A concrete floor slab transition steps down with a minimum six-inch dimension, reinforced by dowels matching the main slab reinforcing. The construction joint features a continuous keyway and edges tooled on each side with a one-eighth-inch radius. The control joint incorporates a sawcut executed within the first twelve hours of the pour alongside a tooled edge with a one-eighth-inch radius. Both slab segments are sized per the footing and foundation plan.
