  • This study researches on global technology trend in each of composing technology, such as grouting material, grouting equipment, and construction management technology, which grouting technology has been founded upon to improve relatively inadequate domestic grouting technology and to establish the global standard for overseas expansion in the future. As far as grouting material is concerned, while High-Penetration and High-Strength micro cement ($1.5{\mu}m$) has been developed in 2000's in Japan, JinChun Kim et al. (2014) has been developing hybrid type micro cement grouting material and examining specifications of different kinds of projects and countries to analyze the trend of grouting equipment development. The specification contains detailed requisite specification for materials, mixers, pumps, agitators, and packers and it has to satisfy the standard of different countries to win global contracts. Grouting management technology can be divided into four different generations and Scandinavian countries, such as Sweden, Norway, and Finland, Japan, and South Korea are recently doing vigorous researches on the Fourth generation which merges grouting technology with ICT.
