Mass Stabilization of Organic Soils and Soft Clay
Nenad Jelisic, Mikko Leppänen

Mass stabilization is an environment friendly soil improvement method where the stabilizer is mixed into organic soil or soft clay. Mass stabilization is carried out by a tool previously installed on an excavator machine. Mixing in both horizontal and vertical directions is carried out so that a homogenized stabilized soil block is formed through the effect of the stabilizer. The thickness of the block is varied according to the height of the embankment, between 1 and 5m. Embankments can be founded on mass stabilized soil in the same way as on natural firm soil layers, such as moraine or gravel. The 5 performed mass stabilization projects are summarized in this paper. Of these 5 projects, 1 was performed in Finland and 4 were performed in Sweden.
