What Ozinga does

Ozinga Bros., Inc. is a fifth-generation, family-owned construction materials company founded in 1928 and headquartered in Mokena, Illinois, that supplies ready-mix concrete, specialty concrete, aggregates, cement, slag, supplementary cementitious materials (SCMs), and related bulk materials across the Midwest and South Florida. Its core offering is ready-mix concrete delivered via a branded fleet of red-and-white mixer trucks, supported by 70+ company-operated locations, 200+ additional source locations, and a multi-modal logistics network spanning truck, rail, barge, and ship terminals. Specialty product lines include Fiber Reinforced Concrete, OzFlat Series (with proprietary OzingaShield integral sealer), Aridus rapid-drying concrete, Filtercrete pervious concrete, high-strength, high-early, jointless, lightweight, roller-compacted, and self-consolidating mixes. Sustainability-positioned products center on CarbonCure CO2-sequestration injection, the tiered CarbonSense low-embodied-carbon line (achieving 18-68% GWP reductions versus NRMCA benchmarks), High-Albedo reflective concrete, and SCMs delivering up to 70% recycled cementitious content.

The company monetizes primarily through per-delivery, transaction-priced sales under COD terms across regional dispatch centers in Illinois, Indiana, Wisconsin, Michigan, and South Florida, with additional revenue from bulk materials, on-site volumetric mixing, mobile concrete plants, parking-lot design services, and the CarbonSense Lab. Its go-to-market is sales-led, anchored by named-account relationships with general contractors (e.g., Walsh Construction, Superior Construction, Related Midwest), architects (Studio Gang), and institutional customers (McDonald's flagship renovation, Meta Data Center), supplemented by a direct-to-homeowner channel through the Ozinga Home platform and a CNG/renewable-natural-gas station business via subsidiary Ozinga Energy. The business is privately held by the Ozinga family, with no institutional investor disclosed; notable forward signals include a serial acquisition cadence (Barreiro 2022, RMB 2024, Elston volumetric assets 2025), pursuit of a $50 million rival deal (contested in family litigation filed February 2026), and a capital project (grinding mill) whose budget has overrun from $65 million to over $150 million.

Partnerships

Seven partnerships are on record, tiered core and minor.

• CarbonCure TechnologiescoreTechnology or IntegrationCarbonCure Technology partnership enables injection of recycled CO2 (sourced from United Ethanol plant in Wisconsin) into Ozinga's concrete at the batching plant. The CO2 chemically converts into calcium carbonate mineral permanently embedded in the concrete, improving compressive strength and reducing carbon footprint by ~25 lbs CO2/cubic yard. Originally available at select Chicagoland yards, now available at all Ozinga ready mix plants. Bill Gates invested in CarbonCure and highlighted it on 60 Minutes as an innovation to fight climate change.
• Elston MaterialscoreStrategic or Co-development PartnerOzinga acquired the volumetric concrete assets of Elston Materials in Chicago. The acquisition expands Ozinga's on-demand concrete mixing capabilities, particularly for small and mid-size pours, repair/maintenance work, utility projects, and hard-to-access locations. Volumetric mixing produces concrete at the job site with real-time mix design adjustment.
• RMB ConcreteminorStrategic or Co-development PartnerOzinga acquired the assets of RMB Concrete of Riviera Beach, FL in 2024. RMB had operated in Riviera Beach since 1971. The acquisition expanded Ozinga's ready-mix operations in South Florida.
