Inject more water into the subsoil is very important, because when the ground water level is below capacity, causing settlements on the ground. Coupled with this, concrete recycling is an effective way to remove debris that pollute our soil. This concrete contains interconnected pores that allow water to pass easily. We worked with natural aggregates (NA) and recycled (AR) at 25 and 50% substitution. At 28 days of curing, the permeability, flexural strength and compression was evaluated. The results are linked together as the less permeable concrete obtained mechanical strength greater and inversely, on the other hand the use of AR caused a decrease in mechanical properties and aggregate shape was influential, crushed aggregate material which is a better link between the paste and the other aggregates.
