Gravel as it occurs naturally is usually known as either “dug gravel” or “pit-run gravel”. Such gravels often contain a considerable amount of clay or dirt (binder)‚ which if the material is required for road base or surface work‚ is an advantage. This material is known as Hoggin and when compacted can make a very stable surface. The picture is a representation of Hoggin, however this product is likely to vary so please request a sample prior to ordering.
