<p>Microbial-induced calcite precipitation (MICP) represents an effective technology in Civil Engineering, with the potential to serve as a cost-effective, environmentally sustainable solution for various challenges, including ground improvement, liquefaction remediation, and the enhancement of concrete properties. MICP has demonstrated efficacy in sandy and loamy soils. However, its applications in expansive soils are inadequately investigated, with the majority of research restricted to laboratory settings. This paper seeks to comprehensively assess the efficacy of MICP in stabilizing expansive soils by combining bibliometric mapping with preexisting laboratory and field data, while also identifying influential factors and constraints. Minimal utilization of native bacterial strains, insufficient evaluations of durability under environmental stressors, and insufficient attention to cost-effectiveness were found to be the major limitations of MICP application in expansive soil. Additional use of other bio-based and low-cost materials for reinforcement, coupled with MICP, offers a promising advancement. This study thus offers a systematic foundation for future large-scale implementations and is critical because expansive soils present substantial hazards to infrastructure due to their swelling and shrinkage properties. The study validates MICP's capacity to improve strength and diminish swelling potential, thereby advancing eco-friendly, durable, and climate-resilient soil stabilizing methods.</p>
