Limestone is a sedimentary rock. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate (CaCO3) from lake or ocean water.

It is a natural stone that is usually hard enough to resist weathering but soft enough to be worked by Banker Masons. Limestone, particularly portland limestone, became popular in the 19th and 20th centuries for constructing buildings such as churches, banks and houses.

At PMJ Masonry, this natural stone is popular with cladding projects that require/include intricate carving details to add a unique edge. PMJ Masonry undertook a project at 10 South Parade in Leeds where German jura limestone was used to complete all external and internal works. At the entrance to the building, “10SP” was carved into the stone by our time served masons to make a building identifier and add a special feature to the project.
