The paper concerns significance of properly carried out saturation procedure and its role in evaluation of undrained response of heavy preconsolidated cohesive soils. In particular the saturation criteria are addressed which should be fulfilled during saturation of preconsolidated clay specimens of various plasticity. Influence of incomplete saturation on shear strength parameters is briefly characterized. On the basis of experimental data the back pressure method is shown to be the most efficient method in obtaining full saturation in overconsolidated clay of various plasticity. Analysis of the test results made possible to propose full saturation criteria for low, medium and high plasticity clays which are based on reduced value of Skempton’s B parameter.
