Hoggin
Hoggin is: ‘Well graded gravel having clay binder. Historically used for tracks and paths but also sub-pavement over jack arches (flat or straight arches).’ Ref ‘Iron and steel bridges: condition appraisal and remedial treatment’, published by CIRIA in 2008.
Hoggin, or ‘graded hoggin’ is derived from dug gravel or pit-run gravel which includes significant amounts of clay. It is typically used in gardens to provide compacted ground cover, creating an attractive, stable, low-maintenance, semi-permeable, bound surface. This can be seen as a better environmental and less expensive method for creating pathways compared to tarmac, concrete or paving slabs, although it will not withstand such heavy traffic.
In higher traffic areas, or where significant rainfall is expected, a sub base of crushed rock may be laid below the hoggin surface. Hoggin will require regular weeding, and may need to be ‘topped up’ and eventually replaced.
