We are thrilled to announce that our B3224 Roundwaters Retaining Wall project has been shortlisted as a finalist at the 2025 Ground Engineering Awards, in the category ‘UK project with a geotechnical value between £500K and £1M’.

Developed by WSP in collaboration with Somerset Council, the scheme involved the installation of a sustainable geotechnical solution to stabilise a failed embankment. The embankment is located on the B3224 in Exmoor National Park, spanning across the Larcombe Brook valley. The failure occurred during storm events which caused a significant portion of the embankment and adjacent highway to collapse. Following an optioneering exercise and ground investigation, a sheet piled solution adopting Giken Supercrush technology was taken through to detailed design. Walters developed a robust construction phase plan, minimising potential impacts associated with extreme water flows, temporary stability and plant operations, and all within a working area of no more than 6m width. All parties worked collaboratively to ensure site queries were dealt with proactively, providing regular updates to the community. Construction was completed safely 3 weeks ahead of programme, minimising impact on the local economy and the surrounding environment.

The award ceremony will take place in London in June this year to celebrate outstanding achievements across a number of projects. Good luck Team Walters!
