Lhoist North America

What Lhoist North America does

Lhoist North America is the U.S. operating subsidiary of Lhoist Group (S.A., Belgium), a privately held, family-owned producer of lime, dolime, and process minerals founded in 1889. Headquartered in Fort Worth, Texas, the business operates 20 quarries and production facilities and 45 distribution terminals in the United States, with reported control of over 2 billion tons of limestone reserves concentrated in Sun Belt metropolitan corridors. For FY2025, Lhoist North America generated $1.8 billion in gross sales and $786 million in adjusted EBITDA, representing a portion of Lhoist Group's global operations, which span 130+ sites across 20+ countries and 6,400+ employees with sales reach into 80+ countries.

The company's core product portfolio comprises quicklime (calcium oxide), hydrated lime, milk of lime, dolime, limestone, dolomite, clay, aggregates, custom mineral blends, and specialty products, marketed through established sub-brands including Akdolit (water filtration), Sorbacal (flue gas treatment), Calexor (metallurgy), Hypel (steelmaking), Tradical (building materials), Proviacal (soil stabilization), Asphacal (asphalt), Emgesal/Oxyfertil (agriculture), Visucal (glass), and Neutralac/Neutracal (water treatment). Underlying manufacturing relies on calcination technology — primarily rotary kilns and parallel-flow regenerative vertical shaft furnaces (PFRK) — protected by a portfolio of nearly 600 granted or pending patents and supported by two global R&D centers. The Customer Technical Services team delivers on-site trials, pilot testing, audits, and process optimization as an embedded service layer.

Revenue mechanics are entirely B2B and industrial: pricing is quote-based and undisclosed; the go-to-market combines direct enterprise sales with a technical-advisory overlay for large accounts in steel, water treatment, roads and civil engineering, building materials, agriculture, glass, pulp and paper, non-ferrous metallurgical processing, chemicals, and flue gas treatment. Distribution is multimodal (rail, road, river, short-sea, deep-sea) via the company-owned site and terminal network. Sales mix is diversified, with steel identified as the largest single end-market and other segments contributing the balance.

Recent moves5 records

Expansion highlights5 records

Direct peers

• Carmeuse: Carmeuse is a privately held, family-owned global producer of lime, dolime, and limestone with operations across Europe, North America, and Africa — Lhoist's closest direct rival across virtually every product line and customer segment the company serves. Both companies were founded in the 19th century and remain family-controlled.
• Graymont: Graymont is a privately held Canadian-headquartered lime and dolime producer with significant operations in the U.S., Canada, and Asia-Pacific. It directly competes with Lhoist North America across steel flux, water treatment, construction, and chemical lime, with comparable vertically integrated quarry-to-terminal models.
• Mississippi Lime Company: Mississippi Lime is one of the largest U.S. producers of high-calcium quicklime and hydrated lime, serving steel, water treatment, construction, and chemical customers. It is a direct North American competitor with overlapping product portfolio and customer base to Lhoist's core lime operations.
• US Lime & Minerals: US Lime & Minerals is a U.S. lime producer focused on Texas, Oklahoma, and Arkansas, now controlled by Grupo Calidra. It directly competes with Lhoist North America in high-calcium lime for steel, construction, and chemical applications, although at a smaller scale.

Regional players

• Nordkalk: Nordkalk is a leading European producer of limestone-based products including quicklime, hydrated lime, and ground calcium carbonate, owned by Finnish Rettig Group. It competes with Lhoist in steel, paper, and environmental applications but primarily serves Northern Europe rather than North America.

Broad incumbents

• Imerys: Imerys is a publicly traded French multinational that produces mineral-based specialty solutions for industry, including calcium carbonates, and competes with Lhoist in certain fillers, paper, and construction applications. It is broader than Lhoist, but its Performance Minerals and Solutions segments overlap with several of Lhoist's mineral product lines.
• Martin Marietta Materials: Martin Marietta is the announced acquirer of Lhoist North America and a leading U.S. producer of aggregates, cement, and ready-mixed concrete. Post-closing it will inherit Lhoist's lime footprint, and historically it has competed with Lhoist in aggregates and road construction soil stabilization segments.
• CRH plc: CRH is a publicly traded Irish-headquartered building materials conglomerate with North American aggregates, cement, and lime operations. It competes with Lhoist in road construction, building materials, and aggregates distribution across multiple U.S. markets.

Emerging players

• Minerals Technologies Inc. MTI is a publicly traded U.S. specialty minerals company whose Paper PCC business uses precipitated calcium carbonate — a partial substitute/adjacent product for Lhoist's lime-based pulp and paper applications. It represents an emerging competitive force in value-added downstream applications rather than commodity lime.

Others

• RHI Magnesita: RHI Magnesita is the world's largest refractory supplier serving steel, cement, and glass industries. While Lhoist sells refractory maintenance products (Doloram/Dolofrit) for steelmaking vessels, RHI Magnesita is a customer-adjacent supplier of complementary refractory linings rather than a direct lime competitor.
