Basement – Leaking crack inside basement wall

basementfoundationleak

I have had a leak down into my finished basement. When I cut away the drywall there is an obvious crack that runs to the corner of the basement window. I have sealed outside along the foundation as best as I could and it has slowed the leak, but hasn't stopped it. I would like to try to seal it from the inside before spending the big money on excavating outside. I have two questions…

  1. What is best product to use to seal this crack?
  2. Any suggestions on how to seal behind the metal support? There is only about .5" clearance between the foundation wall and the support.

The leak is coming about right where the crack goes left behind the support in the picture below.

First I would install a french drain outside. This will keep you from having further foundation damage. Then I would seal it. There are many products on the market for this. I use this product to do my brothers basement. We did two coats. It worked well. But you need to address the issue before sealing the wall. If not you will regret it in the future.
