Abstract

This paper objective is to contribute to the study of drainage of precast floor system, increasing the radius of joints of the concrete parts and, consequently, the percolation area existing between the floors, developing a drainage structure according to the NBR 16416. Made with a 9.40 mm shell, the paver had an 9.10% cast area, falling within the range of 7 to 15% recommended by the standard, when using hail as a grout, it was evaluated that this set has six times the minimum permeability coefficient recommended by the standard. It was found that this set has six times the minimum permeability coefficient recommended by the standard. Based on the results of the rainfall simulator, for a drainage area of 1 m² and a contribution area of 3 m², a rainfall for the metropolitan region of Goiânia with a return of 10 years, causing a flow of 148.5 liters per hour in the drainage area, would not cause surface runoff, even when extrapolating the flow to about 759 liters per hour.
