Need a picture from further back? More info.

This portion will be for the garage. Garage door will sit in this (footing below) foundation. I am waiting for them to strip the remainder of the stem wall to see if this "crack" goes to the top and the other side (through).

If it is just one side, would this be acceptable?

some info that might be helpful - http://www.cesinspectionstexas.com/concrete-honeycomb/

This, from this angle, looks kinda of weird. Need more info.

Was it poured during freeze? It looks like someone patched but not sure. You need to get definitive answer on it. Photo of J-bolt area may be helpful.

This is for the garage. Backfill and slab will go on.

That surely needs some work, IMO. When a seam of a "crack" goes all the way down like that, never a good sign. I would find a concrete expert to take a personal look. Photos can be deceiving. It's possible a "patch" will be sufficient in this area, but I would kind of wonder if more isn't needed. Sure needs to have sufficient water repellant applied to exterior before any backfill.

As Home Probe said, this is a step-footing transition between the basement and garage and most likely they started to pout at that location, and this is the transition between the two batches of concrete where they tried to form one mass under vibration, but sometimes especially in these places it is much harder to achieve that.

If that is a cold joint, in most "cold joints" gaps in the concrete are merely seams containing no voids and in most cases they're linear, closely joined and bonded. That being said, in some situations, there is a possibility they will have small voids where concrete is not fully compacted, as with any concrete pour.

Generally, cold joints are not a structural problem if the joint is under static conditions, in addition, most likely "parging" with be done in that area and waterproofing will be applied.

Ok okay, I got a good look and spoke with my contractor who said this:

"We will patch it so no water penetrates to the rebar but other than that it will be fine. It's a cold joint where we ran short that day and finished up the next. Structurally it's fine and also it's just the wall under the garage door so doesn't bear any weight, just ties the two sides of the garage together".

Home Probe - thanks. Yes, fill will be brought in (balanced on both sides) up to the frost line.

GN Builders L.L.C - thanks. Yes, it will be in a static condition when completed
