walls are retaining minimal fill, and you are in a cold climate, you may have a
foundation problem, i.e. wall footing not below the frost
I just looked at a CMU wall built in a U-shape to
form a garage at the end of a house. The exterior wall varies from 5 ft
to 12 ft in height. The back wall is 12 ft high. The third side is
visible from the crawl space and has the same height as the wall on the
A concrete floor slab was placed "inside" the
walls. It looks like from the shape of the deflected wall that there may
be some minimal amount of reinforcing tied into the slab.
The 8" CMU walls are failing on all three
sides. Extensive diagonal cracks and blocks pushed out.
It does not appear that the blocks are reinforced
or have any grouted cells. The wall looks like you would expect - a
mess. The homeowner has tried parging with mortar mix and painting it to
hide it. Not a chance.
My thought is that to fix it, short of tear down
and replace, would be new concrete walls around the perimeter. Steel tie
rods could go through the end and interior wall under the garage slab to tie
the walls together. The back wall would be tied with some kind of soil
Any thoughts or similar experiences would be
