About this detail

A concrete masonry unit wall control joint features specific detailing for courses with and without horizontal reinforcement. Vertical reinforcement is placed on each side of the control joint per the masonry non-load-bearing wall reinforcement schedule. Horizontal reinforcement is terminated two inches from the control joint. A one-half-inch diameter by four-foot-long smooth dowel spans across the control joint with a grease or plastic sleeve applied to prevent bond between the bar and grout. Alternatively, pre-formed masonry control joint units may be used in courses without horizontal reinforcement.
