Re: Black stuff (mold?) on basement wall.

What's that L shaped corner in the inside? Is that pre-fabricated concrete corner or steel? In any case, the bond between the mid L corner and concrete is not good enough and you have a leak.

Agreed with previous assessment, this can only be fixed from outside. Nothing you'll do from inside will help long term.

Uh, this just looks like a regular old poured concrete foundation wall... no brick fascia or stud space.

There are a number of masonry sealants that can be used on the outside of that wall to prevent water infiltration from driven rain. I'd start there.

First, I'd mix up a solution of bleach and water in a garden sprayer and kill that mold on the inside.

Not sure what the corner is. I assume it's just a smooth concrete edge. I should have looked at it closer from the outside.
