Limestone Aggregate – Our limestone aggregate is recycled fossil stone mined in South Central Florida.  Screened and washed, the material is used for many applications.  Transcor continually innovates in order to minimize the use of virgin aggregate resources.  Alternative secondary materials, such as by-products of other manufacturing processes and recycled materials, are incorporated into a number of the construction products in our range to create sustainable products.

Our limestone is a recovered material that is double washed and screened to size – yes, it is considered recycled.  All three sizes of material produced can be considered for LEED CREDIT.  We size the limestone to meet a #89 (3/8” minus) and #57 (1 1/2” minus) course aggregate specification.  Our ballast is a 2”- 4” limestone that is used for ditch lining, temporary driveways, and landscaping.  Custom sized material can be manufactured, with advance notice, to meet your job needs.

Material History

It is very common to find sharks teeth and other petrified fossils in the limestone products due to the fact that sixteen million years ago, thick forests and grassy plains covered a short, wide peninsula that only went as far south as what is now Polk County.  At that time, 6-foot tortoises, shovel-tusked mastodons, hornless rhinos, humpless camels, iguanas, Gila monsters, and 30-foot crocodiles roamed the area.  The surrounding warm waters were filled with a rich variety of life, as well, including long-beaked dolphins, bony fish, rays, sea cows, and sharks, including the notorious (and now extinct) giant, killer shark – megladon.  Fossils such as the teeth of giant sharks and the bones of huge whales can be seen throughout central Florida.

Fossils found in Bone Valley include many species that came to tropical and subtropical frost-free Florida forests to escape the advancing glaciers of the great “Ice Ages”.  Some of these animals migrated to North America from other parts of the world; for example, some of these animals came across the Bering Strait land bridge from Asia when seal level was lower.  Others traveled around the rim of the Gulf of Mexico, when areas that are now submerged were exposed.  Dinosaur fossils associated with the Florida phosphate formation would not be found as the extinction of the dinosaurs occurred about 65 million years ago, well before the lands now know as Florida began to emerge from the sea.
