Hallmark Spiral Parking Lot

Project Description

A previously abandoned concrete spiral ramp was the only access point to 130,000 SF of rooftop parking.  The conventionally reinforced ramp structure had severe corrosion requiring heavy structural repairs to slabs, beams, and columns.   The extensive corrosion necessitated an impressed current cathodic protection system.  The cathodic protection system utilized a titanium mesh laid on top of the existing milled deck that was overlaid with a 2” latex modified topping.   Special application methods were developed to eliminate electrical shorts within the cathodic protection system and place the LMC on the 17% slope.
