Passive site stabilization is a developing technology for in situ mitigation of liquefaction risk without surface disruption and involves slow injection of stabilizing materials into the liquefiable sand. In this study, colloidal silica injection was performed in a pilot-scale facility having dimensions of 243 cm by 366 cm in plan and 122 cm in depth. The pilot-scale facility is the largest of its kind in the United States. It is equipped with electrical conductivity cells which provide real-time monitoring of grout advancement in the soil. Injection rates ranging between 135 and 9000 ml/min/well were used to investigate the optimal rate for grout delivery. In low injection rates, colloidal silica sank instead of traveling horizontally.
