Corrosion in car‐parking structures

Synopsis The use of exposed concrete in car‐parking structures is universal. Even in steel‐framed structures, over 90 per cent of the construction material is concrete and the only variation is whether it is precast, prestressed, or ordinary reinforced concrete. Having inspected more than 50 parking structures over the past 17 years, the author has seen many buildings where defects have repeated themselves time and again and where problems which appeared to be of minor import to the original designers and builders eventually developed into major defects.
