Pervious concrete is a performance-engineered concrete with a 15-30 percent void system that allows rainwater to percolate through it. When pervious concrete is used for parking areas, streets, plazas and walkways, it minimizes stormwater runoff to surrounding streams and lakes, allowing for natural filtration to recharge local groundwater supplies. Moreover, because it reduces the need for stormwater drainage and wet pond retention systems, it promotes economical and beneficial land use.

Recent interest in green building and recognition of pervious pavements by the U.S. Environmental Protection Agency as a best practice for stormwater management have heightened interest in its use throughout North America. Installation of pervious pavement systems supports national initiatives, including Cool Communities and Low Impact Development, and provides a potential for credit in the Leadership in Energy and Environmental Design [LEED] rating system for sustainable building construction.
