The main subject of the paper is the practical application of the existing geotechnical and geo-environmental engineering techniques for the purpose of ground characterisation in landslide areas. Special interest is given to the landslide issues in difficult geotechnical and geological conditions and evaluation of soil design parameters by in situ tests. In the paper, usage of CPTU connected with reference laboratory tests, GPR and other monitoring techniques in landslide and potential landslide areas are presented. Research was based on investigations in Polish opencast mines, Carpathian flysch sediments and Norwegian clays. Presented data are based on the exemplar landslide projects. The background of presented CPTU studies is slope stability evaluations of the Polish opencast brown coal mines undertaken during a research stay at the Norwegian University of Science and Technology (NTNU) with support of the Norwegian Research Council and NATO Advanced Fellowship Programme. Landslide investigations by GPR and GPS technique were performed on Carpathian flysch sediments in Lachowice and Wapienne (Poland).
