Schuster Concrete ships what we call Ready-Mixed Concrete. When you place an order for concrete we match your requirements with a specific mix design from our database. The mix constituents are sent to batch panels that load all the raw materials into a drum which mixes the concrete. By the time the truck arrives at your job the product is sufficiently mixed and ready to pour. Each load is custom made for your application according to a specific mix design only moments before the truck leaves for your home or job. The batching of the raw materials in their specific quantities is done by computer, guaranteeing accurate products and reproducible mixes.
