Stone masonry is perhaps the oldest form of masonry, as the first attempts at masonry construction were crude stacks of selected natural stones. As tools and skills improved, stones were shaped into geometric units. Early masons laid stones within soil or inbedded in clay and this evolved into sawn units laid in lime mortar or laid dry.
Today stone masonry typcially takes on one of three forms:
1) Full Bed Stone Veneer
2) Adhered Thin Stone Veneer
3) Anchored Thin Stone Veneer
