%X The southeastern region of England, characterised by its geological setting, is particularly prone to dissolution features. These natural phenomena present substantial risks to both new and existing structures, as well as to the safety of the individuals inhabiting them. The potential repercussions of these hazards vary widely, spanning from minor issues like differential settlements to the gravest concern¡ªthe formation of sinkholes, which can lead to severe property damage and pose significant threats to lives. In response to these geological challenges, various methodologies have been employed to safeguard structures and communities. One such approach involves the strategic injection of compaction grouting. This paper¡¯s primary focus is to comprehensively analyse the effectiveness of compaction grouting in a typical scenario where new properties are constructed over karstic areas, which are known for their complex and challenging geological characteristics. The findings and observations from this study strongly suggest that compaction grouting emerges as a highly effective solution for addressing karstic areas, particularly when other conventional mitigation techniques prove impractical. The depth and spatial distribution of dissolution features in such areas often limit the applicability of alternative methods. Compaction grouting, by contrast, demonstrates its ability to provide substantial reinforcement, enhancing the structural integrity of the ground and significantly reducing the risk associated with sinkhole formation and other related hazards. As such, it stands out as a valuable tool in the arsenal of strategies employed to protect against the geological challenges prevalent in the southeastern region of England.
