Traditional Manholes
The Marshalls Civils and Drainage traditional manhole range consists of precast concrete manhole rings and heavy duty manhole covers to manhole risers and drain cover slabs. They come in all shapes and sizes too from rectangular drain covers to circular concrete chamber sections.
Our traditional tongue and groove range of concrete manhole rings comply with BS EN 1917:2002 and/or BS 5911-3:2010 from 900mm to 3000mm. Although our 3660mm and 4000mm manhole chambers are not covered by the British or European standard, they do comply with all the relevant provisions of the standards.
Our range of precast concrete chamber rings are all available in BIM (Building Information Modelling) format – this is now a requirement for all government construction projects.
