The permeating solidification method is adapted from the fluid chemical agent injection double packer method, and special silica is introduced by permeation into soft sandy ground. The compact installation rig uses fine injection pipes, and by injecting a highly permeable permanent fluid agent, pin-point improvement is possible at sites where countermeasures to liquefaction are needed.
Due to these characteristics, installation has little impact on structures and is possible at facilities that continue to operate, making it a highly economic method.
