H20C B Headwall

Download Datasheets

H20C B 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 B Headwalls suit plastic or clay pipes up to 1050mm and concrete pipes up to 1050mm.

H20C B Headwalls have a backwall height of 1650mm. Stainless steel sockets can be cast into the headwall for the attachment of gratings and other factory fitted accessories.

H20C B 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 H20C B Headwall weighs 3210kg / 1605kg per section.

If you require any assistance or more information please contact us by phone on 01603 488700 or by email sales@althon.co.uk

As standard our headwalls have a natural concrete finish.
We can offer coloured headwalls in 4 colours but the final shade is affected by many influences.

Our Headwall Products are available in a range of colours
