Cadman makes aggregates for every type of construction project - no matter what the size. We supply aggregates for everything, from large commercial to home-improvement projects.

In addition to materials for new construction, Cadman recycles excavated dirt and old asphalt and concrete. We crush and size it to make usable products - instead of filling up landfills. We market recycled glass, which is great for drainage gravel and wall backfill. Backhaul sites that accept clean fill are located at Black Diamond and North Bend.


For more information on what is defined as acceptable backhaul or to find a site that accepts this product, please contact our dispatch office at (425) 961-7100.

We Supply:
  • Crushed aggregate for highway bases, driveway rock, railroad ballast, and backfill
  • Washed aggregate for septic and drain rock, concrete, pipe bedding, and parks
  • Bank-run sand and gravel for structural fills
  • Rockery (1-5 man rock)
  • Slope protection rock
  • Silt and runoff environmental controls
  • Recycled concrete and asphalt
  • Golf course and playing field sands
  • Growing medium sands
  • All weather sands
