Me again. The guy with the uneven basement walls and XPS going up (which I am going to film / document)

NE Ohio. 1940s House. Cinder block basement.

As I'm cleaning up the wall for the XPS to go up, I'm removing lots of lose DryLok. Probably years of it.
In the process, I'm realizing that most of the 'bumps' are large or small patches of concrete into the foundation.

However, there are several places where removing the drylok is exposing cracks with air coming thru them. A few run along mortar lines and are thick enough to get a knife edge into. A few are even holes (finger).

These are both above and below grade in cinderblock. Obviously, the holes aren't filled and air is getting in the top and running down somehow.

I put some great stuff in most last night deep into the cracks. Should I throw in some hydraulic concrete (its what I have laying around), caulk the lines and cover? Just repaint with drylok and be done with it?

Starting the XPS going up in the morning, so want to shore up the wall part by tonight.
Any input appreciated.

Post a picture.
Foam is not water proof and should not have have been below grade.
This really sould be sealed on the outside not the inside to do it right.

Thanks for the response.
To clarify: No water issue on this wall in the basement.
The issue is air coming through cracks - which I am wondering if I should treat as structural (add cement) or just fill the gaps and move on.

Ran a 7d test with plastic sealed to exposed cinder - zero moisture.

House is waterproofed from outside. (Apparently one of the only things that turned out to be true when we bought the house...but that's another story...)

Which direction are the cracks running? How long are they? How wide are they?

These may be indicative of larger structural issues.

And in the spring water will follow the below grade cracks.

And then he asks himself..."do i even want to keep asking questions?" :censored:

So irritated right now.
Thank you ALL so far for the input. Your input is very valued, and good to keep me asking the right questions.

I will update with some pics of the cracking.

The "inspector" (he turned out to be an idiot of sorts) noted that the wall had indeed shifted over the years, but that it was stable and there were no issues. The waterproofing (full dig out, gravel backfill) apparently stopped any movement.

Like you said, though, Canarywood - where there is air, there can be water.

This was just a simple ManCave / Music Studio project a few weeks ago. Now I'm +$500 on budget and not enjoying a single flippin moment. Irritated, frustrated. Ok, rant mode: off.

Hang in there,there's a fix for everything,hydraulic cement will last for a few years until there's movement,but epoxy or polyurathane will be a permanent fix,stuff is a little pricey but it's a once and done deal.
