To support the corner of the house while the foundation was being repaired, the crew first lagged LVLs into the wall studs. View original article.
Before assembling the support for the needle beams that carried the weight of the wall, a crew member scored the concrete slab for the new footing with a concrete saw.
The crew inserted steel needle beams through openings they cut in the sheathing and supported them inside with double screw jacks that were adjusted to the necessary height.
Outside the house, the needle beams rested on solid cribbing.
The foundation walls in this corner of the building were in terrible shape and fell apart easily with an impact hammer.
After tearing the existing foundation walls back to solid concrete, the crew began excavating for the footings.
The crew dug trenches 12 inches deep and 24 inches wide for the footings, removing all the excess soil and debris in five-gallon buckets.
The new footing was reinforced with 1/2-inch rebar, which was tied to chairs pinned to the base of the footing trenches.
The rebar in the footing was wired to vertical rebar that extended up through holes in the existing sill plates (which would later be replaced), tying the footing to the concrete-block replacement foundation.
