    Stormwater management

    The proper utilization of pervious concrete is a recognized Best Management Practice by the U.S. Environmental Protection Agency (EPA) for providing first flush pollution control and stormwater management. As … See more

    Properties

    Pervious concrete consists of cement, coarse aggregate (size should be 9.5 mm to 12.5 mm) and water with little to no fine aggregates. The addition of a small amount of sand will increase the strength. The mixture ha… See more

    Testing and inspection

    Pervious concrete has a common strength of 600–1,500 pounds per square inch (4.1–10.3 MPa) though strengths up to 4,000 psi (28 MPa) can be reached. There is no standardized test for compressive strength. A… See more

    Cold climates

    Concerns over the resistance to the freeze-thaw cycle have limited the use of pervious concrete in cold weather environments. The rate of freezing in most applications is dictated by the local climate. Entrained air may help p… See more

    Maintenance

    To prevent reduction in permeability, pervious concrete needs to be cleaned regularly. Cleaning can be accomplished through wetting the surface of the concrete and vacuum sweeping. See more
