One of the authors is developing a countermeasure against liquefaction of ground supporting existing structures by combining the following two new technologies : 1) The Multiple Permeation Grouting Method, which is capable of grouting from multiple points in sandy ground; and 2) The Silica Type Grouting Materials which has higher durability and permeability in sandy soils. This paper describes the application of this method as a countermeasure against liquefaction for a belt conveyer foundation in water front areas, and the results of the laboratory tests conducted on the samples recovered at the site. As results, it was found that the strength and deformation characteristic against liquefaction of the grouted soil have been improved; It is concluded therefore that the method is a promising countermeasure against liquefaction of ground/ which supports existing structures.
