Asbestos Cement Conduits

Product description

Hard, brittle material, usually grey in colour with low asbestos content (up to 30 per cent). Asbestos Cement conduits were mainly used to convey HV and LV cables into and out of substations, buried under road crossings, containing cables inside or being empty, used as spares alongside roads or buried in the footpath.Extensively used in pit and duct system in Sydney CBD. Sometimes concreted in substation slabs. The use of AC conduits was stopped around 1987, from that date FRC (fibre reinforced concrete) has been used.


Asbestos has been identified in the fibre-cement material in HV cable joint covers and cable trench covers. Asbestos has also been identified in the moulded cement material in cable conduits. Asbestos may be present in the troughing used to encase joints, both direct buried and in pits.

Product identification

Sometimes it is hard to distinguish asbestos cement conduits from cement conduits, the best way is to always take a sample and test. When broken, asbestos-containing conduits will have visible fibres, whereas non-asbestos material will have a clean homogenous break.
