Also try to flatten out the bottom of the hole to create a stable level surface for the new patching material. I considered a lot of options. Use a hammer and chisel to remove loose concrete from the hole. The standard method of prelocating a hole in a poured concrete wall is to position a sleeve where the hole is needed.

You want the concrete surface in each hole to be perfectly. Press hydraulic cement into the hole with a small trowel or putty knife. If necessary fill the gap in layers of cement to build up the area slowly.
