How to fix a large vertical gap
Hi, I am at a loss as to what I should do, and am hoping that the wonderful minds here at GW can help me out. I have an outdoor entrance to a basement door, steps leading down approximately 8 feet. The issue is that a huge gap (approx 1" wide at bottom, 1/2" wide at top) has developed between the foundation and the concrete wall of the stairwell, and during a rainstorm the water pours out from the gap. Any ideas how to fill this gap? I live in Canada, so freezing and thawing is an issue.
Thanks in advance for your suggestions.
