Founded in 1910 as Bradshaw Gravel Supply, Strata has been a North Dakota-based, family-owned company for more than a century. Over the years we’ve grown in services and size, but our commitment to quality has remained solid. Quality performance starts with quality people, and we strive to ensure a safe, hazard-free work environment. Each one of our employees attends annual safety courses to remain compliant with MSHA and OSHA regulations. We also perform location-based safety training, which focuses on the safety hazards of each individual site. With this team of dedicated, well-trained employees, we’ll continue our commitment to innovation while maintaining the quality for which we’re known.

Strata’s internal support division is based out of our new state-of-the-art facility. With scheduled maintenance to minimize downtime, we can guarantee our equipment is as dependable as our employees. Our full-time, year-round team of certified technicians is always working to ensure our vast fleet of equipment is ready to meet customer demands throughout all Strata divisions. No matter the job, we’ll be there when you need us.
