In the chemical grouting for the improvement of the cohesive soils, the hydrofracture occurs in all cases. The object of this study is to investigate the mechanism of strength increase of cohesive soils by grouting. The increase of strength by grouting depends upon the formation of solidified grout, the consolidation by the injection pressure and moreover the cementing action between the cohesive soil and the liquid dehydrated from the solidified grout. These factors are influenced by the grout itself and the ground condition, such as the strength of cohesive soils before grouting, the exchangeable cation, and the buffer capacity of soil.
