Shoring a Sagging Floor, Images 9-16

Once the footings have been laid out I can set up the temporary supports. I spend some time making sure the cribbing is dead level.

The cribbing is firmly fastened together.

I plumb the temporary posts.

The posts are screwed to the beam above.

The posts are jacked just enough to make them tight and to loosen the existing columns.

With all the jacks in place and the old columns removed, I chip around the perimeter of the footing layouts.

I break up the concrete on the inside.

After removing the old concrete, I finish digging by hand, first with a grub hoe, then with a shovel, leaving a 2-foot-square hole 12 inches deep.
