SP27L precast headwalls are produced with wing walls 1050mm high at the front of the apron. SP27L 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. SP27L precast headwalls have been designed to suit plastic, clay and concrete pipework up to 1500mm and have a backwall height of 2350mm. SP27 L precast headwalls are manufactured in 2 sections. Althon SP27L 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.

SP27 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 SP27L headwall weighs 9400kg / 4700kg per half.
