Diamond Coring Co. Inc. is a mid-sized construction contractor based in Chicago, Illinois, serving the Chicago-land area with concrete cutting, coring, sawing, and related interior services. Founded in 1988, the company expanded its capabilities and market reach through a series of strategic acquisitions, beginning with Accurate Coring Co. in 1994 and including Greencastle Ltd. in 2000 and Concrete Cutting Edge in 2007.

These acquisitions broadened the firm’s portfolio and established its presence as a regional contractor in the Great Lakes area, capable of handling large contracts while attending to smaller projects with equal attention. In 2008, the purchase of Mass Grinding & Grooving/McLake Construction added high-speed grooving and grinding capabilities and the design and manufacture of associated equipment, enabling projects on an international scale. The organization emphasizes service quality and reliability as core attributes of its work, retaining a focus on customer needs across its market.
