About this detail

A non-bearing concrete masonry unit wall bears on a cast-in-place concrete footing with a slab on grade. Three continuous number four reinforcing bars are placed within the footing, and vertical dowels matching the wall reinforcement with standard hooks extend upward into the CMU cells. The concrete surface at the cold joint is cleaned and roughened to a one-quarter inch amplitude. Wall intersections and corners detail single and double layers of reinforcement with number five vertical bars, standard hooks at inner corners, alternating bend directions, and lap splices as required. Face shells may be removed with open end units full height at wall intersections typically.
