Dry Deep Soil Mixing (DSM), also referred to as the Lime Cement Column
Method, or just Cement Columns, is a variant of the deep stabilization technique
invented by Kjeld Paus almost 30 years ago. It is a form of soil improvement involving
the introduction and mechanical mixing of in situ soft and weak soils with a cementi-
tious compound such as lime, cement or a combination of both in different proportions.
The mixture is often referred to as the binder. The binder is injected into the soil in a
