Audubon High School Grandstand
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.
