H10C A Headwalls are precast concrete headwalls to suit plastic or clay pipes up to 750mm and concrete pipes up to 750mm. H10C A Headwalls have a backwall height of 1250mm. Stainless steel sockets can be cast into the headwall for the attachment of gratings and other factory fitted accessories.

H10C A Headwalls have sloped wingwalls

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. 

The H10C A Headwall weighs 1947kg
