Dynamic injection method increase the penetration of grout material and apply the grouting of small and low permeable crack in rock mass. This paper report the results of in-situ dynamic injection under high water pressure condition by using of the developed system reported Part1. This test used the borehole drilled in collaboration study between JAEA and AIST and the budget is a part of contract study from NISA.
