Sagging Floors and Cracking Walls


The existing structural members consisted of a combination of deteriorated 4” X 6” wood beams and columns and temporary shoring devices (non-conforming to building code) all of which were deemed to have footings that had insufficient load bearing capacities. These findings were found to be factors leading to unsafe conditions, sagging floors and cracking walls.


Replaced the inadequate beams, columns and footings. The installation procedure involved removing the wood beams and columns and replacing them with double Laminated Veneer Lumber (LVL) beams and steel columns that were set in steel reinforced concrete footings. Temporary shoring was installed to support the structure while the old structural members were being replaced. The shoring was also used to incrementally jack up the floor joists, at the beam location, to a level position. Once the level position was achieved, the new beams and columns were set in place as illustrated in the following photos. Any electrical, HVAC and gas lines attached to the existing structural members being replaced were removed and reinstalled once the new columns and beams were permanently set in place.
