Estudo das manifestações patológicas em fachadas de residências de alto padrão em condomínio fechado horizontal na cidade de Goiânia: Estudo de caso

Abstract

There are several studies related to pathological manifestations, but it is difficult to find studies related to high standard buildings in horizontal closed condominiums. In this sense, after observations when visiting these condominiums, it was possible to observe that there are pathologies on the facades of these residences. Thus, the objective of the work was to verify the pathologies on the facades of these buildings and analyze their possible causes. To carry out the work, a condominium was chosen, where a visual inspection was made on the facades of the buildings, relating the characteristics found in the literature with the characteristics found in the field, and thus being able to arrive at a possible pathology and cause. The Google Earth Pro application was also used to make a chronological analysis of the age of the buildings, through the images offered from previous years by the program. In the work, 412 buildings were analyzed, and almost 70% of these buildings had some type of pathology on their facades. Looking at possible pathologies and causes, it appears that 51.5% had infiltration stains on the drip tray and ledge due to humidity, 22.1% had fissures or cracks due to hygroscopic movement, 14.6% had efflorescence due to humidity, and 13.1% had cracks due to excessive deformation. In the end, it can be concluded that the percentage of buildings with pathologies increased with age, but there was also a considerable percentage of recent buildings that presented some type of pathology. In this way, it was understood that the possible reasons for the large percentage both in older buildings and in more recent buildings are due to the lack of qualified labor to perform the services, lack of daily technical monitoring, non-standardization of the services performed, use incorrect use of the materials, among other reasons. In some cases, older buildings had lower percentages than more recent ones. In this sense, the hypothesis is established that there was some intervention by these residents to make the correction, and thus, as the survey was carried out in the year 2023, it was not possible to identify which of these buildings underwent some type of renovation or modifications.
