The project was initiated by Statens vegvesen, given the problems in Norway associated with slopes of marginal stability. The report will focus on installation methods that are applicable for ground improvement in soft sensitive clays, with the aim of identifying installation methods that minimise pore pressure built-up during installation as well as deformations. The methods considered include both dry and wet deep soil mixing and various other potential methods, including electro-osmotic injection of stabilising agents into the soft soil. Additionally, an evaluation of the achieved effect on strength parameters resulting from the use of wet slurry versus dry mixing is conducted
