Founded in 1951, the Concrete Technology Corporation was the first prestressing factory building in the United States. After winning acceptance of its structural concepts, the company grew both in sales and product demand. This resulted in the expansion of its Tacoma, Wash., plant in 1960. A second major production building was added in 1967 to accommodate the rising demand for precast building elements. In the 1970 s, its product expansion included facilities for semi-automated casting of hollow-core slabs and construction of floating concrete structures. Since the company s inception, literally thousands of bridges, buildings, piers, tanks, floats and other structures throughout the Pacific Northwest and Alaska have been built with Concrete Tech products.
