Análise técnica da implementação de um sistema de impermeabilização em edificação pública: estudo de caso em uma unidade básica de saúde

Abstract

Waterproofing is an essential component of civil construction, particularly in buildings, as its primary function is to protect structural and non-structural elements against moisture and water infiltration. The incorrect selection of the waterproofing system, inadequate execution, or the use of products that do not meet the project's technical requirements are common issues in construction works. This study aims to technically evaluate the waterproofing system applied to a Primary Health Care Center (PHCC), considering regulatory requirements, technical specifications, and cost aspects. The adopted methodology consisted of a literature review, standards analysis, and a case study conducted at a Primary Health Care Center located in the municipality of Carmo do Rio Claro, Minas Gerais, Brazil. The results indicate that foundations, slabs, and wet areas are the building elements most susceptible to infiltration problems, with improper material selection and poor workmanship being the main causes of pathological manifestations. It is concluded that proper technical specification, compliance with Brazilian Association of Technical Standards (ABNT) requirements, and the qualification of the workforce are fundamental to ensuring the durability and performance of buildings.
