For larger areas, the contractor installed cathodic protection anodes and then filled all repair areas with two-component, fast-setting, polymer-modified, cement-based mortar. In addition, crews applied both a three-component, epoxy-modified, cementitious structural resurfacing compound and an elastomeric, crack-bridging, anti-carbonation acrylic protective coating to the exterior of the entire structure.The restoration earned a 2012 ICRI Award of Merit in the Historic Category.
