Hi all, really hope someone can suggest something for this problem. Had a few people over but no answers.

At the far left of my basement, where the basement wall meets the ceiling I am getting some water leakage. It is a poured concrete basement. What I can see, is this is also the area of my house where there is concrete patio outside. Right in the crack where the wall meets the ceiling, I can see some of the cement has fallen away a bit, and I can see wood (i'm guessing that is what is underneath the patio). I'm guessing this can't be fixed from the inside? I have also cocked the patio itself, so at this point, I'm thinking that the water is somehow travelling underneath the patio, and then comes inside.
Thanks for ahead of time for any tips or suggestions.
