A concrete floor slab transition steps down with a sloped transition and incorporates a continuous keyway along the vertical face of the construction joint. Dowels matching the slab reinforcing span across the joint to maintain load transfer between placements. A minimum six-inch dimension applies to the depression zone, with slab thickness and reinforcing sized per the footing and foundation plan. Control joints require a sawcut executed within the first twelve hours of the pour alongside edges tooled with a one-eighth-inch radius.
