<strong>FP</strong> <strong>McCann</strong> box culverts are available in<br />
span sizes from 1000mm to 5400mm<br />
and internal heights from 500mm to<br />
3600mm dependant on the final mould<br />
configuration adopted.<br />
A bespoke CAD design service is also<br />
available where non-standard unit sizes<br />
can be accommodated along with any<br />

Ease of installation<br />
Can be easily positioned in shallow or<br />
deep fill installations.<br />
Structural strength and long life<br />
performance<br />
Durable system meeting the design<br />
life requirements for buried<br />
structures. Minimum maintenance<br />
required.<br />
Flexible sizes and internal features<br />
Can be manufactured in a range of<br />
sizes and accommodate features such<br />
as dual cells, dry weather flow<br />
channels and mammal ledges, plus<br />
tapered and skewed units if required.<br />
Factory quality finish<br />
Off site manufacturing to relevant QA<br />
standards.<br />
<strong>Box</strong> Culvert Applications:-<br />
• Attenuation and storage tanks<br />
• Water course diversion<br />
• Open channels<br />
• Road crossings<br />
• Pedestrian and vehicle subways<br />
• Mammal crossings<br />
• Shafts<br />
• Service tunnels and ducts<br />
• Conveyor protection cover<br />
End walls, access points, vent holes,<br />
inlets, outlets, rungs, angles and splayed<br />
ends can all be added to any run of<br />
culvert. Starter bars and sockets can be<br />
added to facilitate any additional<br />
casting on site which may be required<br />
as part of the finished work.<br />

<strong>Box</strong> <strong>Culverts</strong><br />
Typical Culvert :<br />
Internal span and height from<br />
5400mm and 500mm in lengths up to<br />
2200mm (dependant on the culvert<br />
profile and span sizes)<br />
Channels :<br />
Half round (or equivalent) channels<br />
can be cast into the floor of the units<br />
at any position with a choice of<br />
diameters<br />
Benching :<br />
Combined with either a channel<br />
or cast as a “vee” benching<br />
improves self cleansing flow rates<br />

Mammal Ledges :<br />
Cast in mammal ledges allow access<br />
through the culvert to wildlife without<br />
the requirement for extra site<br />
provisions<br />
Dual Cell :<br />
Two water courses cast into a single unit<br />
Specials :<br />
Bespoke units accommodating a<br />
variety of features can be<br />
manufactured to the customer’s<br />
design requirements<br />
