This photo is the masonry foundation repair of the front wall of a 45 year old house. It is one of many techniques that can be used for such a repair.
The masonry foundation had been suffering from horizontal cracking.
Around here a big factor contributing to this problem are expansive clay soils. Certainly soil/water pressure is the culprit, but clay soils can shrink when very dry and then, when wetted, can expand with greater force than normal.
Such force works on these walls, over time and even quickly!
When it happens, and if there has been enough movement, a structural engineer should get involved.
And one certainly got involved here!
This engineer's solution was one of many, and involved installing small, steel I-beams against a foundation wall that was pushed back into a plumb condition.
This is one of about six such posts used to gird up the structure.
They continue every six feet or so from this one toward the left.
I could detect no bulging in that wall!
Each of these posts is anchored between floor joists to become a part of the structure of the house.
And they extend below the floor slab, deeply enough to have their own secure anchor there, to be filled in with a new slab at the entry point.
It is extremely strong.
Of course, outside more work has to be done to divert water and soil pressure off of the foundation wall.
Together these two solutions provide a peace of mind that future foundation problems will not be an issue. This seller was able to provide the engineer's solution recommendations, final report and the County approval. Getting and reviewing all that paper work, my clients were very satisfied.
My recommendation: when you see something like this don't be upset! It obviously indicates a professional, and probably permanent, solution to a previous problem. And of course, any information or paper work the seller can provide is extremely useful.
