Althon concrete headwalls are available with numerous factory fitted accessories. Headwalls can be delivered to site with Kee Klamp® handrails, gratings in various configurations (outfall grilles, cranked, sloped etc) as well as more specialist accessories such as flap valves, penstocks and duckbill valves.
We also supply headwalls with dissipation blocks, stepped baffle blocks, orifice plates and cascade panels to control, regulate and dissipate the flow of water discharging from connecting pipework through the headwall down the spillway before entering the watercourse.
The pages below detail some of the factory fitted accessories available with our precast headwalls.
