Concrete slab threshold reinforcing details for exterior and interior door openings feature diagonal reinforcing bars centered within the slab thickness. The layout incorporates a forty-five degree angle orientation extending three feet typically from the door opening edge. A control joint or construction joint intersects the slab edge adjacent to the opening. Reinforcing bars are oriented in the opposite direction of the slab edge or joint.
