Análise das manifestações patológicas em drywall

Abstract

With the advancement of global technology, all commercial areas have been modernizing and introducing techniques, products and demands. In this context, the construction industry has been marked as one of the sectors least receptive to change. However, although still somewhat receptive, some areas already have new construction methods. One example is the replacement of traditional cement mortar and ceramic brick walls with Drywall walls in internal partitions, partially or totally in some buildings. Another example is the replacement of traditional and common plasterboard ceilings with ceilings with structured plasterboard panels. Observing this, it was noted that the city of Crateús in the state of Ceará already has some buildings in use and under construction that use this system and it was also noted that there is a lack of studies that analyze the quality of the service execution and the condition of the elements executed. Thus, the objective of this study is to evaluate how Drywall walls and plasterboard ceilings are being executed in a building under construction, as well as to evaluate the pathological manifestations found in these elements in two buildings already in use. The buildings are located in different parts of the city, and were chosen based on the degree of importance and rate of use of the elements of interest in the total composition of the constructed area. The evaluation was carried out through technical visits and data collection at the sites, using a methodology that allowed directing the various stages of the work, ranging from the selection of buildings to the survey of their history (namnesis), inspection and diagnosis. In the building under construction, the methods of execution of the partitions and ceilings were analyzed and compared with the guidelines of technical standards and manuals of material manufacturers. In the buildings in use, the pathological manifestations found were proven and possible causes for them were proposed, also in accordance with technical standards and manuals of manufacturers, as well as recommendations for correction. Finally, based on the results of the tested buildings, an assessment was made of the quality of the services performed, defining a classification for them and extrapolating this classification to other buildings that use this construction system in the city.
