About this detail

A standard concrete masonry unit control joint serves courses both with and without horizontal reinforcement. Vertical reinforcement is placed on each side of the control joint per the CMU non-load bearing wall reinforcement schedule. Horizontal reinforcement is terminated two inches away from the control joint. A one-half-inch diameter by four-foot-long smooth dowel spans across the control joint, with bond prevented between the bar and grout using grease or a plastic sleeve. Alternatively, masonry control joint units may be used in lieu of dowels on courses without horizontal reinforcement.
