Traditional engineering solutions involve excavation and import of new construction materials, resulting in waste requiring off-site disposal to landfill and a relatively high carbon footprint. Working for the Highways Agency in England, Amey proposed remediation of a failing embankment using the pioneering electrokinetic geosynthetic treatment technique. This innovative technique involves in-situ remediation of the failed soil masses rather than excavation and replacement, with the potential for reduced vegetation clearance and a much lower carbon footprint. This scheme is one of the first pilot schemes implementing the technique on a full scale remediation project and involved close collaboration between Amey, their contractors, the Highways Agency and Electrokinetic Ltd. This paper outlines the design and implementation aspects of the project and summarises the findings of the post construction verification.
