FP McCann’s precast concrete headwalls provide an ideal end connection point to outfall pipes into open watercourses such as rivers, culverts, collection and balancing pools.

They are a very efficient alternative to intrusive shuttering of soil embankments and costly on-site formwork with ready mixed concrete, making them particularly suitable for use in hard-to-reach locations and environmentally sensitive areas.

Where time constraints exist such as in tidal flow situations, concrete headwalls can be quickly positioned, secured and backfilled, providing immediate stability around the point of water discharge.

The FP McCann headwall range can accommodate pipe sizes from DN150 to DN2100 and is suitable for use with box culverts. Additionally, accessories such as flap valves, penstocks, silt traps, handrails and safety grating can be built in as part of the specification.

A front weir wall can be fabricated onto any of the standard headwall range, on request, and installation is quick and easy.

Key Site Safety Benefits

Safety handrails can be used with our full range of headwalls. Health and safety risks are minimised because the construction work takes place off-site and installation is quick and easy.

Please note: Bespoke grates and handrails are available on request.
