Architectural & Structural Concrete

When Robert A. Bothman Construction was founded as B&B Concrete back in 1978, we focused exclusively on architectural and structural concrete. While we have since extended our reach into many other market segments of the construction industry, architectural and structural concrete remain a cornerstone of our business. We are one of only a handful of certified pervious concrete installers in California, and have been recognized by the National Ready Mix Association and the American Concrete Institute. In addition, we are the sole distributor and installer of RABcrete™ pervious concrete, a revolutionary mix designed by our own research and development team. Today, we are known as one of the premier concrete contractors in Northern California and are quickly building a similar reputation in Hawaii. Our capabilities encompass:


  • Hillside & Estate Custom Foundations
  • Structural Slabs
  • Retaining Walls
  • Roads & Abutments
  • Floodwalls & Seawalls
  • Tilt-up & Cast-in-Place Building Structures
  • Curbs, Gutters & Sidewalks
  • Decorative Stamped & Colored Concrete Pavements
  • Pervious Concrete
  • Seat & Planter Walls
