While the Grouting has been used to reinforce the foundation of structures in wide range of application, there need complementary measures against problems such as pollution, durability, influence on the adjacent structures. Compaction Grouting, the injection of a very stiff, 'zero-slump' mortar grout under relatively high pressure, displaces and compacts soils. It can effectively repair natural or man-made soil strength deficiencies in variety of soil formations. In this paper, on the basis of the case history constructed in this year, a study has been performed to analyze the basic mechanism of the Compaction Grouting, Also, the effectiveness of the ground improvement and the bearing capacity of the Compaction Pile has been verified by the S.P.T and core strength.
