[0002] Mortared flagstones are often used as retaining walls in roadbed projects or slope protection of some highways. They are masonry structures built with mortar and rubble stone layers. The stone layers are irregular in shape, with a thickness of about 15 cm on the short side. Sometimes blocks are also used. It depends on the shape and size of the rubble stone. There is no clear dividing line. Generally, those close to a rectangular block are flagstones, and those close to a cube are blocks.
