The ground improvement methods for the soft soil can be categorized according to the manner of treating the soil [9]. Mass improvement is the method that is able to improve the soil by modifying either its physical or chemical properties, or both of them in such a way that the soil becomes consistent, hence the strength is increased and deformability and permeability are reduced. This can be done by compaction or consolidation acceleration methods, or by stabilizing reagents. The most popular chemical binders are lime and cement, and their role is to bind the particles and aggregate them together, consequently improve the soil structure and properties. While the compactions and consolidation methods take rather a long time for the soil to consolidate (months to years) especially with the cohesive soil [10], the stabilizing reagents effect can be seen immediately [11] and approximately after 1 week the construction site can be ready. This is one of the reasons that make this method mainly be used in infrastructure projects [9].
