Concrete Manhole

CPM offer a range of standard heavy duty cover slabs from 900mm to 4000mm to BS EN 1917:2002/BS 5911-3:2010 as well as a wide range of standard specials which are outside the British and European standard but are regularly used throughout the industry as well as a bespoke range of 'one offs' that require that "extra special something".

The reinforced concrete 'biscuits' are used to cap a manhole chamber and provide a base for regulating brickwork or seating/adjusting rings prior to installing the manhole lid.

CPM precast concrete chamber rings are manufactured with tongue and groove joints and comply to BS EN 1917:2002/BS 5911-3:2010 and are supplied with three nominal 50mm diameter holes for lifting purposes:
