Containment barrier at Pride Park, Derby, England
The Pride Park site at Derby occupies 96ha of derelict land close to the city centre. Approximately one third of the site was a closed landfill with a further third being an old gas works site. The remainder comprised former heavy engineering works and gravel pit workings. The River Derwent bounds the site on two sides. The objectives of the remediation strategy for the site included minimising off-site disposal of contaminated soils and ensuring that contaminants do not migrate into the adjacent river. The eastern part of the site, including the landfill and gasworks sites, was therefore contained by a 600mm wide bentonite cement vertical cut-off wall, with HDPE membrane, sealed by 1m into the underlying mudstone. The cut-off wall is some 3km long and a maximum 10m deep. The works were complicated by the need to construct the wall around 36 existing underground services. The paper briefly covers the background to the remediation of the site, describes the construction process and discusses design considerations in relation to the durability requirements of the containment barrier in the potentially aggressive environment.
