H8C Headwalls are precast concrete headwalls to suit plastic or clay pipes up to 600mm and concrete pipes up to 450mm and can be factory fitted with penstocks to suit pipework up to 400mm.
H8C Headwalls are available with three standard backwall heights of 1150mm, 1600mm and 2100mm. We cast fixing points for the penstock into the backwall of the headwall so that the headwall does not have to be drilled on site.
We cast the opening in the back wall of our precast concrete headwalls to suit the pipe diameter and material of the pipe being used. We can cast multiple pipe openings, elliptical, square or rectangular culvert openings into any of our headwalls. We can also cast pipe openings into the wing walls of our headwalls.
