Abstract: Abstract: This paper reports a case study on remediation of a tilted three-story reinforced concrete building, damaged by earthquake induced soil liquefaction. Low-pressure cement-sodium silicate mixed grout was utilized to conduct the remediation work. Micro-piles and jet grouting were installed first on one boundary of the building to serve as a curtain wall to protect a neighbor warehouse. Subsequently, low pressure grouting was conducted via 13 inclined injection holes. Vertical depth of injection holes was at 6.5 m below ground surface. 5-cm diameter PVC pipes with perforations at every 50 cm were pre-embedded in the injection holes before grouting was applied. Effectiveness of the adopted plan was evaluated by comparing the relative settlement of the ground floor slab, before and after the grouting. In addition, shear wave velocity of the ground next to the building site was also investigated before and after grouting to check the strength increased after grouting.
