BUILDING QUALITY SINCE 1964 T∙A∙H Construction was originally incorporated in 1964 by Henry Toews, Theodore Ayres and Irvin Huber. These gentlemen set a mandate to serve the construction industry with their unique engineering capabilities. The T∙A∙H reputation grew and they became know as the builders with engineering "know-how". Providing the knowledge, service and quality buildings in the commercial, industrial, institutional and community markets, clients returned time and time again to build more projects.
