Hawaiian Cement

What Hawaiian Cement does

Hawaiian Cement is a vertically integrated construction materials supplier operating exclusively in the State of Hawaii, producing and distributing cement, construction aggregates, and ready-mix concrete for residential, commercial, and public infrastructure projects. The company traces its quarrying operations to 1939 (Halawa Valley Quarry) and its formal incorporation as Hawaiian Cement Co. to 1959, with the first cement plant opening on Oahu in August 1960. Today it operates through three primary divisions—Cement, Oahu Concrete and Aggregate, and Maui Concrete and Aggregate—supplemented by the West Hawaii Concrete subsidiary on the Big Island. Distribution is handled through owned cement terminals at Hilo, Kahului, Lihue, Kalaeloa Barbers Point, and Kawaihae harbors, plus ready-mix dispatch operations on Oahu and Maui.

The company sells four core product streams—bulk and bagged cement, aggregate products (Halawa and Maui), ready-mix concrete, and specialty items (colored concrete, silica sand, Class F fly-ash, bagged masonry cement, golf course sand, and decorative stone). Underlying technology centers on conventional construction materials production: cement import and terminal handling, aggregate quarrying and crushing, and ready-mix concrete batching and dispatch. Supporting digital tools include a Concrete and Aggregate Volume Calculator on the website and a Mastercolor Selector for colored concrete, but there is no software platform or proprietary AI/ML capability.

Hawaiian Cement's business model is sales-led B2B with revenue generated through one-time purchase orders (cement, aggregate, ready-mix, specialty products) at volume-based pricing with disclosed discounts available on direct contact. Customers are segmented across residential builders, commercial developers/contractors, and government/public works agencies, served via direct contact, phone dispatch, and field sales representatives across the Hawaiian islands. The company is a wholly-owned subsidiary of Knife River Corporation, a North Dakota-based aggregates company, following an acquisition around 1999 that also marked the transition from local cement manufacturing to bulk cement importation. Headcount is approximately 200 employees and revenue is not publicly disclosed.

Scale indicators3 records

Recent moves9 records

Expansion highlights4 records

Broad incumbents

• CEMEX: Global building materials company producing cement, ready-mix concrete, and aggregates with substantial U.S. operations through Cemex USA. Same core product mix, end-markets, and commodity-style operating model.
• Vulcan Materials Company: Largest U.S. producer of construction aggregates with adjacent ready-mix concrete operations. Comparable business model (aggregates-led, vertically integrated), similar end-markets, and similar exposure to U.S. construction cycles, though operating at much greater continental scale.
• Martin Marietta Materials: Major U.S. supplier of aggregates (crushed stone, sand, gravel) and ready-mixed concrete. Comparable product portfolio and end-market exposure, with similar reliance on public infrastructure and private nonresidential construction demand.
• Knife River Corporation: Direct parent company and largest U.S. aggregates and ready-mix operator across multiple states. Comparable because it is the same business model (vertically integrated construction materials), same corporate family, and similar end-markets; Hawaiian Cement is essentially a Knife River regional division.
• Summit Materials: U.S. vertically integrated construction materials company with operations in cement, aggregates, and ready-mix concrete. Similar business model and end-market exposure to Hawaiian Cement, though focused on continental U.S. markets.
• Heidelberg Materials (formerly Lehigh Hanson): One of the world's largest cement, aggregate, and ready-mix concrete producers with significant U.S. operations. Closely comparable because it operates across the same three product categories (cement, aggregate, ready-mix) and serves the same end-markets, but at vastly greater scale.

Emerging players

• Quikrete Holdings: Large U.S. producer of packaged concrete, cement mixes, and related specialty construction products including bagged masonry cement (overlapping Hawaiian Cement's bagged masonry cement offering). Comparable on specialty/add-on product lines but lacks ready-mix distribution depth.

Regional players

• Grace Pacific Corporation: Hawaii-based construction materials and paving company producing aggregates and ready-mix concrete on Oahu and other islands. Overlaps with Hawaiian Cement in aggregate supply and asphalt/paving-related concrete; competes for the same state and county infrastructure contracts.

Direct peers

• HC&D (Hawaii Concrete & Aggregates): Hawaii's other major ready-mix concrete and aggregate producer, headquartered on Oahu. Directly competes in the same island markets with similar product offerings, making it the closest head-to-head competitor for Hawaiian Cement's core ready-mix and aggregate lines.
