Abstract: Sinkholes present significant challenges to infrastructure, necessitating thorough investigation and effective remediation techniques. This paper examines a case study of a persistent sinkhole along a driveway in Nashville, Tennessee, where repeated pavement depressions occurred despite prior repair efforts. The study involved site inspections, drilling, analyses of soil and rock properties, and groundwater evaluations. Three repair methods were considered: traditional inverted rock filter, a land bridge construction, and compaction grouting. Taking into account technical feasibility, site-specific factors, and budget constraints, compaction grouting was selected as the most suitable approach. The paper details this solution, covering the grouting process, materials used, and construction specifications. The study’ s outcomes aim to inform and improve design standards and construction techniques for sinkhole repairs in Tennessee and comparable geological areas.
