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.
