I need to present method and materials to repair on the vertical surface of a chipped corner at the top of an exterior concrete foundation wall.
Previously, the exterior brick veneer had a 1" overhang outside of the face of the foundation wall, but due to mechanical damage, the foundation corner was chipped such that the brick now overhangs 2" to 2 1/2". The damage tapers down to normal about 8" down vertically from the top of the wall and about 12" horizontally from the corner of the foundation.
The brick and backup blockwork at the corner is damaged and will be removed and rebuilt as part of the process.
The issue that troublems me about just trowelling on a thin patch is that the patch needs to bear weight along the vertical shear surface, and the patch is so thin there is no way to get reinforcing/dowels into the detail.
We might also need to deal with marginally cold weather as the repair may take place in late March in New England.
We can impliment any amount of concrete removal to make this a more dependable repair, so I am tempted to just chop the entire top of the wall down some significant amount and pour a cap, but lesser approach advise would be welcomed.
