IMPERMEABILIZAÇÃO DE LAJES DE COBERTURA

Abstract

The heating of the building industry has been generating more and more the interest of the construction company and developer to generate more and more products in a smaller amount of time. With this we increasingly notice the appearance of pathologies in buildings. Das pathologies found in buildings, most of them are related to the system waterproofing. This, by the way, is one of the most important processes in building civil society, but it has been largely forgotten by cost cuts and / or misinformation of designers, generating more and more pathologies The repair of the waterproofing system when a failure occurs, it can be up to 15 times larger than when it was applied in the progress of the work. This study presents an analysis of various pathologies related to waterproofing and some methods used for correction. For the best In the reader's understanding, a survey of the main types of waterproofing process, indicating techniques of use, application methods, care in the application and constructive details indispensable in the process. Made a detailed analysis based on the main standard related to the waterproofing theme NBR 9575/2003, which indicates to the designer the main guidelines to consider. From there will be described two case studies analyzed by the author, in which one there was a constructive failure and that by a waterproofing error caused pathologies the structure. Were identified the problems in the waterproofing system and their possible causes and the step by step of how the problem was solved and in the other case a waterproofing project was made, which was applied during construction. After these studies were presented, it was A comparison of sealing costs between the two case studies is presented. Finally, a conclusion was drawn, presenting all the knowledge obtained in the work accomplished.
