Audubon High School Grandstand

Project History

Audubon High School grandstand was built in 1936. Physical wear, corrosion of steel reinforcing, deicing salts, acid rain and freeze/thaw cycling all played a role  in spalling and deterioration of concrete surfaces.  The architect, structural engineer and school district formulated a repair strategy designed to restore the  structural elements, update the appearance and  incorporate protective measures to extend the useful  life of the stadium. Extensions to widen each of the steps  on the main stair aisles were poured to bring them up to  code. Conpro Primer was applied first to the existing  concrete to improve adhesion. Once the repairs were  complete Elastideck and Super Color Stain HR system  was used on the treads and risers to prevent water entry.  Color Coat was used to coat the soffit of the grandstand,  concrete columns supporting the grandstand and  the various knee walls around the grandstand.
