I would (hammer) drill a hole at the current bottom of the crack, no need to dig to bottom. "Controlled cut" on the outside, concrete caulking..wasabi wrote: ↑Interesting.
We have a ~5" crack in our poured concrete foundation running vertically from a basement window. I've dug a foot down under the crack and noticed that it does not extend below grade. I've done water tests and can only assume water (very little shows up under the bottom plate in the basement) is cascading down the brick facade and into the crack.
I've spoken to my usual general contractor who has been in touch with his "waterproofing guy", a company well known and very well reviewed in Durham Region.
According to him, in his experience, epoxy injections have been failing as cracks get larger over time. He's suggesting he dig down to our footings, I believe he said he would make a controlled cut, then epoxy that cut.
Total cost $800
As expensive as this sounds, I'm willing to do it if its the RIGHT thing to do. On the other hand, I'm not thrilled about throwing money away for no reason and if I can do this myself, I just may give this a shot..
