New Location!!

Canyon Rock has acquired Austin Creek Quarry in Cazadero, CA from Austin Creek Materials. We are excited to service the local community and the surrounding area with aggregate and concrete. We look forward to our new venture and working with our neighbors and the community. As our family is now in our fourth generation of this business, we are pleased to have Austin Creek and this community as a part of our future. One of our major objectives in purchasing Austin Creek Quarry is to maintain the small, family run plant that it is. In maintaining our objectives to protect the environment and minimize the local impacts, we hope to update all of Austin Creek’s equipment to surpass the current environmental regulations.

Upgraded Plant

We are always looking for ways to become more efficient and reduce our carbon footprint. We are currently in the process of upgrading our entire crushing, screening, and washing facility.
Benefits of our Plant include:

  • Enabling us to reduce equipment use and double handling material.
  • Motor control center utilizes the latest technology to reduce our power consumption.
  • Hoppers are lined with rubber tiles to reduce noise.
  • Screens utilize rubber panels which also reduces noise.
  • Fuel consumption has been significantly cut.

Filter Press

Here at Canyon Rock we strive to reduce our environmental impact. Last year we installed a deep cone thickener and filter press which enables us to recycle 95 % of our wash water. Our wash water comes from the process of making washed aggregate. We make many products through our wash plant from sand for concrete to double washed drain rock for septic systems. We have turned a waste product that was going to our ponds into a sellable product. This dry material can be used for pond liner or as a soil additive.
