Two concrete curb details illustrate narrow and wide configurations cast on top of a concrete slab with a metal deck. The narrow curb variant features a width between four and eight inches, reinforced with number four continuous bars at the top and mid-height, alongside vertical number four adhesive anchors spaced at twelve inches on center with a three-inch minimum embedment. The wide curb variant, measuring eight inches or greater in width, incorporates number four continuous bars at each face for both the top and mid-height positions. Both details indicate an intentional rough surface or keyway at the cold joint interface between the curb and the supporting slab.
