Slab-on-grade recess configurations accommodate both greater-than-slab-thickness and less-than-slab-thickness conditions. The recessed slab incorporates continuous top and bottom reinforcing bars, such as two number 4 bars, alongside number 3 dowels spaced at 18 inches. Dowels match the size and spacing of typical slab reinforcing with a lap length of 48 bar diameters. Dimensions indicate an 8-inch step or width constraint, with a maximum recess depth sized per plan up to 30 inches.
