Storage is one of the most widely applied methods of neutralisation of wastes, prevailing over thermal, chemical and biological treatment. Waste disposal site must be harm-less for the natural environment and for the human’s life and health. Its sealing must be reliable. However, the recently used synthetic liners are not sufficient. Experiments showed that the proper protection of the natural environment against the interaction with wastes may be achieved by using naturally occurring grounds, or by composing artificial mineral sealing barriers. The deposits to be used a as a barrier must have specific characteristics required by the binding regulations. On the example of the clays from the pit in Budy Mszczonowskie, the paper presents the range of investigations needed to evaluate applicability of the Neogene expansive soils as the sealing barriers.

Projects for the storage of municipal waste involve systems of successive safety barriers consisting at least of a geomembrane and a natural mineral layer. “Poznań Clay” are among materials which can be used as a mineral layer. In this paper mineral layers standards from different countries are described. Studies of the important properties of “Poznań Clay” such as hydraulic conductivity, mineral composition, and void ratio are presented. Samples with undisturbed and disturbed structure were examined. Differences between properties of these samples are negligible.
