Slate is a durable and non porous natural stone which is made up of clay and volcanic ash. Slate comes in exotic colours. It is non slip by nature and therefore excellent for flooring applications both indoors and outdoors. It has a very low absorption rate so staining is not a big concern. Slate is not affected by weather conditions and for this reason it can also be used as a cladding material. Maintenance of slate is very simple and easy.
