ECO 1

All Althon headwalls are manufactured using a trademarked eco1™ concrete mix design. The standard eco1™ concrete mix, which is a Cement & GGBS blend, significantly reduces C0²e emissions by 50% when compared to a standard CEM1 concrete mix. In addition to eco1’s™ environmental credentials; it achieves Design Chemical Class 4 and Design Sulphate Class 4 making Althon headwalls suitable for use in aggressive environments.

Althon headwalls can also be manufactured using other proprietary mix designs for even greater carbon savings.

C0²e stands for Carbon Dioxide Equivalent

C0²e is a unit of measurement used to express the amount of greenhouse gasses emitted because of human activity.

Great Yarmouth's Herring Bridge Project

In 2023, Althon supplied a number of precast concrete headwalls, to Great Yarmouth’s Third River Crossing (Herring Bridge). All of these headwalls were made to order, and the majority of these were supplied with fitted accessories such as Kee Klamp Handrail, HDPE Non return Flap Valves, and Pond Liner Brackets at our customer’s request. One of the benefits of opting for pre fitted accessories, means there is less time spent on installation; saving valued time for contractors.
