Reinforced concrete structures are designed and built to function for a certain period of time with as little maintenance as possible.  In benign environments and when use is as intended, this most likely can be the case.  The structure achieves its service-life with little-to-no major repairs needed.  However, as structures age and deteriorate we are faced with the need of extending their service life beyond their original design lifespan by repairing them rather than replacing them.
