What White Rock Quarries does

White Rock Quarries is a privately held Florida limestone quarrying operation and a division of Vecellio & Grogan, itself part of the family-owned Vecellio Group. Founded in 1986, the company operates the main quarry along US-27/Okeechobee Road in western Miami-Dade County and a South quarry a few miles away near Doral, producing DOT-certified crushed limestone aggregates, fine screenings, and limerock road base. It claims recognition as the largest-producing single-site crushed stone quarry in the United States, anchored by a Marion 8200 walking dragline with a 105-cubic-yard bucket capable of yielding up to 24 million tons per year, and ranks among the Top 25 U.S. aggregates companies per Aggregates Manager.

The operation runs a continuous-cycle mining, processing, and loadout workflow using the dragline, high-capacity CAT off-highway rear-dump trucks, two processing plants, and six outbound scales with remote ticket printers. Distribution is delivered directly via company truck fleet and via rail through proximity to the Florida East Coast Railroad, with rail reach from Miami to Jacksonville along Florida's east coast. A mobile crushing unit recycles thousands of tons of old roadway material per year. The WRQ NOW customer portal provides customers with real-time account activity, one-click truck dispatch, job and shipment tracking, and on-demand reporting across iPhone, Android, and Windows.

Revenue is generated through per-transaction, weight-based sales of bulk aggregates and screenings to road construction companies, asphalt pavement producers, ready-mix concrete producers, concrete products manufacturers, and government buyers led by the Florida Department of Transportation. Pricing is negotiated and not publicly disclosed. The company is fully owned by Vecellio & Grogan with no external investors, public listing, or disclosed funding rounds.

Direct peers

• Martin Marietta Materials: Second-largest U.S. aggregates producer with significant Florida and Gulf Coast crushed stone operations. Directly comparable as a vertically integrated aggregates supplier serving DOT, ready-mix, and asphalt customers in the southeastern U.S.
• Arcosa, Inc. Diversified infrastructure products company with a sizable construction aggregates segment across the southern U.S. Comparable as a regional aggregates producer serving DOT and heavy-civil customers.
• Cemex USA: Major Florida aggregates producer (legacy Rinker Materials), supplying crushed stone, ready-mix, and concrete products statewide. Competes head-to-head with White Rock for Florida DOT, asphalt, and ready-mix customers.
• Vulcan Materials Company: Largest U.S. producer of construction aggregates, including crushed stone, with major Florida operations (legacy Florida Rock Industries). Closest direct competitor to White Rock in Florida crushed limestone, sharing the same DOT-approved customer base and end markets.
• Summit Materials: Vertically integrated aggregates and cement producer with operations across the U.S., including the Southeast. Competes with White Rock as a multi-product aggregates supplier serving infrastructure and construction end markets.
• Bluegrass Materials: Southeast-focused aggregates producer supplying crushed stone to infrastructure and construction customers. Comparable as a regional crushed stone peer with overlapping customer types in road and concrete end markets.

Regional players

• Dolese Bros. Co. Privately held Oklahoma-based crushed stone, sand & gravel, and ready-mix producer. Comparable operating model as a privately held regional aggregates company, though not a direct Florida competitor.
• Luck Companies: Privately held Mid-Atlantic crushed stone and aggregates producer (Virginia, Carolinas). Comparable as a privately held, regionally focused crushed stone operator serving DOT and construction customers.

Broad incumbents

• US Lime & Minerals: Largest U.S. lime producer, also operating limestone quarries across multiple states. Comparable as a publicly listed limestone mining operator, though focused on higher-value lime rather than construction-grade aggregates.

Others

• Vecellio & Grogan: Parent division and sister construction firm of White Rock Quarries within the Vecellio Group. Adjacent rather than directly competitive, but acts as a captive customer for aggregates on Florida road and bridge projects.
