C.S. Mundy was one of the pioneers of the commercial stone crushing industry in western Virginia. Mr. Mundy operated quarries at several locations in the Shenandoah Valley through the 1930's and 40's. 

Along with his two sons, Mr. Mundy started what are now the Broadway Quarry and a quarrying operation on Route 602 west of Elkton, Virginia. In 1946, the Mundy acquired the lease on the Flatrock Quarry. The Commonwealth of Virginia first mined the Flatrock site in the 1910's or 20's using convict labor, but the site had been inactive during World War II. 

C. S. Mundy Quarries became a corporation in 1954 and moved into a new rock office building at the Broadway facility in 1956. The company grew and flourished through the '50's, 60's and '70's supplying crushed stone for many of the major construction projects in the area. The Elkton-area quarry was sold in 1977. In 1981, Valley Blox, Inc. of nearby Harrisonburg, Virginia, acquired C. S. Mundy Quarries, Inc. Valley Blox is the premier manufacturer of block and precast concrete structures in Virginia and the largest area dealer in general building supplies. All Valley Blox block and precast concrete is produced using Mundy aggregate. 

Mundy Quarries has continued to expand. In 1988, a new $1.3m state-of-the-art crushing plant was built at the Flatrock Quarry. In 1989, an asphalt plant was placed at the Flatrock Quarry. The plant is owned and operated by Blackrock Contracting, a Division of Adams Construction. In 1996, the Broadway Quarry plant was upgraded and automated. Also in 1996, the capability to sell stone by metric weight was added at both quarries. 

In 2007, Valley Blox underwent reorganization. As a result, Mundy Quarries is now a direct subsidiary of the parent company, Eagle Corporation. This change allows Mundy Quarries to work directly with other Eagle Corporation aggregate companies to more easily share knowledge and technology about production, safety and protecting the environment. 

In early 2008, Mundy Quarries acquired the lease to operate Star Tannery Sand located in the community of Star Tannery in Frederick County, Virginia. This facility gives Mundy Quarries the capability to produce a high quality natural sand for use in concrete and asphalt as well as sand for landscaping and golf courses.

In the fall of 2010, we took the step to consolidate our operations as a result of the economic climate which has allowed Mundy Quarries to focus our efforts in to our flagship quarry at Flatrock. This move has allowed us to maintain our market and continue to provide customer service with both delivery and pick-up from this central location.

In addition to Blackrock Contracting, a Division of Adams Construction, other major commercial customers are Rockingham Ready Mix of Mount Jackson and Luray, Virginia and Cumberland Concrete of Baker, WV. The Virginia Department of Transportation (VDOT) has long been the largest source of demand for Mundy Quarries products. Road repair and construction projects require large amounts of aggregate material. In 1994, Mundy Quarries also became certified as a supplier to the West Virginia Department of Highways (WVDOH) and has supplied several significant WVDOH projects. Mundy Quarries carries a complete selection of both VDOT and WVDOH certified aggregate products. 


Ground water and rainfall could eventually fill up a quarry. Removing this water is a continuous process at Mundy Quarries. We use a portion of this water through sprays and water trucks to control dust. Some of the water is blended into dense-graded base mixes to insure optimum moisture for compaction. The remainder of the water is released into nearby streams. This water has a positive impact on the environment because it augments stream flow during dry periods and the superfine limestone dust in the water neutralizes and counteracts the effects of acid rain and acidic fertilizer runoff. 

In the act of mechanically crushing rock by brute force, a great deal of dust is produced. Although the rock dust is safe, it is a nuisance from the standpoint of visibility and, therefore, is considered an air pollutant. Both locations utilize "latest available technology" to capture and control over 95% of the dust produced by the stone crushing operations. Control measures include the use of dust collectors (huge vacuum cleaners), and water spray on the crushers. Water trucks eliminate dust from haul roads and stone stockpiles. Delivery dump trucks pass under a water spray bar that dampens the crushed stone prior to delivery. This helps insure that there won't be any objectionable dust when Mundy crushed stone is used at your home or job site. 

The Virginia Department of Environmental Quality (DEQ) regulates air and water emissions by issuing permits that detail approved methods and required results of Mundy pollution abatement efforts. Mundy Quarries also contracts with an independent testing laboratory to monitor dust emissions and discharge water quality.
