Our precast headwalls for culverts offer a Cost Effective alternative to in-situ structures for connecting Pipework discharging into Open Watercourses. All Drainage pipes discharging into Open Watercourses, such as Swales, Ditches, Ponds and Rivers, should be fitted with an appropriate Althon Headwall. Althon Headwall units can be Pre-Fitted with a Range of Accessories such as Flap Valves, Penstocks, Kee Klamp Handrails and a selection of Gratings dependant on application.

Althon culvert headwalls recess the inflow and outflow at the end of the pipe or culvert into the slope to improve entrance flow conditions, to anchor the pipe and prevent disjointing due to excessive velocities. Precast Headwalls also control erosion and scour resulting from excessive velocities and turbulences and prevent adjacent soil from sloughing into the watercourse opening.
