Record dimensions of affected areas for _______.

• A. Spalling
• B. Cracks and potholes
• C. Spalling, scaling, decay, and delamination
• D. Delamination and decay

Answer: (C)

Recording the dimensions of affected areas is about quantifying how much concrete damage there is so you can assess severity, track changes over time, and plan repairs. In concrete deterioration, several distress types require measuring the extent of each patch: spalling (surface flakes off), scaling (loose surface material), decay (deterioration from moisture or chemical attack), and delamination (layers separating beneath the surface). These conditions create discrete affected areas, and their sizes directly influence repair decisions and needed materials. The other options are narrower or reference issues that don’t cover all the common deterioration modes that warrant area measurements.
