Abstract

Moisture is one of the most aggressive agents in buildings, which can generate unscheduled costs and compromise the performance conditions and durability of buildings. Thus, the proper use of the waterproofing system is essential for the prevention of pathological manifestations caused by humidity, which encourages research in order to better understand the influence of humidity on the deterioration of the constituent systems of buildings as well as the main techniques used. to ensure the water tightness of buildings. In this perspective, the present case study aims to carry out a qualitative and quantitative analysis of the main pathological manifestations caused by humidity in a public building located in Natal-RN, with emphasis on the evaluation of symptoms, origins, diagnoses, prognoses, and therapies. The results indicated that the execution and design flaws were responsible for the emergence of more than 80% of the evidenced manifestations, such as stains, mold, bubbles, detachments, fissures, and cracks. The flaws in the rainwater drainage project and the absence of the waterproofing project were decisive for the partial demobilization of the waterproofing system, resulting in the appearance of several points of humidity in the internal area of ​​the building.
