    Krakowiec clays are perceived not only as a ceramic raw material, but more and more often as geological barriers protecting the natural environment against penetration of contaminations to the soil. A number of difficulties are encountered when evaluating permeability of these clays due to specific nature of their seepage process when compared with non- cohesive soils. That is why evaluation of permeability coefficient depends on the changes of pore water pressure and drainage conditions to a large extent. A versatility of Rowe's consolidometer tests allows for monitoring consolidation and permeability. The comparison of the strain changes in time and variability of pore water pressure with the consolidation theory is required to assess the reliability of the obtained permeability parameters. The evaluation of the character of the soil strain and pore water pressure distribution for Krakowiec clays samples from selected sites is presented in the paper. Interpretation comprises of evaluation of the variability of consolidation and permeability parameters having an impact on reliability of the obtained results.
