Hamm, Inc.

What Hamm, Inc. does

Hamm, Inc., operating as HAMM Companies, is a privately held construction materials supplier headquartered at 609 Perry Pl, Perry, Kansas. Founded in 1954, the company has built a 70-plus year operating history focused on the Midwest U.S. market. The firm employs over 500 people across its operations and is described in its own materials as a Midwest leader in aggregates and ready-mix concrete.

The company offers four core lines: Aggregates (crushed stone, sand, gravel) for infrastructure and building projects; Ready-Mix concrete delivered to construction sites for foundations, structures, and paving; Excavation services for site preparation; and Waste Services for construction and demolition material disposal. The core technology is conventional — quarrying, batching, and delivery of heavy construction commodities — with no proprietary software, digital platform, or AI/ML capabilities disclosed.

HAMM generates revenue through one-time sales of aggregates and project-based sales of ready-mix concrete, supplemented by excavation and waste service contracts. Pricing is quote-based and not publicly disclosed; customers must contact the company directly. The go-to-market is sales-led and relationship-driven, targeting general contractors, commercial builders, and infrastructure developers across the Midwest via direct sales, on-site delivery, and a quote-request funnel on its website. The company is privately held with no disclosed institutional investors, funding rounds, or parent entities.

Broad incumbents

• Granite Construction Incorporated: Vertically integrated heavy civil contractor and aggregates producer operating across the western and central US. Comparable to HAMM in aggregates production and infrastructure project exposure, but with a heavier construction-services tilt.
• Vulcan Materials Company: The largest US producer of construction aggregates with a national footprint. Direct product overlap with HAMM in crushed stone, sand, and gravel, and operates ready-mix concrete through legacy U.S. Concrete assets.
• CEMEX, S.A.B. de C.V. Global cement, aggregates, and ready-mix producer with a significant US footprint. Comparable to HAMM as a vertically integrated building materials supplier, though at global scale and with a heavier cement tilt.
• CRH plc: Global building materials giant with extensive US aggregates and ready-mix operations (including recent Summit Materials acquisition). Overlaps with HAMM across aggregates and ready-mix categories at much larger scale.
• Martin Marietta Materials: One of the two largest US aggregates-led building materials companies with nationwide operations. Operates the same aggregates-heavy business model as HAMM but at vastly greater scale and geographic reach.
• LafargeHolcim: Global leader in aggregates, cement, and ready-mix with a meaningful US presence. Comparable to HAMM as a vertically integrated construction materials platform, though with global operational and capital scale.
