Founded by Archie L. Stamm in 1913, Stamm Contracting Company supplies ready-mixed concrete and contractor building materials from Mantua, Ohio, with delivery for projects ranging from small do-it-yourself jobs to larger construction work. Its specialty is the combination of concrete production, aggregate delivery, and contractor supplies under one roof, including decorative-concrete color and finishing products. More than a century later, the company says its personalized service, product quality, and integrity remain unchanged.
