Perimeter wall blocking

Post by redRocket » Wed Sep 07, 2022 10:16 am

Perimeter wall is sagging, in the middle (length wise) of a 16ft Solitaire mobile home. I’m a mobile home novice but I’ve inspected the floor joist and rim joists, they both appear in good shape (no rot). I have not inspected the wall studs. The kitchen counters drop an inch towards their back (sidewall of the MH). I suspect the sagging issue is just age and weight and maybe some I-beam deflection. My question has to do with the engineering of a solution. The floor joists are 16 inches center to center and the concrete blocks are also 16 inches wide. I’ve been advised to lift by rim joist which is only 1.5 inches wide. So, would it be best to support the load from the center of the blocking or at the sides? Another way to say this would be should the shims be under the center of the block pier or on the ends of the block pier? On the ends could be directly under two floor joists and the rim joist while centered would be only under one floor joist. I’m thinking of placing a 4x4 beam across the perimeter span between the outriggers at the rim joist and have the shims directly below the 4x4 located where the floor meets the floor rim. Thanks
