Concrete Wall Crack Repair?
I have a crack in basement wall and sometimes after a heavy downpour I have water come in. Took drywall and carpet off to see where, it looks like from a crack, starting from corner of window all the way down to floor, it seems the builder or previous owner had tried to seal it from inside.

I'm going to dig outside to expose the crack also. Can you give me advise in how to fix it properly, please. Or does this has to be given to the pro? Also better slope I need away from house and a window well I want to put in ...any advise would be nice.
I'm thinking of chiseling along the groove about 1/4" deep V groove for some silicone? But better let the expert decide.
