H8C Headwalls are precast concrete headwalls to suit plastic or clay pipes up to 600mm and concrete pipes up to 450mm. H8C Headwalls are available with three standard backwall heights of 1150mm, 1600mm and 2100mm. Stainless steel sockets can be cast into the headwall for the attachment of gratings and other factory fitted accessories.

H8C Headwalls are cast 150mm thick to provide a longer design life and greater cover to reinforcement.

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.
