My wife and I bought a house (built in 1985, Atlanta GA suburbs) with a fully finished basement that recently had a hot water heater leak that ruined the laminate floor. This disaster actually was helpful because after pulling up the floor, we had several days of rain which revealed some water infiltration through the block wall that we wouldn't have seen if the flooring hadn't been removed. We have been in touch with a basement waterproofing company and are working with them on that issue.
The previous owner had mentioned that she had an insurance claim due to freezing pipes that flooded the basement. She also mentioned that the insurance company's contractor had installed some steel beams behind two of the walls. None of this could be seen however, since the basement was fully finished. Now that the floor and baseboard is gone, I was curious so I cut open a stud cavity to a height of about 4 feet and had a look. There are indeed steel posts (4"square) as you can see in this picture:
The posts are 8 ft or so apart and you can see in the image that pressure treated 2x4 material has been cut and positioned as shimming between the presumably plumb post and the out of plumb concrete block wall. This post has a shim that starts out about 1-1/2" thick and tapers down to 1/8" (guess) which over the 8ft of the wall works out to about a 0.8 degree angle.
The posts are bolted into the slab and the block wall via welded L brackets. I suspect that they tie into the framing above as well but I could not see that far.
My question is whether or not this is a common method of mitigating a leaning foundation wall and if not, what can be done to correct the problem.
