To protect ground composed of loose sand or sandy soil, and structures constructed thereon against seismic liquefaction disasters, said ground is improved and reinforced by a four-stage method At the first stage, a specially formulated mortar impregnating material is injected by a specific impregnating machine through a given array of injection points into the ground to achieve a first effect by the first impregnation by consolidation. At the second stage, an injection pipe having a distal penetrating end unit is forced or driven into the ground to obtain pile-like compression effect At the third stage, a specially formulated cement impregnating material is injected into the ground to obtain a third or consolidation effect. At the fourth stage, the impregnation of the cement material under pressure causes soil particles to be solidified by the penetration thereof.
