I've got a wedge/corner crack on one corner of my foundation. I'll try to post a picture of it as soon as I can, but here's a sample image of what I'm talking about:
However, my crack is more complex. There are actually two pieces. The upper piece looks like the one in the picture above, and the lower piece looks like a mirror image, such that the two broken pieces of the corner are wedged against one another at their tips.
This makes repair problematic, since the two pieces are wedged against one another so well that I can't pull either free to put any kind of repair compound on the back side of the cracked pieces. If I simply fill over the crack, I'm worried that it won't be strong enough to hold the pieces to the foundation, and it will just crack again.
How would you suggest that I should proceed? I'm thinking I have these two general options:
- Try to inject some repair compound as deep into the cracks as I can, hoping that I'll get it deep enough to bond the pieces to the foundation.
- Do my best to remove the pieces so that I can apply repair compound directly to the back surface, even if that means doing more damage to the pieces themselves.
