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....
Jackhammer the floor out. Lay down weeping tile that drains into a receiving basin with a sump pump. Rent a backhoe to dig around the exterior of the foundation, and seal the trouble area with rubberized sealer.
There are finer points for each process, but that’s the gist of it.
