The contribution concerns modelling of hydro-mechanical processes in bentonite based sealing plugs installed in a rock environment. The motivation for this investigation is the understanding of the behaviour of the bentonite-based barriers for a deep geological repository for high-level radioactive waste. We will define a generic problem for a bentonite based plug in a vertical borehole that may be considered in different host rock environments and used for investigation of special features connected with the modelling of swelling induced expansion of the plug, which initially does not occupy the whole borehole diameter.
