The surface condition of the protective rust patina is a good indicator of performance. An adherent fine grained rust patina indicates that corrosion is progressing at an acceptable rate, whereas coarse laminated rust layers and flaking suggests unacceptable performance. Other signs to look for and areas to investigate during visual inspection include: – Leaking expansion joints. – Accumulation of dirt or debris. – Moisture retention due to overgrown vegetation. – Faulty drainage systems. – Condition of sealants at concrete / steel interfaces. – Excessive corrosion products at bolted joints (“pack rust”).
