Fissuras em revestimentos de fachada: estudo de caso no Condomínio Las Vegas Salvador-BA

Abstract

Facade claddings do not always receive attention equivalent to their importance. This causes, over time, cracks to appear, which leave the facades with an unpleasant appearance, bringing visual discomfort to residents and visitors of the city, as well as may compromise the building with regard to watertightness, acoustic insulation, thermal insulation and smoothing of the surface in question. The general objective of this work was to analyze the causes of the appearance of cracks in facade cladding. In this attempt, an attempt was made to define and describe the different types of cracks observed in civil construction and, particularly, in façade coverings; verify the factors causing these cracks. In the development of this work, we used as a methodology the literary review and the case study, through which were analyzed the pathological manifestations that interfere with the mortar coverings of the facades of four residential buildings with multiple floors, located in Salvador-BA. A research allowed to conclude that the causes of cracks in facade coatings are: mortar shrinkage, structural deformation of the building, thermal variation, movement hygroscopicity and absence or deficiency of constructive details (project and execution, as well as the lack of maintenance in structural systems and elements).
