Limestone is classified as a sedimentary rock in which calcium carbonite is the main ingredient. Most of this comes from the remains of living creatures such as coral polyps that roamed this earth millions of years ago. Remnants of these creatures can be seen frozen in time fossilized in the rock itself and preserved for thousands even millions of years. The most famous limestone creation on our planet would have to be the Great Pyramid of Giza in Egypt. These pyramids are constructed from huge blocks of limestone that still stand today. Limestone has many different uses other than paving and is commonly used as a filler for foundation stability. Many buildings were constructed using limestone although that practice has been outdated by using a lighter material that is more readily available, concrete. Being so heavy makes limestone a poor candidate for the construction of walls and ceilings but that same property makes limestone pavers one of the best, most durable materials we use for driveways, patios, and walkways. Limestone pavers come in a variety of shapes, colors, and sizes to suit your taste. Keystone Pavers are a type of limestone that is locally mined in the Florida Keys. These naturally created pavers are highly sought after for their earthy look and extreme durability. We use only the most durable and high quality limestone pavers.
