Shoring a Sagging Floor, Images 25-28

Once the column is in place, I use the sledge and my level to fine-tune the position.

When I'm satisfied the column is plumb, I remove the nearby jacks, putting the weight of the house on top. I run two 3/8-inch-by-2-inch galvanized lag screws into the beam.

At the bottom, I install a concrete anchor to keep the base plate in place until the new slab is poured.

Work like this is not glamorous, but doing it right ensures that any renovations done upstairs will be properly supported.
