No building collapses without warning. infiltrations, cracks and fissures are signs that something is wrong and only a specialist in diseases of the buildings may notice. The structural design of the building is essential part of the project, it identifies the work support needs, in addition to performing the normative analysis and design.
Professor of Civil Engineering of the Mauá Institute of Technology, J márcio. Estefano de Oliveira, It considers that the liquidator has a fundamental role in avoiding irreversible tragedies and misfortunes in construction, as, make visual inspection of the building, monthly or bimonthly. Importantly, this inspection should always start from the top down. The liquidator must apply for a technician to verify that the waterproofing is perfect, if there is perforated blanket or leaks in tanks, detachment of coatings such as floor and wall tiles.
The two main causes of leaks are: point of the hydraulic system and leaking sealing irregularities in ceiling slab. The conditions of this process are: humidity and dark spots on the wall, paint blistered, or peeling, cracks in the ceiling, loose tiles and presence of mold. The persistence of these factors will result in the penetration of water in the concrete, reaching the armor of iron and corrosion of the same. Thereby, the concrete will be pressed and cause the onset of cracks. concrete pieces fall, resulting in the exposure of hardware and its accelerated corrosion process. This procedure requires restoration in the affected part and sealing the infiltration, on an emergency basis.
The buildings tend to show little accommodation ground movements, may cause cracks and cracks in the walls in vertical and horizontal direction. Such defects may also arise as a result of climate changes.
In contrast, lot or rapidly developing, indicate that something serious could happen, requiring a survey for evaluation.
The marquees are more dangerous because they are not scaled to weight, in this case, water ponded rain can take it the total or partial destruction.
The Autovistoria Law determines that the inspection of residential and commercial buildings is performed every five years.
