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?
Unfortunately replacing your drain tiles, and new waterproofing is the best option. Patching, or waterproofing from the inside allows hydraulic pressure to dislodge the coatings. Whereas on the outside the pressure pushes the waterproofing against footers, or walls. Somewhere I have seen a inside perimeter drain tile. Mounts up against the floor wall corner. Have no idea if it would work. I sympathize. Wish you the best of luck.
I’ve seen that drain system and I think that might be the least expensive way to deal with it. I’ve heard mixed reviews but generally it seems to work. Our layout makes it tough to run it along the perimeter to the sump pump but it’s still more accessible than digging the exterior or drain tiles.
I appreciate the help.
