I have a newer home with a poured foundation and handmade brick exterior (per community regulations). We are now finishing the basement and have noticed water leaking in periodically through two notches in the foundation where an I-beam runs across and there are gaps. The I-beam I guess is to support a "bump out" breakfast area above. Through one of the gaps I can actually see the brick which I would guess I should not be able to see from the interior of my basement. I've had an inspection and recommendation that we put some spray foam but I'm wondering if there is more that should be done to seal this penetration? Unfortunately we also have a concrete pad and limestone patio dry laid w/polymeric sand on the exterior so at most we could dig on the exterior down below the polymeric and gravel to the concrete pad.
I am holding up construction until we have a solution so this doesn't become a large problem later behind the walls. Thank you!

Can you tell me if the outdoor elevation is higher then the beam?
Do you have gutters over this area?

Looking at the plans and just from viewpoint I believe the foundation walls go up slightly above grade. 9" ceilings in the basement. The builder re-routed the gutter for aesthetics so that the gutter route comes down and runs over a flat roof area on the kitchen breakfast area bump out and to a gutter on the other side. Last week I had it all snaked and three gutters in back of house running into a main were crushed (they were installed before final grading work). They were all replaced with heavy duty pipe (SD35?) they are 4" running into a 6" all the way through the back yard and empty into a creek. I've attached another picture. Thank you!

Well it is still leaking. A local contractor suggested that we apply mortar caulk at the seam where the plate meets the foundation wall, spray Flex Seal where the plate meets the foundation wall , spray the open voids in the cavities with a polyurehane based foam and Flex Seal on the crack in the foundation wall. Does this seem reasonable?

Also, I've called the gutter guys who are going to check and reseal all the gutter corners and run the gutter that drops over the flat roof, directly into the downspout which has the newly repaired pipe running out the back yard.

If that doesn't do it, I give up!
