Limestone is a sedimentary stone that is created by small particles of stone or rock compacted together through pressure. It is a building material that is well regarded for its hardness, imperviousness and durability.

What is limestone?

Limestone is a sedimentary stone that is formed at the bottom of marine waters, lakes or caves. One of its identifiable properties is the composition of more than 50 per cent calcium carbonate. Small particles of clay minerals, quartz, pyrite and siderite can also often be found in varying quantities within the limestone.

What are the types of limestone?

There are several varieties of limestone that differ in how the stone is formed, its composition and its appearance.

Travertine, for example, is a type of limestone that is often found in cave environments and formed when the water evaporates and calcium carbonate is deposited in the cave’s surface. As these deposits accumulate, the cave formations such as stalactites and stalagmites are created.

Other types of limestone include Chalk, Tufa, Lithographic, Oolitic, Coquina and Fossiliferous Limestone.

Some limestone is denser and more consistent than others. Our range of limestone concentrates on the denser scale of the stone making it suitable for most applications.

What are the uses of limestone?

Traditionally, limestone was used to create ancient landmarks such as the Egyptian pyramids. In more recent times, it has been a popular construction material across Europe and North America to create buildings, build roads and used frequently in the rail industry.

Limestone is also used for flooring and cladding as well as kitchen and bathroom benchtops. The minerals of limestone are often utilized in the manufacturing of glass, textiles and even paint.
