Concrete floor slabs feature a stepped depression connected by either a construction joint or a control joint with a minimum six-inch dimension. The construction joint incorporates a continuous keyway with a tooled edge of one-eighth inch radius on each side, supplemented by dowels matching the slab reinforcing. The control joint includes a sawcut performed within the first twelve hours of the pour alongside a tooled edge with a one-eighth inch radius and matching slab reinforcing dowels. Concrete floor slab thickness and reinforcement are sized per the footing and foundation plan.
