Parking Lot – Columbus, Ohio


This office building in Columbus, Ohio, housing Nationwide Insurance and managed by Duke Realty was just 8 years old and in great shape except for the parking lot which was looking more like 25.
IRS Consulting Inc. evaluated the parking lot and drive way and concluded that drainage was a large part of the problem and the solution. Drainage was missing or inadequate along the high side of the lot where water was infiltrating from a hillside. It had been installed below the hardpan level where water couldn’t reach it along the boulevard.
A J Asphalt Maintenance & Paving Co. tore back a band of pavement and installed 12-inch Multi-Flow along the high side of the lot to intercept the infiltrating water. They also installed Multi-Flow along the boulevard, placing it at a more effective depth.
