White Rock Quarries – Spring 2007 Doral Relay For Life – Slide Show August 25, 2007October 11, 2021 Click an image to begin the slide show. Why are limestone aggregates so important to the state of Florida? Let’s take a look!White Rock Quarries is proud to support the Doral Relay For Life.We are also proud to operate one of the Top 2 quarries in the U.S.White Rock’s operations help meet Florida’s huge demand for limestone aggregates.White Rock’s main Miami location has two processing plants and six outbound scales.We use a 105-cubic-yard dragline to efficiently recover fragmented limestone for processing.Here is a view from the control room during the Grand Showing tour of the dragline.We use a 105-cubic-yard dragline to efficiently recover fragmented limestone for processing.High-capacity loaders bring the recovered limestone to a portable road rock crusher.The road rock crusher produces state-certified base rock for road construction.Limestone is also processed through the plants, creating various smaller sizes of state-certified aggregates, as well.Customers’ orders are filled quickly and efficiently using high-capacity loaders.We also ship aggregates by rail throughout the state of Florida.Extensive lab testing and monitoring of all operations ensures strict quality control.We also operate White Rock South, a few miles from the main location.White Rock South operates on the same high-quality production principles.At both locations, White Rock provides fast, efficient service to help meet the demand for limestone.White Rock also operates a mobile unit recycling thousands of tons of old roadway materials each year.Limestone is vital for transportation. It is used for road foundations, asphalt pavement, concrete bridges, even airport runways.Limestone provides a stable base material for road construction.Limestone aggregates can be spread and compacted, then topped with asphalt pavement.Asphalt pavement is made from limestone aggregates mixed with asphaltic cement.Asphalt pavement is vital for commercial, residential and transportation construction.Asphalt is just one of many products made using limestone aggregates.Limestone is also used to make bridge piers, bridge decks and other concrete products.You benefit from limestone aggregates virtually every time you cross a concrete bridge in Florida.R.E. (Reinforced Earth) walls are another limestone-containing product.Concrete pipes, made using limestone materials, are vital for drainage in Florida.Concrete pipes are manufactured in a wide range of sizes using limestone materials.Pre-cast concrete structures, such as this culvert, are also made using limestone.Limestone is also used in concrete blocks, literally the “building blocks” of the construction industry.Concrete block construction is a common sight throughout Florida.“Ready-mix” concrete is another common construction material made using limestone.Ready-mix concrete is poured or pumped into specially-shaped forms.Ready-mix concrete is also poured into forms for “tilt-up wall” construction.Limestone is also used in making paver bricks, roof tiles, statues, fountains and more.White Rock is helping build a sustainable Florida with our vital limestone products!
