Testing the product and placement in Service The Town flooded the Parking lot using a fire hose to determine if the Pervious Concrete had sections that were not Porous. The beams were broken and flex was examined along with the shear plains within the aggregate. Cores were examined for uniformity of placement. Once all, criteria were met the parking lot went into service 28 days latter.
