EFFECTS OF CRACKS ON A BUILDING

A crack is a complete or incomplete separation of concrete into two or more parts, produced by breaking or fracturing of a concrete wall, foundation and other parts of a building. The appearance of cracks is a symptom of distress within the fabric of the building. Often the cracking is of little consequence and once it is established as static, it gradually increases which maybe the first sign of a serious defect which may affect the serviceability or the stability of the house. Cracks have become an indigenous, undesirable feature in both the old and newly constructed buildings. After completion of a building, unexpectedly cracks begin to develop on the walls, foundations and floors which weaken the strength, stability and eventually its durability. It is most probably that, cracks that are not properly identified and paid attention to may lead to collapse of the structure. Although the craftsmen take actions to minimize cracks during the building process, it is rarely possible to avoid them entirely. Not until possibilities are found to reduce or avoid this phenomenon, clients and craftsmen will keep on facing big economic lose. What could be the cause of these cracks? How can these cracks be reduced or avoided? Contributions of ideas and skills on; understanding, minimizing/reducing and avoiding cracks destroying buildings are welcome from well-wishers and craftsmen.
