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. Aggregates are the most mined material in the United States. We focus on safety and efficiency when producing our Aggregates that are used to build our infrastructure and our communities.
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. If you have a landscaping project we encourage you to stop by and take a look at what is available to put your vision into place.
We look forward to working with you. No job is too big or small.
We employ experienced and highly skilled staff in the aggregate industry including geologists, mining and civil engineers. Northern Aggregates rock materials from the Harris Quarry are used on State or Federal Highways in Mendocino County. We work regularly with all cities in Mendocino and throughout the county on emergency relief work, disaster prevention, and ensuring materials for community emergencies such as floods, fires, and earthquakes are readily available.
We are located in Mendocino County just west of Highway 101, 15 minutes North of Ukiah, and 5 Minutes South of Willits. Harris Quarry has been owned by Northern Aggregates, Inc. since the 1980s and has been mined off and on since the 1920s.
