H28C G 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 G Headwalls suit plastic or clay pipes up to 750mm and concrete pipes up to 750mm

H28C G Headwalls will also accommodate two pipes up to 750mm plastic each or 750mm concrete

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

H28C G 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.

H28C G Headwalls have chamfered 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 H28C G Headwall weighs 3555kg / 1778kg per section
