Wilkinson Precast Inc. is a family owned business that has been manufacturing quality precast concrete products since 1953. Many of our original structures are still in service. Our Riverside, Iowa plant serves Iowa and the surrounding states. We specialize in quality solutions with concrete products that help the environment. Years of experience in large water, waste and utility structures mean that Wilkinson has built a repertoire of unique solutions to many problems of design. We know and appreciate that our customers depend on our quality service and understanding of their requirements.
The Wilkinson's have over 55 years experience manufacturing quality pre-cast concrete products. In 1994, Wilkinson's started a new facility in Riverside, Iowa, offering the only septic tank in Iowa to meet ASTM structure and design at that time. Water tight one piece design. Our 500, 1000, 1250, 1500, 1750, are seamless one piece tanks, SEALED AT PLANT. Installed quickly. The partition is monolithically cast right into outer walls and tied together with rebar. These tanks are STRONG. Our high quality forms produce the heaviest tanks on the market; most other manufacturers do not have the crane capacity to meet Wilkinson's standards.
