Lining systems are more and more used to provide an environmental protection to the industri.al and domestic waste disposals. The behaviour of such lining systems can be critical during their installation and the placement of waste. First measurements from an experimental site are described. Two lining systems, HOPE geomembrane and bentonite membrane were installed in experimental cells with slope of 1/2 and 1/1 (vertical/horizontal). As the experimental program is still in work only information on displacements and behaviour of a bentonite membrane with its protective layer is available and discussed.
