“Paving” is the term used in stonework to describe a surface for human or vehicular travel. There are numerous colors, shapes and sizes of stone used for paving. Some paving designs may include a geometric pattern or be centered around a fire feature. Material choices run from thin stone less than 1 foot in length to true “flagging” or flagstone 3′ or longer. The chosen paving material is set on a bed of compacted aggregate that provides water drainage. Allowing water percolation away and through the construction will prevent frost from heaving the works. The joints between stones are typically filled with a porous jointing compound which also locks the stone together.
