I have a hairline crack radiating from a corner of a window in the basement. This crack weeps water during very heavy rains. I have sealed the crack with urethane injection (Sika Crack Injection Kit), however there is an area of the crack that is covered by a stud of a wall running perpendicular to the basement wall. It seems that that part of the crack is still allowing a small amount of water to enter the basement.
Blue is the window, brown is the stud, black is the crack, green is the ground level outside the basement. The red outline is where the current crack seal was done. The top part of the crack is dry, and it looks like I have water coming in from just the part of the crack behind the stud.
The area of the crack is unfinished (the wall is there just to partition a workshop from the laundry/storage area), and I could remove the stud temporarily to gain access to the crack.
On the outside of the basement, there is a 2 feet wide strip without grass, so I have no problem digging there to reach the crack from the outside. The area that I did not seal is pretty shallow, so I'm wondering if it might be better to seal the crack from the outside (with the same urethane injection material)?
