H20C J Headwalls are two piece precast concrete headwall structures with rebated joints to be assembled on site around the drainage pipe and locked together by means of stainless steel cast-in sockets and brackets. H20C J Headwalls suit plastic or clay pipes up to 1650mm and concrete pipes up to 1500mm.

H20C J Headwalls have a backwall height of 2130mm. Stainless steel sockets can be cast into the headwall for the attachment of gratings and other factory fitted accessories.

H20C J Headwalls have a wingwall profile of 1:3

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 H20C J Headwall weighs 3450kg / 1725kg per section.
