Mid State Concrete Products

We are committed to the highest standards of workmanship and customer service. Founded in 1975 by Ralph and Pat Vander Veen, Mid State Concrete Products LLC began as Mid State Septic Tanks on an empty one-acre parcel in Grover Beach, California. We began manufacturing septic tanks with six septic forms, one delivery truck, and one employee. Over the years, scores of products have been added to the production line, along with the capability to engineer and produce custom made products. In 1977, the company incorporated and became Mid-State Concrete Products, Inc. With more work space, we began adding new products and put our own batch plant into production. In 2020, we were licensed to manufacture Pole Base to help diversify our precast business. Mid State Concrete Products manufactures a comprehensive line of precast concrete products including PG&E utility structures and transformer pads, Redi-Rock retaining wall systems, septic tanks, manholes, commercial and industrial waste system structures, catch basins and curb inlets, burial vaults, highway barriers (K-Rails), site amenities and many other custom and miscellaneous concrete products.
