Estudo de caso: manifestações patológicas em sistemas de fachadas com revestimento cerâmico

Abstract

The facade ceramic coating system is widely used in buildings because of its performance and practicality. But to have a facade ceramic coating system that fulfills its aesthetic and functional role, it is necessary to perform periodic maintenance in order to fulfill 2 its design life. The analyzed building, São João Bosco building, is located at the Catholic University of Brasilia, Campus I, and it was possible to identify several pathological manifestations that were mainly caused by the lack of periodic maintenance. Among the pathological manifestations identified in facade ceramic coating system in question are: fissure; detachment; displacement; efflorescence; craving; Mold and mildew. The analysis of the possible causes of these pathological manifestations were cataloged in: lack of design that contains movement joints, drippings and desolidarization joint; Aperture of adhesive mortar cloth with time superior to the handle time requested by the manufacturer; Lack of yards and backsliders in the openings; And lack of periodic maintenance in the facade ceramic coating system. To remedy the causes of all these manifestations, in the current aesthetic condition of the facade, it is necessary to rework the entire facade ceramic coating system through an elaborate façade design taking into account good practice and current standards. It is worth noting that the cost for the implementation of a new facade ceramic coating system is much higher than the periodic maintenance costs along the design life, so the importance of periodic maintenance and surveys in the buildings is emphasized.
