Natural and consolidated clay soil used in land-fills is generally used for forming floor and ceiling coverings and for the formation of side berms. Clay soil layers are effectively used to adsorb contaminants such as leachate and organic liquids. In the previous researches; it is stated that as a result of leachate passing through the clay soil, the structure of the clay soil deteriorates, and changes occur in the permeability of the ground over time. Therefore, it was found that the clay soil alone was not sufficient to provide impermeability.
