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 end.
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
The 8" CMU walls are failing on
all three sides. Extensive diagonal cracks and blocks pushed
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 anchors.
Any thoughts or similar
experiences would be greatly appreciated.
