Designed and manufactured in accordance with all current design specifications and relevant standards, FP McCann’s box culverts are available in span sizes from 1000mm to 6000mm and internal heights from 500mm to 3600mm. With our extensive range of moulds, we also strive to accommodate non standard variances, along with any other internal features requested by the client.
Based in a modern production facility at Byley, Cheshire, FP McCann’s experienced engineers and detailing team have the flexibility to quickly respond to meet any design criteria and deliver nationally to just-in-time requirements.
Supplied in either single or multiple runs, the use of precast concrete box sections in civil engineering projects is wide-ranging, from their use for directing/diverting watercourses to the provision of attenuation tanks and underpasses.
FP McCann is a member of the British Precast Drainage Association (BPDA) and their products comply with all relevant standards, as set out in accordance with ISO 9001 and ISO 14001.

Units are available in internal span sizes from 1000mm to 6000mm and internal heights from 500mm to 3600mm, with unit lengths to a maximum of 2000mm dependent on final mould configuration.
Cast in mammal ledges allow access through the culvert to wildlife without the requirement for extra site provisions.
Half round (or equivalent) channels can be cast into the floor of the units at any position with a choice of equivalent half round diameters.
Used to facilitate separate water passage through the structure.
Combined with either a channel or cast as a “vee” benching improves self cleansing flow rates.
