Ground Improvement Construction

RAS Column Method is classified into machine mixing method of deep mixing method. Original soil is mixed with cement milk by force using a mixing blade to improve the ground. Drilling and mixing is executed by the dual rod system that the inner and the outer rods rotate forward and reverse. The inner rod has the head to drill firm soil with high torque, while the outer rod is for mixing. The rod rotating forward and reverse ensures high quality ground improvement with excellent homogeneity. Since the high-torque auger is used, the maximum diameter of the improvement area is 2,500mm, which will give you economic efficiency with the reduced number of the piles. In addition, the special control equipment that displays real time mixing conditions in the ground will make accurate operation and construction.
