Hi' I have a basement with a addition that is 3/4 underground, the 50 foot poured concrete outside wall (with no rebar) is bowed along the entire span its pushed in from the top so at its deepest point it is like 6 inches deep the wall has several vertical cracks that has leaks and threw the winter since I'm in maine has opened up a little from water freezing in them, and there are two vertical cracks at the corners where the wall seems to have pushed in most. The wall looks like its falling in from the top like the leaning tower of Pisa.
the addition space has no floors over it just a flat roof (but a ton of snow falls on it every year), I was wondering what method would be best, could I straiten the wall or should I just brace it? and whats best the best way to keep water out. there's nothing outside to get in the way if I have to dig along the outside wall.
thx
What I've been thinking of doing was digging out the outside wall, pushing the wall strait with jacks , sealing wall cracks with polyurethane, installing french drain system along the outside wall, coating the wall with something like tremproof 250 and back filling with sand or crushed stone. I plan on using some of the extra dirt to create a slope away from the basement. does this sound like a good plan?
but im totally unsure about the wall itself. the vertical cracks almost make the wall a totally floating wall its not tied into the rest of the basement I have no clue on what to do to effectually tie it back in to the other walls
