Limestone is a sedimentary rock made up of layers of calcium carbonate formed from the accumulation of organic matter in shallow seas, which is then turned to stone by millions of years of pressure. Limestone comes in a variety of density and hardness and some limestones are as tough as granite making an extremely hard wearing and durable patio paving stone or internal floor tile.
Most types of limestone have pale colouring, ranging from warm neutral shades of oatmeal and cloudy white to dappled blue, green and grey, but there are dark shades. Limestone is cool & elegant & looks in classic/contemporary design.
This is a porous sedimentary rock. As a surface it can be quite soft and stain quite easily. The risk of potential stains can be largely averted by impregnating or sealing the surface of the limestone. Before doing this, make sure the surface is well cleaned.
Limestone is very common in architecture, especially in North America and Europe. was most popular in the late 19th and early 20th centuries. Limestone was also a very popular building block in the Middle Ages in the areas where it occurred since it is hard, is durable, and commonly occurs in easily accessible surface exposures.
