A. After breaking the rock from the working face, a truck or conveyer hauls the rock to a crusher; which produces an assortment of final sizes to meet customers’ needs.
Throughout the extraction process, we use the most advanced technology available and conduct thorough monitoring with highly sophisticated seismic instruments. In fact, Miami-Dade County’s blasting limits are 62 percent tougher than the guidelines established by the U. S. Bureau of Mines—and we continue to operate well within those tough local limits.
A. Crushed limestone is an essential ingredient in concrete asphalt and cement – the products we take for granted to build our homes, schools, hospitals, offices and the roads we travel daily.
A. When it comes to protecting the environment, we’re proud to be part of the solution. With concerns about protecting the Everglades from urban sprawl continuing to grow, regulators and environmentalists have recognized limestone operations as a natural buffer. Moreover, the U.S. Army Corps of Engineers and the South Florida Water Management District’s Everglades Restoration Plan includes Miami-Dade limestone quarries as a vital water storage area.
A. People often use “concrete” and “cement” interchangeably, but did you know they’re completely different products?
Cement is a binder. It sets and hardens to bind other materials together and is the main ingredient in ready-mix concrete: a mixture of cement, aggregates, water and admixtures. Cement is made using a process called calcination—where limestone is heated with other materials to 1450 degrees Celsius, resulting in a hard substance called clinker. The clinker is then ground into a fine powder to make cement.
A. Since 1999, the limestone products industry has contributed over $126 million to protect, preserve and restore the Florida Everglades. It’s part of the historic Lake Belt Plan—developed by a group of civic, business and environmental leaders—which established a long-term approach to permitting that secures jobs, provides operating certainty, and protects the environment.
