This paper presents the injection efficiency of 2.0 shot system which was verified by strength and injection time. In order to perform this study, laboratory model tests and field tests are carried out. The laboratory model tests consist of the test of injection time for verifying the injection ratio, and the tests of homo-gel and sand-gel strengths for estimating the characteristic of strength. It is found that the injection ratio of 1:2 shows the best seepage into the ground. The results of the strengths are also larger than other injection ratio. The large strength will also be expressed by field tests at construction site.
