SP27I 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. SP27I precast headwalls have been designed to suit plastic and clay pipework up to 1200mm and concrete pipework up to 1350mm.

Althon SP27I 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 SP27I headwall weighs 8500kg / 4250kg per half.
