Rapid urbanization in Brazil produces significant impacts on the quality of life. Rains have been one of the main problems faced by managers of the environment due to the sealing of large areas in cities. This work aims to develop of permeable interlocki ng flooring that can be used in many types of flooring, such as in outdoor areas of homes, plazas, parking lots, roads and pedestrian routes traffic light vehicle traffic. The study examined the permeability of concrete made from gneiss rock with grain size rema ins in diameters (4.75, 6.3 and 9.5) mm and (4.75 and 6.3) mm and uniform particle size of 6.3 mm and 9.5 mm mortar with varying content of 30%, 33%, 35%, 40%, 42% a nd 44%. Compressive strength mortar with content of 30%, 33%, 35%, 40%, 42%, 44% and 55% and abrasion resistance with mortar content of 40%, 42%, 44% and 55%. After analyzing the results of the tests, the concrete produced with mortar content of 42% and continuous particle size of (4.75, 6.3 and 9.5) mm which was attended abrasion resistance based on NBR 12041, the compressive strength based on NBR 9781 and permeability according to standard ACI 522 to R 06 interlocked with permeable concrete floor.
