What Dolomite Group does

Dolomite Group, Inc. is a privately held regional construction materials supplier headquartered in Rochester, NY and operating as a subsidiary of the global building materials conglomerate CRH. Founded in 1920 by John H. Odenbach, the company produces and sells three core product lines — aggregates (crushed stone, sand, gravel, and recycled materials), hot-mix and cold-mix asphalt, and ready-mix concrete — through retained wholly-owned sub-brands including Rochester Asphalt Materials (RAM), Manitou Concrete, Northrup Materials, Iroquois Rock Products, and the Southern Tier operating DBA A.L. Blades.

The business operates ten-plus active production, quarry, and administrative sites across the Greater Rochester Area and the Southern Tier of Upstate New York, including locations in Rochester, Brockport, Farmington, Newark, Henrietta, Penfield, Manchester, and Walworth. Its concrete operations are supported by an integrated computer-based batching, dispatch, and job-tracking system that the company describes as nationally recognized and is deployed uniformly across the Manitou and Northrup plant networks. Depleted quarry sites have been redeveloped into the Shadow Lake Golf Course and Allens Creek Valley Townhomes, indicating long-term land stewardship and post-extraction reuse practices.

Revenue is generated on a project-by-project basis through direct sales to infrastructure (highways, roads, airports), commercial, and residential construction customers, with both commercial and residential delivery services. Pricing is not publicly disclosed; quotes are handled through a regional sales team of roughly nine named representatives organized by geography (Greater Rochester, Finger Lakes, Southern Tier) and product line. With 51–100 employees and no external funding rounds, Dolomite functions as a mid-sized, regionally anchored operating unit within CRH's broader North American footprint rather than an independent growth-stage enterprise.

Core offering

Dolomite Group produces and supplies construction materials including aggregates (crushed stone, sand, gravel, and recycle materials), hot-mix and cold-mix asphalt, and ready-mix concrete from owned quarries, sand pits, and production facilities across Upstate New York. Products are delivered directly to commercial, infrastructure, and residential construction job sites via the company's own fleet, supported by regional sales representatives and integrated batching and dispatch systems.

Product overview

Dolomite Group is a construction materials supplier offering a portfolio of three core product lines under distinct sub-brands. The company provides aggregate materials (crushed stone, sand, gravel, and recycle materials) directly, asphalt products through Rochester Asphalt Materials (RAM) and Iroquois Rock Products, and ready-mix concrete through Manitou Concrete and Northrup Materials. All product lines are supported by residential and commercial delivery services, with facilities strategically positioned throughout the Greater Rochester Area and Southern Tier of New York. The company operates integrated computer batching and dispatch systems for concrete operations, but does not offer a unified software platform—instead providing discrete construction material products with associated delivery logistics.

Broad incumbents

• Summit Materials: A vertically integrated construction materials producer of aggregates, cement, ready-mix concrete, and asphalt across North America. Closest publicly listed peer to Dolomite's product mix and regional operating model.
• U.S. Concrete / Vulcan Materials (NY operations): U.S. Concrete (acquired by Vulcan in 2021) operated a major NY/NJ aggregates and ready-mix network and now forms part of Vulcan's Northeast footprint. Provides a direct competitor against Dolomite in NY metropolitan-adjacent infrastructure work.
• Heidelberg Materials (Lehigh Hanson): One of the world's largest building materials companies producing aggregates, ready-mix concrete, cement, and asphalt. Relevant global benchmark and potential indirect competitor in NY-area infrastructure tenders.
• Martin Marietta Materials: A publicly traded US producer of aggregates, cement, ready-mixed concrete, and asphalt. Provides scale benchmark on cost structure, pricing, and capital allocation relevant to Dolomite's vertically integrated regional model.
• Vulcan Materials Company: The largest US producer of construction aggregates, also operating in asphalt and concrete. Operates at national scale versus Dolomite's regional scope but competes for the same end customers in NY-adjacent and national-contract bids.

Direct peers

• Tilcon New York: A CRH subsidiary operating in New York and Connecticut producing aggregates, hot-mix asphalt, and ready-mix concrete. Direct comparison to Dolomite given shared parent, shared geography (NY), and nearly identical product portfolio of aggregates, asphalt, and concrete.
• Callanan Industries: A CRH subsidiary supplying aggregates, asphalt, ready-mix concrete, and construction services across Upstate and Downstate New York. Almost identical business model and customer base to Dolomite as a fellow CRH-owned regional materials platform.
• Peckham Industries: A privately held, family-owned producer of road construction materials including aggregates, asphalt, and emulsions across the Northeast US, headquartered in New York. Closest independent regional competitor in scope and geography.

Others

• Lane Construction (CRH subsidiary): A heavy civil construction contractor and CRH subsidiary that both sources and competes for infrastructure work Dolomite serves. Sister CRH entity with strong adjacency in aggregates supply for major highway and airport projects.

Emerging players

• Arcosa, Inc. A diversified manufacturer of infrastructure products including natural and recycled aggregates, with a growing construction materials segment. Useful emerging comp for recycled-aggregate expansion strategy at Dolomite.
