Precast Concrete Headwalls

Althon

Precast concrete headwalls offer a cost effective alternative to in-situ structures for connecting pipework discharging into open watercourses such as rivers, ditches, ponds and swales.

All drainage pipes discharging into open watercourses, should be fitted with an appropriate 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 cast openings into the back wall of our concrete headwalls to suit the pipe material and diameter being used for ease of installation. They will also set the invert level as requested and draw for approval prior to manufacture if required.

Althon 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.
