Impermeabilização de lajes de cobertura: caracterização, execução e patologias

Abstract

This study has as its theme the waterproofing of roof slabs, characterization, implementation and pathologies. Although sealing is a very important stage in construction, it is often second plan by the builders and architects, creating many problems in buildings. The intention of this work is to reinforce the importance of making a waterproofing system suitable for roofing slabs in order to prevent damage caused by infiltrations. Through a bibliographical study, the importance of having a waterproofing project that meets the requirements according to NBR 9575 (ABNT 2010) will be reinforced. The types of materials that are available in the market will be introduced as well as the use of each of them. We will present examples of how to properly apply a waterproofing system with blanket. And lastly is also presented a study on the possible pathologies caused by infiltration, as well as the pathologies arising from the lack of a waterproofing project or failures in its execution.
