We process and deliver quality Aggregate products from Pit Run to Rip Rap for use in landscaping, drainage, road building and maintenance, and much more.

We service Mendocino, Lake, Sonoma, Colusa and Humboldt Counties. From coastal to inland California. We provide quality Aggregate and Rock Slope Protection to California State Parks, Cal Trans, City of Ukiah, City of Willits, Mendocino & Lake County DOT and our community.
