Central Stone

What Central Stone does

Central Stone Company is a privately held construction aggregates producer operating 25+ quarry and plant locations across Western Illinois and Eastern Missouri. Incorporated in 1949 and tracing its operational roots to the Missouri Gravel Company founded in 1925, the company mines, crushes, washes, and distributes limestone, granite, trap rock, sand, river gravel, agricultural lime, rip rap, boulders, ball diamond aggregate, ice control chips, and recycled asphalt and concrete. Its customers span construction contractors and ready-mix/asphalt producers (primary), homeowners and landscapers, the agricultural sector (ag lime for soil pH management), the railroad industry (ballast), and sports/recreation facilities (drainage aggregate). Materials are sold via quote-based direct sales organized by product line (Granite/Trap Rock, Limestone, Sand & Gravel) and delivered by truck, barge (Mississippi River), or rail car.

The company's core technology is a proprietary, highly automated dynamic process control system that monitors thousands of data points per second at each plant, automatically adjusts operating parameters, and can trigger emergency shutdowns without human intervention to protect personnel and equipment. An in-house electrical engineering team continuously improves these controls, and the company emphasizes a self-sufficiency operating philosophy supported by certified engineers, geologists, welders, and experienced operations staff. The company also operates a website-based Materials Calculator for project estimation and publishes safety data sheets, gradations, and product technical resources for engineering customers.

Central Stone generates revenue through one-time aggregate material sales with quote-based, pay-as-you-go billing and no publicly disclosed pricing. Distribution is direct, primarily through pickup at quarry sites and direct delivery to construction job sites, with no apparent reseller or third-party logistics intermediaries. Pricing is determined by dedicated sales representatives per product line, and the company advertises a multi-modal logistics capability (truck, barge, rail) as a competitive lever for large projects. The company has no disclosed parent company, no institutional investors, no funding rounds, and no listed leadership team in the source material, though one operational contact uses a Riverstone Group email domain, suggesting a possible but unconfirmed operational relationship.

Products and services

• Aggregate Base Crushed limestone aggregate used for road base and stabilization underneath roadways; supplied to construction companies and contractors.
• Agricultural Lime Crushed limestone fines used by farmers and agricultural operations to neutralize soil pH and improve crop nutrient absorption, yields, and soil structure.
• Asphalt & Concrete Stone Washed crushed limestone used in Ready Mix Concrete and Asphalt paving, also for seal coat applications, pipe bedding, and foundation drainage.
• Manufactured Sand Finely graded, washed limestone product used in Ready Mix Concrete and Asphalt paving, with higher angularity than natural sand.
• Rip Rap & Erosion Stone Erosion control stone for shorelines and sloped areas, available in sizes from 6 inches (50 lbs) to 22 inches (1000 lbs) or greater, with Army Corps of Engineers certified options available.
• Natural Sand High quality washed sand dredged from old river deposits, primarily used in Ready Mix Concrete and Asphalt, also for seal coat applications, precast block, and retaining wall backfill.
• River Gravel Natural river gravel used for decorative landscaping, construction, and design projects, chosen for its appearance and lack of sharp edges.
• Black Diabase Extremely hard igneous rock (also called black granite) with crystalline structure, used in construction and landscape design due to its dark coloration.
• Gray Granite Granite used primarily in road building or as decorative landscaping material, available as aggregate base or washed asphalt/concrete stone.
• Railroad Ballast Durable crushed granite or trap rock forming a track bed between, below, and around railroad sleepers, providing strength, support, and flexibility.
• Red Granite Decorative red-colored granite used for landscaping and construction applications.
• Trap Rock Dark-colored igneous rock similar to granite but more closely related to basalt, used in construction and landscaping applications.
• Boulders Boulders available in various shapes, sizes, and colors including limestone and trap rock, used for finishing touches on commercial or residential projects.
• Trap Rock Boulders Boulders made from trap rock used as decorative and finishing landscape elements on commercial and residential projects.
• Ball Diamond Aggregate Finely crushed and washed limestone that allows water to pass through, preventing rain delays on baseball and softball fields.
• Ice Control Chips Washed chips providing traction on slippery roads during winter months as an alternative to salt, without corrosion to vehicles.
• Recycled Asphalt & Concrete Crushed asphalt for driveways or parking lot surfacing; crushed concrete for compactable sub base material under commercial paving projects.
• Materials Calculator Online tool that estimates materials needed for projects, calculating estimated tons and cubic yards based on area shape, dimensions, and selected material type; intended for construction companies, contractors, homeowners, and landscapers.

Broad incumbents

• Martin Marietta Materials: Top-tier U.S. aggregates producer with operations across the country, including heavy reliance on limestone and granite quarries. Highly comparable product mix and customer base, though far larger and publicly traded, and serves as a key benchmark for regional aggregates pricing.
• CRH plc: Global building materials giant with extensive aggregates operations across North America through subsidiaries like Oldcastle. Competes in the same construction aggregates market segments and offers the same limestone, granite, and sand & gravel product categories.
• Vulcan Materials Company: Largest U.S. producer of construction aggregates with nationwide footprint and vertically integrated operations. Comparable as the national benchmark for aggregates pricing, scale economics, and reserve management; competes in some of Central Stone's downstream construction end markets.
• Holcim (Aggregate Industries): Global building materials major with significant U.S. aggregates operations through its Aggregate Industries subsidiary. Comparable in product breadth and end-market exposure, particularly for ready-mix concrete and asphalt aggregates in the Midwest.
• Summit Materials: Vertically integrated construction materials producer with significant aggregates operations in the Midwest and Western U.S. Comparable as a multi-product aggregates, cement, and ready-mix player serving similar end markets to Central Stone.

Direct peers

• New Enterprise Stone & Lime Co. Private Pennsylvania-based aggregates producer with limestone quarries, asphalt plants, and ready-mix operations across the Mid-Atlantic and Midwest. Closely comparable as a privately held, multi-generation aggregates company with similar horizontal product portfolio and direct-to-contractor sales model.
• Rogers Group: Privately held aggregates and construction materials company operating quarries across the Midwest and South. Directly comparable as a privately held, multi-quarry aggregates producer with similar product mix of crushed limestone, sand, and gravel serving construction customers.
• Riverstone Group: Midwest-based aggregates producer with operational ties to Central Stone (Carthage Quarry contact uses a riverstonegroup.com email and careers site hosts on Riverstone's platform). Directly comparable in limestone and sand & gravel quarrying across overlapping Midwestern geographies.

Regional players

• Capital Sand Company: Missouri-based sand and aggregates supplier serving construction and industrial customers in the central U.S. Directly overlaps with Central Stone's geographic footprint in Missouri and competes in the same sand and gravel product categories.
• Pattison Sand Company: Iowa-based specialty sand producer focused on industrial and construction sands. Comparable as a Midwest regional aggregates player with sand-focused product portfolio, though primarily serving different downstream end uses.
