Our AH12C Angled Headwalls are two part precast concrete headwalls that allow water to discharge at a 45 degree angle. This is the Environment Agency’s preferred method when discharging into a watercourse. AH12C precast headwalls comply with ‘Sewers for Adoption’ guidelines.

AH12C angled precast headwalls are available with two back wall height options with two toe extension thickness options, both available in three depths. The AH12C Headwall Range has been designed to accommodate plastic, clay or concrete pipework up to 900mm.

AH12C angled precast headwall units can be pre-fitted with a range of accessories such as Kee Klamp® handrails, gratings, flap valves, penstocks and other flow control devices.
