Concrete is a very durable, strong and long-lasting material which is why it’s used in foundations of buildings, as roads and driveways, and as floors, patios, etc. However, after years of exposure to the elements and disuse, concrete will break apart and crumble, leaving evidence of its form, but no longer standing or whole. Under certain circumstances, concrete can become deteriorated and distressed. Spalling, scaling, and cracking can diminish the appearance and functionality of the concrete structures resulting in occupant complaints, hazards, and increased maintenance. If left unchecked, these conditions can lead to structural or performance failures requiring extensive and expensive repairs. Assuming that the developer has used a good building design by a qualified architect, that he has used good quality cement and steel, and that the foundation is adequate for the type of soil in the plot, a multi-storey apartment building will provide problem-free service for anything between 70-80 years or even longer. Within this period, regular maintenance of the building’s structure will need to be carried out, which a responsible developer who considers himself accountable for his products will undertake as a matter of course. A badly constructed building which falls into neglect after all the units are sold may not last for more than 35-40 years before developing serious faults, along with all related dangers to the occupants.
