Estudo de manifestações patológicas decorrentes de infiltração em município do interior do Ceará: diagnóstico e tratamento

Abstract

Infiltration is one of the main causes of the deterioration of public buildings, especially those with older construction ages. It is a phenomenon that occurs when water penetrates through building materials. Despite the technological and scientific progress in civil engineering, this problem continues to persist today. In this context, the main objective of this work is to diagnose the main pathological manifestations and evaluate the interventions carried out on walls affected by infiltrations in three public buildings in the interior of Ceará. The investigation was carried out through building inspections and data collection, using the ABNT NBR 16747/2020 standard. In addition, interventions were monitored and comparisons were made with the literature. The main pathological manifestations present in the buildings were related to infiltrations, with a higher incidence in masonry walls, in each building of the study. Such pathological manifestations found were: rising dampness, dampness by cracking, mold stains, blisters, detachment of plaster, and detachment of paint. The execution of the treatment was monitored for each building, and compared to the treatment adopted in the bibliography. Finally, it was possible to verify that failures or absence of projects, bad use of materials, and failure in execution favor the appearance of infiltration. Furthermore, the recurring demand for corrective treatment for the same type of manifestation is caused by errors in the execution of repairs.
