SP Splayed Wing Wall Headwalls

Althon SP ‘Splayed Wing Wall Headwalls’ are produced with a higher wing wall at the front of the apron.  This makes them ideal for inlets or outlets where situated in locations with high/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 size of concrete headwall comes with six depths of toe and four back wall heights offering wing wall profiles to suit most applications.

All SP concrete headwalls are cast to suit the diameter and type of pipe being used and can be provided with fixings cast in at the time of manufacture to accommodate gratings, trash screens, flap valves, ladders, guardrails and flow and depth monitoring equipment.
