Diamond Companies

Diamond Coring Co. Inc. was founded in 1988 providing outstanding customer service throughout the Chicago-land area. This outstanding service approach led to its first acquisition of Accurate Coring Co. in 1994, an industry pioneer with a 35-truck operation that dominated the Midwest sawing and drilling market since its 1973 inception. As the hard work persisted, Greencastle Ltd. (Indiana) was acquired in 2000 and in 2007, Concrete Cutting Edge (Chicago-land), was acquired to bolster Diamond Coring Co. Inc. interior service revenues.

Through acquisitions, hard work and persistence, we have distinguished ourselves as a leader in the Great Lakes region. In 2008, we acquired Mass Grinding & Grooving/McLake Construction, a company that has revolutionized the concrete profile grinding and airport runway grooving industries with the design, engineering and manufacture of high speed grooving and grinding equipment. This industry segment expands our capabilities to an international scale having completed projects across the globe.

While we possess the resources, capabilities, bonding and qualifications to perform the largest contracts, we consider no job too small. We believe that every project deserves our utmost attention and our commitment to provide outstanding service. Contact us today!
