Exterior Renovations to Cassell Coliseum

Cassell Coliseum

In May 1997, an exterior renovation project began on a well-known and architecturally distinctive facility located on the campus of Virginia Tech in Blacksburg, Virginia. The renovations were prompted by spalling concrete, rust staining, and a desire to upgrade the appearance of this popular facility. The existing cementitious coating on the flying buttresses was discolored by mildew stains and dirt, and had not prevented the corrosion.

The repair and protection strategy at Cassell Coliseum included the removal of all unsound, deteriorated, spalling, or delaminated concrete; partial removal of steel chairs and/or ties close to the surface; application of an epoxy-modified/ cementitious anticorrosion coating/bonding agent in repair areas; application of a high-build, two-component, polymer-modified, cementitious repair mortar to fill the spalls or delaminations; and application of a decorative and protective anti-carbonation coating, proven to resist the future ingress of carbon dioxide gas.
