H8C A Headwall

BIM Available

Download Datasheets

H8C A Headwalls are precast concrete headwalls to suit plastic or clay pipes up to 600mm and concrete pipes up to 450mm. H8C A Headwalls have a backwall height of 1150mm. Stainless steel sockets can be cast into the headwall for the attachment of gratings and other factory fitted accessories.

H8C A Headwalls are cast 150mm thick to provide a longer design life and greater cover to reinforcement.

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 H8C A Headwall weighs 1975kg

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
