Identificação das principais patologias de fachadas em edifícios no município de Alegrete/RS

Abstract

The façade coatings of buildings, in addition to performing the function of protecting and give more durability to the building, also contribute to the property's value as regards the visual aspect as a whole. A damaged façade, in addition to devalue the property indicates that this presents constructive failures as well as lack of control and maintenance of the equipment. Within this context, this paper presents first, a study of the major existing pathological manifestations on the facades of buildings, followed by a case study in a housing estate in the city of Alegrete / RS consists of 12 multi-family buildings of standard medium / low finishing. This study aimed to present through damage identification cards and maps of incidence of damage, the main pathologies found through photographic records, as well as the main areas affected by the existence of pathologies in each façade of each building. Followed this analysis, a quantitative survey was done, the anomalies found in order to assist in the comparative study on the level of degradation of the facades of these buildings. Finally, after the study and analysis of the façades, it was found that the existing pathologies in the 12 blocks were always the same (cracks, mold / mildew, blisters, efflorescence and corrosion of reinforcement) in some blocks the presence of these were more intense and others less so. It was also found that the east and south façades and the roof slabs, were the places with the highest incidence of pathological manifestations. It found, finally, a decrease in the number of pathologies in the northern blocks compared to block further south, this factor, which is probably due to a difference in age between buildings.
