About this detail

A concrete topping slab bears on a structural slab, concrete on steel deck, or structural wall and beam, with waterproofing, insulation, or other layers placed per architectural specifications. Reinforcement is placed at one-third the depth from the top of the slab per Table A, alongside control joints aligned with typical slab-on-grade details. Around the perimeter of the topping slab, number 4 bars measuring two feet long are drilled and epoxy-anchored into the primary structure at forty-eight inches on center, or provided as cast-in dowels at post-tensioned slabs.
