It has been quite a success story for White Rock Quarries. The Miami-Dade limestone quarry began operation in 1987 with an emphasis on high-volume production, strict quality control and unsurpassed customer service.
The formula has worked so well the quarry’s road to success has been steep, but not too rocky.
In just 15 years White Rock has grown to become the fourth largest crushed stone operation in the United States, according to the U.S. Geological Survey.
The quarry provides customers with a wide variety of DOT-certified crushed aggregates and screenings for use in cement, concrete, concrete products, road construction and asphalt pavement. The products are moved by truck and rail to valued customers throughout Florida.
Despite its large-scale operations, White Rock maintains the friendly feel of a smaller quarry, providing personalized attention for each customers’ needs and making sure every truck is loaded quickly and ticketed correctly.
Every aspect of the operation is run at peak efficiency. Even the blasting technology is the most advanced available, fragmenting the limestone for processing at the lowest possible vibration levels – well below established limits.
Growth Increases
Employees’ Opportunities
As White Rock has grown, so have the opportunities for its employees. Most of its supervisors and foremen started at “ground level” and worked their way up.
Just one example is Hector Barrios, night shift production foreman. Barrios started as a laborer in 1993, moved on to plant operator, was promoted to lead foreman, then was made a foreman.
There are “success stories” such as this throughout White Rock, where loyalty and hard work are always appreciated. In fact, Barrios’ father, Pedro Barrios, was hired in 1986 as White Rock’s first truck driver. He liked the job so much, he has never left.
“We treat everyone as we want to be treated,” said White Rock’s Vice President Raymond Maddy, who began as a quarry operator in West Virginia before rising to foreman and joining White Rock in 1986.
White Rock might be considered young by business standards, but on this is certain: Its formula for success – high volume, top quality and great service – has proven rock solid.
