Abstract

Watertightness is one of the main requirements for the proper performance of construction systems, recommended and measured at various levels by NBR 15575/2021. Against this background, the development of an appropriate project and the use of accurate materials and techniques are essential to ensure the perfect functioning of the systems, as well as to guarantee their durability. The target was to inspect the implementation of waterproofing services in an endeavour located in the city of Goiânia, which provided a case study of the executive methods of three different typologies of a waterproofing system. Therefore, the waterproofing projects were studied with the aim of diversifying the methodological combinations the entire system, as well as analyzing the starting conditions, the sequential stages of service, the materials used and how they were applied, the execution and inspection of services. All of this, if necessary, in accordance with the company’s quality control tools and normative prescriptions, executive procedures (PEIS) and service verification sheet (FVS) that meet the specific requirements of the adopted waterproofing types.
