Abstract
This article aimed to show the application of a methodology for inspection of facades in buildings, based on pre-structured models. Three buildings with external ceramic coating were inspected, with the total inspected facade area of 4958 m2. By visual inspection, a survey of the areas of pathological manifestations by region and cardinal of the facade orientation was obtained, and the degradation levels were defined. Percussion test in the facades and water absorption and expansion by moisture tests in the ceramic plaques were performed. Relevant data concerning the buildings were obtained with interviews. The correlation matrix anomalies versus causes was elaborated, which allowed to assess the origin of the damage. Anomalies with greater occurrence in buildings were the stains and dirt and the deterioration in grouts. It was found the influence of the ceramic color and the position of facades on peeling. From the water absorption test, it was found that the ceramics of two buildings had high rate of absorption, and the analysis of facades regions showed that the absence of movement joints was one of the causes of peeling in the continuous walls and the transition between floors.
