Re: 12" Block Wall Repair

Are you saying that the 40' x 12' high CMU block retaining wall has no reinforcement or concrete fill? If so, this is almost impossible to imagine. The buckling you describe should be fully repaired. Ideally, you'll need vertical rebar to be drilled and epoxied into the existing footing, assuming the existing footing is sufficient for the conditions. The spacing, placement and size of rebar should be determined by a structural engineer depending on the expected load to be carried by the wall. Furthermore, usually horizontal rebar is required as well. This may have to be inserted from the ends and pushed into place on every course or every 2nd course. A soupy grout should be used to fill the wall solid, making sure that the grout reaches all the way to the bottom without voids. You may need to use a vibrator to help consolidate the wet grout. Given the height and extent of this retaining wall, we strongly urge you to consult a structural or civil engineer who can assess your conditions first hand and recommend an engineered solution to your problem.
