In this research, grouting methods and the properties of grout material used currently were studied and standard test method for properies of penetratin, solidity, durability, environmental effects were suggested. The ultrafine grouts was devoloped in this study and the superiority of grouting effects was confirmed through in-situ applications. And also the refinery system for non-pollutant, good durable Silica-sol was developed and has been operated.
