A IMPORTÂNCIA DA IMPERMEABILIZAÇÃO EM EDIFICAÇÕES - DESCRIÇÃO DA TÉCNICA DE IMPERMEABILIZAÇÃO DA LAJE DE COBERTURA COM MANTA ASFÁLTICA AUTO PROTEGIDA TOTALMENTE ADERIDA

Abstract

This work was designed with the purpose of demonstrating, through a case study, the application of asphalt blanket in order to waterproof the roof of a commercial building, thus solving the problems arising from infiltration through the slab. The work studied is located in the city of Varginha - MG. The main objective of the research, besides demonstrating the importance of waterproofing in increasing the useful life of the structures, was to prove the effectiveness of the system using asphalt blankets. As a specific objective, through the analysis of activities, demonstrate the correct application procedures according to the premises of ABNT BR 9574/2008. Through a study of the results, the asphalt blanket proved to be effective in completely eliminating the infiltration, results confirmed by the leakproofness test. The results also underline the importance of waterproofing structures in a preventive rather than corrective manner.
