About this detail

These structural details illustrate slab-on-grade joint configurations, including curb transitions and thickened edge conditions over a prepared subgrade per the geotechnical report. The main slab rests on the subgrade and transitions into a depressed or elevated curb section with a maximum depth of 8 inches, reinforced with continuous number four rebar and ninety-degree standard hooks. A six-inch concrete wall includes number four reinforcing bars spaced at twenty-four inches on center each way, supplemented by two continuous number five bars at the slab intersection. Additional perimeter conditions feature continuous horizontal reinforcement and specified concrete clearances of three inches. General notes require contractor approval for joint locations from the architect or engineer, adherence to ACI standards, and a maximum slab aspect ratio of 1.5 to 1.
