Our SP Range of splayed wing wall headwalls are precast headwalls produced with a higher wing walls at the front of the apron.

SP precast headwalls are for inlets or outlets situated in locations with high or steep embankments or where the structure is required to provide protection to an accessory such as a flap valve, duck bill valve, stop logs or weir wall. Althon SP precast concrete headwalls offer a cost effective alternative to in-situ structures for connecting pipework discharging into open watercourses.

There are four sizes of SP headwall available catering for pipe sizes up to and including 1800mm. Each SP precast concrete headwall comes four back wall heights offering wing wall profiles to suit most applications.
