pads?

Or cut an 18" square out of the concrete and dig down to 8" below he floor top and fill that with concrete.
