Interclay is a benchmarking exercise involving the numerical modelling of the rheology of clays. Its broad objectives are to improve confidence in long-term predictions of the geomechanical behaviour of clay in situations relevant to the underground disposal of radioactive waste. The project is organised into three distinct phases: the first concentrates on the verification of the computer codes, the second progresses towards validation using well controlled laboratory tests as a basis and the third stage endeavours to model in situ behaviour. This document reports the work of the first stage. Four hypothetical benchmark problems (based on the highly idealised representations of the Mol underground research facility and of the Drigg LLW disposal site) are described and the results of various participants are compared. Good agreement is generally obtained and it is concluded that verification per se is no longer a significant issue. However, the results confirm the need for careful a priori assessment of the data requirements of the various computer models. In general it appears that there are few data immediately available to support state of the art computer models.
