SP15M precast headwalls are produced with wing walls 1400mm high at the front of the apron. SP15M 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. SP15M precast headwalls have been designed to suit plastic and clay pipework up to 1200mm and concrete pipework up to 1050mm. The backwall height is 2350mm. Althon SP15M precast 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.

SP15 precast headwall units can be factory fitted with a range of accessories such as flap valves, penstocks, Kee Klamp® handrails and a selection of gratings depending on the application. The SP15M headwall weighs 7090kg.
