BAM, Environment Agency and Tarmac trial ultra-low-carbon mixes on Hexham Flood Alleviation Scheme
Posted 12th May 2023
In a UK first, BAM, the Environment Agency and Tarmac have successfully trialled the use of two low-carbon concrete mixes in permanent works on the Hexham Flood Alleviation Scheme.
A duo of ultra-low-carbon concretes, developed by Tarmac to new specifications and compressive strength class C32/40, now form the base and walls of a new flood-defence structure designed to protect the town and mitigate against flood damage.
The trial has been delivered and funded by the Environment Agency’s Collaborative Delivery Framework Hub A, a collaboration between the Environment Agency, Arup, and BAM, as part of a wider project to deliver flood-defence schemes across north-east England.
The culmination of an 18-month project, from planning to delivery, it is the first time that low-carbon concretes developed by Tarmac have been used in permanent works.
