H6C Headwalls are precast in concrete to suit plastic or clay pipes up to 600mm and concrete pipes up to 450mm. H6C Headwalls are available with three standard backwall heights of 1100mm, 1550mm and 2050mm. Stainless steel sockets can be cast into the headwall for the attachment of gratings and other factory fitted accessories.

We cast the opening in the back wall 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.
