“We have been working with Northgate around 8 years now, every pour we have with them is always on time, a quality product and great service. Northgate always takes care of us no matter what the circumstances are or how complex the project might be. They will service your small 3 yards projects just as well as they will your 500+ yard project. Northgate is the way to go, there is no other competition.”

“Granite Construction used Northgate Ready Mix for all the structural concrete, over 1,000 CY’s, and flatwork placed on the Healdsburg Avenue Bridge Retrofit. The people at Northgate Ready Mix really know what they’re doing and provide great service. Their service and attention to detail have made things easy. They’re a great resource to have during construction. Well organized, informative and most importantly delivered quality concrete on time.”
