White Rock has cemented its reputation as a high-volume, low-cost producer of limestone aggregates. Its main quarry, situated along US-27 / Okeechobee Rd. in Miami-Dade County, FL, has been recognized as the largest-producing crushed stone location in the United States.

Serving Florida’s commercial aggregate needs since 1986, White Rock has grown in both size and capacity over the years. It recently upgraded to the world’s largest aggregate dragline, a Marion 8200 with a 105 cu. yd. bucket, capable of yielding 24 million tons per year.

White Rock also operates a South quarry a few miles away near the city of Doral.

Together, the two locations put White Rock among the Top 25 aggregates companies in the U.S., according to Aggregates Manager magazine, citing U.S. Geological Survey data.
