Soil consolidation process influences the settlement that occurs. Soft soil requires long period of time (decades or even centuries) in order to achieve total consolidation. It is impossible to wait for the whole process of consolidation because buildings are about to be constructed on the land. Efforts to accelerate consolidation of soft soil process have been conducted several times, for example using preloading, air compression, dewatering, and water reservoir. However, these efforts also require extensive period of time. Actually, the process of soil consolidation and the process in which water come out of soil pores (or drainage process) are quite the same. In this process, soil permeability holds an important role. Thus, the efforts to plant drain columns into the soft soil layers are required in order to accelerate water to come out of soil pores, that it will then also accelerate the consolidation process. Geosynthetic used in the acceleration process of soil consolidation is vertically planted as deep as the soft soil layer. The objective is to evacuate water inside the soft soil pores rapidly. The acceleration of soil consolidation depends highly on the drainage capacity of the geosynthetic, which works as vertical drainage. The larger the drainage capacity of the geosynthetic, the faster the soft soil consolidation process and the shorter the soil consolidation period. The optimal condition results from geosynthetic with the largest drainage capacity. .
