Pulled up basement carpet and noticed water soaked subfloor (insulated floor).
Removed drywall and found a tiny “void” that water is leaking through and into basement. Wondering the best way to go about fixing this. My thought is to chisel out around the void to make it bigger/deeper, then fill with hyd cement. There is no loose material around the void, so maybe I should just pack the cement into it without enlarging.
Any ideas what might have caused this? Wondering if it was an air pocket from when foundation was poured, but I don’t see how that could extend the entire width of the wall.
I don’t see any cracks in the poured wall.
The basement wall is about 5 feet below grade.
Grading outside could be improved for sure, but the sump pit is dry even after thaw/heavy rain.
