Backfill is compactable material free of rocks that will not pass
through a 30mm sieve and free of broken concrete, brick,
rubble, wood, glass, rubbish, steel or other metal objects that
could damage cables or affect the operation of electronic cable
locators and is used within 400mm of cables and conduits as
backfill.
Cables that are run from an equipment room, housing or
equipment box to another equipment room, housing or
equipment box. Examples such as; signal cables, high voltage
signalling or power supply cabling, fibre optic cables, etc. Also
