AGGREGATES
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, Gold Bar, Granite Falls, and North Bend.
BACKHAUL IS ACCEPTED ON A CASE BY CASE BASIS ONLY.
Any source site is required to provide a Site Specific Fill Declaration prior to backhaul arriving at any of our sites. 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.
