Stamped Concrete Driveway installed by Saint Louis Driveway & Patio in Affton, MO. Before Saint Louis Driveway arrived, this was an ordinary two car asphalt driveway. The customer decided to let us design a unique driveway that would distinguish their house from the average houses in the neighborhood. They wanted an approach to their home they could be proud of, and that will be a great investment should they ever decide to sell their home.
