H20C 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.

The H20C Headwall Range caters for plastic or clay pipes up to 1650mm or concrete pipes up to 1500mm. H20C Headwalls are available with three standard backwall heights 1250mm, 1650mm and 2100mm.

H20C Headwalls are available with three different wingwall profiles, sloped, horizontal and chamfered

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.
