I would recommend using a grout mixture made
with a hydraulic cement to plug the holes.

You could try forming the holes so that there is a revit in
the hole walls. Also, rebar as you suggested makes sense. The
revit will act as a shear key. Use expanding grout to ensure hole is
"full". I would also recommend roughening the surface of the hole

Subject: Holes through basement
I have a contractor who instead of using soldier piles use wood
vertical walls with diagonal wood bracings to support the adjacent
property. These wood bracings pass through the basement walls and
are spaced at 8 ft O.C. When the basement walls are poured
with concrete the wood bracings will create 6"x8"
holes. I didn't like the idea of using the wood bracings in
order to avoid those holes but I don't have any choice so I
just advised them to apply the details around the opening similar to
the one used for slab opening providing diagonal rebars to each corner to
control cracks. The holes will be filled with grout with the same
strength as that of the concrete basement walls. The basement walls will be
waterproofed as usual with drainage at the bottom to avoid water build up
against the wall.
I will appreciate anyone to point out what I missed in regards to
the holes created by the wood bracings.
Thanks in advance.
