Concrete curb details on slab-on-grade illustrate two construction options for anchoring the curb to the concrete slab. Option A details a monolithically poured or cast-in-place curb with continuous number four rebar and hooked dowels extending into the typical slab reinforcement. Option B details a post-installed curb over a roughened surface interface, secured with number three epoxy dowels at twelve inches on center into the existing slab-on-grade. Both options detail continuous longitudinal reinforcing bars with increased bar counts for curbs wider than six inches, set below variable heights sized per architectural requirements.
