Garage wall leak

[MarlynOC]

Water comes in garage from rear wall at bottom where wall and floor meet. Outside wall is 4 ft underground where it meets floor. Wall is painted with Dryloc and part of floor is painted as well out about 3 inches. In heavy rain the wall/floor corner leaks and puddles on floor. Any ideas how to stop leak?

I've never seen a leak like that fixed from the inside. You need to make sure that the roof gutters are installed and draining properly, the grading around the building is correct, that the exterior drain system is installed and working correctly and that the outside of the wall is properly sealed. Pictures of what's going on outside would be helpful in soliciting a more specific response.

As mentioned above an outside picture would help us a lot. I wouldn’t waste your time on interior fixes as well. Door from the outside and do it right and you will never deal with that again. Concrete block is extremely porous. And IMO the only way to properly address the issue is from the outside.

I recently fix the foundation on my own house from the outside and my basement is clean, dry and odor free now. Yours would be easier because it is only 4 feet down as opposed to me having to dig 9 feet down for my basement.

Hilltopmasonry - nice job on the repair! I hope you also installed perimeter drain tile and a sump crock while at it or daylit the tile if opportunity existed.

On poured in place concrete foundation walls I have had very good success with epoxy injection from the outside. However this technique I don't think is applicable to CMU foundations (aka "cinder block").

I think downspout rearranging, grading, and excavation are your options. Excavation the most sure path to success but also likely more costly.

Congratulations Hilltop!
That is an extreme, but totally correct, way to fix this type of problem.

And it is an example of how a new build should be done.


To the OP:
Gutters, downspouts, and outside grading are the first steps to avoiding Hilltop's solution.

Winter is getting here real soon, may have to wit until spring to get to this. Guess the shop vac will get a work out.
Gutter down pipe extends out about 3 ft and goes into a sort of swale down to the street. Only happens when flooding rain like Saturday night 3+ in about 6 hrs. May extend the piece out further from the house side.

Thank you and I agree that’s how it should be done from the start! Such a small investment could save a lot of headaches

Thank you as well! There was already a sump pit in place and it had the old clay tile drain pipe (built in 1954) which I tore out and new rigid plastic pipe, silt sock with plenty of gravel and tar paper on top before backfilling

Hilltop, that is a bit of MacGyver genius there using that water bottle to hold up the corner of the house!
