In recent years, the placing of clay in clay cores of several embankment dams has been controlled by the use of a specification based on an acceptable range of undrained shear strength. The method has enabled the required properties of a non-cracking and plastic clay core to be readily tested. Measures to increase the water content of clays have been developed by contractors at different sites to achieve the required shear strength. The experience gained, especially with boulder clay at cow green dam; and Wadhurst clay at Bewl Bridge and Ardingly Dams are described. The problems and limitations of the method are discussed.
