H28C 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. H28C Headwalls are ideal for situations where multiple pipes enter the back or side walls of the headwall.

H28C Headwalls will also accommodate two pipes up to 1050mm plastic each or 900mm concrete

We can cast multiple pipe openings into our entire headwall range. Please enquire for further information.

The H28C Headwall Range caters for plastic or clay pipes up to 1650mm or concrete pipes up to 1500mm. H28C Headwalls are available with three standard backwall heights 1250mm, 1650mm and 2100mm.

H28C 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.
