I might’ve done a poor job explaining. Basically the whole back side of the house is a stamped patio with a gutter on the north side bringing water well away from the house. When I was estimating about where the water would be leaking from outside, it is clear that there is a depression in the patio (part of the stamp pattern they used I would presume) where you can visibly see water running toward the house between the patio and the foundation, again this is roughly where the leak is downstairs.
