This study examined the effectiveness of a chemical grouting method as a liquefaction countermeasure for existing detached houses. The study used a combination of centrifuge shaking table experiments and numerical simulations, to investigate this method. The numerical model was validated based on its ability to accurately reproduce experimental results regarding excess pore water pressure and relative settlement between the house and the ground. Results showed that the skirt-type improvement is a more economical solution that effectively suppresses settlement while maintaining house stability through its rigid frame effect. In addition, the method enhances disaster resilience by reducing repair needs and supporting post-earthquake habitability of houses, thereby contributing to faster community recovery.
