Estudo de viabilidade orçamentária para a substituição de manta asfáltica por membrana de poliuretano em serviços de impermeabilização em São Luís – MA

Abstract

This work has as its main objective the realization of a financial viability study on the execution of waterproofing services, utilizing polyurethane systems as an alternative to the traditional systems made of asphalt membranes in the city of São Luís - MA. This study was made by comparing the costs on the local market for implementing both systems. The usage of polyurethane systems are justified due to its lower installation time, greater elastic resistance, and it does not require a prior protection layer. The methodology consisted on literature review and field research, aspiring the fulfillment of the proposed objectives. The study was divided in three categories: literature review, market assessment, and data interpretation. The results obtained from the market assessment were unsatisfactory, once the interest for polyurethane waterproofing is still low on the local market, causing the labor costs to be high, becoming viable only on special cases which require fast implementation
