When paving a driveway, it is important to really understand what lies beneath it. We concentrate our driveway work in Portland, Vancouver, Salem, Gresham, and all surrounding areas in Oregon and Washington. Asphalt overlay is a cost-effective solution for a driveway. This process can only be used if the condition of the existing pavement will allow for it. A solid foundation is critical to the health and longevity of asphalt surfaces. Blacktop driveway overlays are very common for 10 to 12-year-old driveways. Some preparation is required at the garage apron and where the driveway meets the street.
