The problem,a row of garage lockups.There are about 8 garages in a line,the rear wall is quite high about 15'.This wall has moved away from all the seperating walls on each garage,the crack runs from top to bottom on each wall.
Cant put a retaining wall on other side because there is a small drainage ditch (which over the years hasn't helped)

I'm thinking of some kind of metal bolted to the inside walls then through the back wall.Something like what you see on old buildings outside walls.

Just wondering if any firm makes this stuff,or otherwise i would have to have it custom made.
