This study has been carried out with the purpose to investigate how surface resistivitymeasurements, geotechnical CPTU-R soundings and knowledge about the soil chemistry can contribute to a more complete picture of the presence of quick clay. The intention was to compare and complement surface resistivity measurements with cone penetration tests with resistivity measurements (CPTU-R) and measurement of the total penetration resistance, which gives the total skin friction along the rods, together with bothgeotechnical and chemical analyses on the specimens in the laboratory.
