When structures are founded on soft soils, such as clay and silt, it is often necessary to improve the properties of the soil, to reduce the risk for slope failure (landslides) or excessive settlement. Dry deep mixing is a common and cost-effective method for soil improvement. Dry deep mixing implies that a cement or cement-like powder is mixed into the soil, forming vertical columns. We have long experience of research on dry deep mixing, both with respect to the mechanical properties of the columns and how to best utilize them in design of structures in soft soil.
