ACI 318, ACI 546R, ACI 546.3R, ICRI 310.2R, ICRI 150.1R, ASTM C881, ASTM C928, ASTM C1202, ASTM C876, ASTM D4541, IBC Chapter 17

• Hammer sounding of all concrete surfaces to map delaminated, hollow, and spalled areas on elevation drawings.
• Crack survey classifying all cracks as structural or non-structural per ACI 224.1R with width and pattern measurement.
• Chloride penetration testing (ASTM C1202) and carbonation depth testing where rebar corrosion is suspected.
• Half-cell potential survey (ASTM C876) on parking decks and bridge decks to map active corrosion zones.
• Written condition assessment report with deficiency maps submitted before work begins.

• Remove all deteriorated concrete to sound substrate — minimum depth 1" beyond carbonation front.
• Methods per ICRI 310.2R: hydro-demolition (CSP 6–8), pneumatic chipping (CSP 5–7), scarification/grinding (CSP 3–5).
• Saw-cut all repair perimeters minimum 1/4" deep — no feathered edges permitted.
• Clean exposed rebar to SSPC-SP 6 minimum; apply zinc-rich primer and corrosion inhibitor.

• Apply bonding agent to all prepared surfaces.
• Place approved cementitious repair mortar; consolidate; match adjacent profile.
• Cure minimum 7 days with wet burlap or curing compound.
• Approved: Sika MonoTop 615/620, BASF MasterEmaco S 488, Mapei Planitop X, CTS Rapid Set.

• Engineer of Record (EOR) approval required.
• Provide shoring below repair area per EOR assessment.
• Install new reinforcement per EOR design per ACI 318.
• Place concrete per approved mix design (minimum 4,000 psi); cure 7 days minimum.

• Structural cracks (dry): low-pressure epoxy injection per ASTM C881 — ports at 6"–12" o.c.; inject bottom-up.
• Active water cracks: hydrophilic polyurethane foam injection first; epoxy after water is stopped.
• Non-structural cracks: rout 1/4" wide x 1/4" deep; install backer rod; seal with polyurethane sealant.

Apply anti-carbonation elastomeric coating at 2 coats minimum, 20 mil DFT, over all repaired and adjacent concrete. On parking decks: apply PUMA or urethane traffic coating per ASTM C957.
