About this detail

This concrete masonry unit wall detail shows a vertical control joint with a potential crack location aligned along the joint line. Every other horizontal bar terminates at the joint, except for roof and floor chord bars and lintel bars. The assembly specifies a minimum number five vertical rebar on each side of the joint or two number six bars at twelve inches on center. A backer rod and raked or concave joint filled with sealant seal the exterior. Open-ended bond units are used, and stacked bond is detailed at the cell adjacent to the joint.
