ANÁLISE DE VIABILIDADE PARA TRÊS TIPOS DE IMPERMEABILIZAÇÃO

Abstract

Waterproofing is an important process in the execution of a work, as infiltrations can cause severe pathological manifestations. There are several systems of waterproofing agents available, as well as several products, but with the specifications and recommendations for each type of location and stage, and it is up to the consumer to choose the one which presents greater viability, of course you should also choose a system of waterproofing according to the place to be applied. The present work was developed with the proposal to compare, through a method of effective analysis, the application of three waterproofing. The general objective is to result in the best viability among three types of waterproofing, being the Asphalt Blanket, the Waterproofing Mortar and the Blanket of PVC. For this result, the AHP analysis method was used, made with the EXCEL software. The case study object is a parking area in the basement of a building, Residential Cipreste, in the municipality of Rio Verde - GO, with a total area of ​​2,351.4 m², however removing and excluding stairs and elevators, the area to be waterproofed is 2,326.9 m². It was considered if the direct contact with a large flow of cars, there is no direct incidence of the sun. It was obtained as result that Waterproofing Mortar, in the face of several matrices made within the AHP method, considering social, economic and environmental criteria and sub-criteria, is the most viable waterproofing agent for this case. The choice of this method of analysis (AHP) provides a reliable result with a good technical database for the execution thereof.
