Manifestações patológicas em habitações de interesse social de paredes de concreto em uma obra na Região Metropolitana de Goiânia

Abstract

The concrete wall construction system was first used in Brazil in 1979, but standardized in 2012. This system has been used by several construction companies to build housing units of social interest because of its characteristics, such as the reduction of costs and increased production speed. However, it is reasonable that with the desire for production speed, there may be a loss in the quality of the buildings that are delivered if there is no control in the entire design and construction process. Given this, this work brings a case study, in a work in the metropolitan region of Goiânia that used the system of concrete walls. In this study, the generic method of solving pathologies proposed by Lichtenstein was applied, listing the pathological manifestations found in 144 inspected apartments, with their due causes, diagnoses and possible therapeutic approaches to be adopted in each situation, with the help of photographic records and filling out inspection forms. It was seen that the origin of the manifestations found are endogenous and the highest percentage was due to execution, in addition to the fact that the highest incidence of repetition was cracking. The intention of this study was to identify the most recurrent manifestations and the origin of these incidences, to guide future works to avoid the appearance of possible pathological problems.
