1950s house with block foundation. I’ve patched these areas with hydraulic cement. That didn’t work so I stripped and cleaned the areas thoroughly then repatched. It improved but still getting lots of leaking where the foundation and floor meet or just above....
No expert, but maybe look into foundation patch, for where I am, it’s a rubberized sheet that would glue to the outside around the affected area. Once back filled, the pressure from the dirt is more than enough to keep it in place. I have done that kind of repair before, and it worked for years after till the place was sold. As repairs go, it’s inexpensive. You just need a shovel time and the patch. Just do your homework as to it being a viable solution for a block foundation as mine was poured, but I don’t see why it wouldn’t work. As was said before, trying to fix it from the inside is an uphill battle.
