Ground improvement work by deepmixingmethods using a binder is becoming the
most popular method in construction industries. The deep soil stabilization technique is
often an economically attractive alternative to the removal of deep peat or use as a deep
foundation (Kazemian et al ., 2010). The essential feature of deep soil stabilization is
that a column of stabilized material is formed by mixing the soil in place with a 'binder'
and the interaction of the binder with the soft soil leads to a material that has better
engineering properties than the original soil (Hebib and Farrel, 2003; Kazemian et al .,
2011).
