Conventionally, existing methods used to be focused on simply prevention of further settlement of structures, which many problems were raised and sometimes the construction itself was not possible. Further, rough estimation of the ground, which is unseen, often incurred much trouble in the maintenance. D-ROG method is a high-tech technology that can solve these problems. The technology which injects a grout into the ground of the base, experiences permeation, compaction and fracture with 6 kinds of the cementitious materials specially in order to strengthen the ground through a number of the grouting pipes in the 1st, and then makes settlement structures restored by producing even pressure between the strengthened ground and basement, with injections being carried out from multi-points, with circulation and repetition.
