Prior to the installation of laminate flooring in my ranch home, I noticed that my floor in my living room was very unlevel near the wall to my right as I enter the front door. It was not in a normal traffic path and covered by carpeting. Upon further inspection in the basement I found adjacent floor trusses as much a 3/4 inch lower than adjacent trusses. It appears that the basement wall is lower in this area of the foundation. No apparent shimming was done in this area of the wall to attempt to level.
I then took a closer look at the whole structure in the finished basement. The main support beam (three laminated 2X10’s) down the center of the house does not have any permanent columns. When it was framed a couple of intersecting walls, not load bearing by design, had 2X4’s supporting the beam to the slab.
I would like to make this right. In what order would you tackle this situation. Pour center beam footings and install Lolly columns? Then attempt to jack up the low floor trusses and shim under the sill plate? The house is approximately 35′ X 75′ long. What would be an appropriate footer construction for a couple of Lolly columns?
There is some indication of slab movement in the basement and the basement framing is solid slab to trusses – another problem.
Any advice is appreciated.
