Concrete slab-on-grade conditions include a depressed slab transition and a thickened slab edge. The depressed slab detail accommodates a maximum four-inch depression with two continuous number four reinforcing bars, incorporating ninety-degree hooks at the step when the depression depth exceeds two inches. The thickened slab edge detail features a twelve-inch minimum depth below finished grade or paving, an eight-inch minimum base width, and a one-to-one sloped transition back to the main slab thickness reinforced with two continuous number four bars.
