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.
The main trouble spot sits next to the water heater where some old oil tank lines were. Can I safely cut those out with an angle grinder and try to patch that up? There’s a giant concrete hump that encases them where the water leaks over too.
Our exterior is naturally moist. We’ve got a sump pump, French drain, gutters discharges all well away from the house. Short of digging up and putting in new footer tiles (which I definitely can’t afford now), I’m at a loss.
Any suggestions would be helpful. Waterproof paint? Block filler?

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.
I have an older 1970s house that has a similar problem more so since climate change has been increasing the amount of water dropped in a storm.
The actual best thing is it get out the shovel and start digging. Installing a French drain and plumbing my gutter spouts and moving that out flow 15 feet away from the house fixed all my water issues.
And while I was putting back the soil I ran new landscaping fabric to reduce weeds as well as to grade the 4 feet of surface next to the house.
