ESTUDO COMPARATIVO ENTRE MANTA ASFÁLTICA E ARGAMASSA POLIMÉRICA EM PISCINAS

Abstract

Infiltration is still an important issue in civil construction. Through technological advances, the market has made several solutions available to treat various problems that cause this pathology. These products are widely used in Brazilian construction sites. In fact, there is a large volume of effective solutions, but there is a lack of technical knowledge on construction sites. This study presents a detailed and technical analysis of two waterproofing systems widely used in Brazilian civil construction: asphalt membrane and polymeric mortar. This work is extremely relevant for civil engineers, as it addresses the importance of waterproofing in the durability and functionality of structures, especially in swimming pools, which are subject to significant hydrostatic pressures. The study was conducted through two practical cases, where each system was applied to reinforced concrete pools, allowing a direct comparison in terms of execution steps, application time, cost and efficiency. The results indicate that, although the asphalt membrane offers greater flexibility and is faster to apply, the polymeric mortar stands out for its significantly lower cost and for not requiring additional mechanical protection, which can be a decisive factor in many projects. The conclusion of the study suggests that the choice between the two systems should be based on a careful analysis of the specific conditions of each project, considering factors such as cost, execution time and flexibility requirements. This work not only provides a solid basis for making informed decisions, but also highlights the importance of strictly following technical standards and manufacturers' recommendations to ensure the effectiveness of waterproofing. For civil engineers interested in deepening their knowledge of waterproofing techniques, this study offers valuable and practical insights that can be applied in future projects.
