Kentucky's Pennyroyal Plateau—the karst landscape surrounding Mammoth Cave—contains one of the densest concentrations of sinkholes in the United States. Bowling Green, I-65 through Warren County, and the Glasgow area experience sinkhole formation that swallows roadways, disrupts utility corridors, and threatens commercial infrastructure. GeoStabilization International deploys targeted void filling and compaction grouting programs that stabilize the subsurface karst voids responsible for surface collapse—addressing the cause, not just patching the symptom.
Our in-house ground improvement engineers design injection programs using borehole camera surveys, ground-penetrating radar, and detailed void characterization to ensure complete treatment of the threat zone beneath your Kentucky infrastructure.
Kentucky's Pennyroyal Plateau—the karst terrain surrounding Mammoth Cave National Park—contains over 60,000 mapped sinkholes across a region that also supports I-65, US-31W, commercial development in Bowling Green, and agricultural infrastructure across Warren, Barren, and Hart counties. New sinkholes form when carbonate bedrock dissolves along fractures, creating subsurface voids that propagate upward through the soil column until the surface collapses—often without warning.
Our sinkhole repair approach addresses both the immediate collapse and the subsurface void system that caused it. Compaction grouting densifies the disturbed soil column above the void. Targeted void filling injects controlled-viscosity cementitious grout into the dissolution cavity itself, re-establishing structural support. For sinkholes threatening highway infrastructure, we combine grouting with ground anchor systems that tie the pavement structure to competent bearing strata below the karst horizon.
GeoStabilization International also provides proactive ground assessment for Kentucky infrastructure in sinkhole-prone terrain. Ground-penetrating radar, microgravity surveys, and systematic borehole programs identify developing voids before they reach the surface—enabling preventive grouting that costs a fraction of emergency sinkhole repair. KYTC and Kentucky's infrastructure operators benefit from this proactive approach to karst hazard management.
Emergency sinkhole repair costs 3-5x more than proactive void treatment. GeoStabilization International offers subsurface assessment programs for Kentucky infrastructure in sinkhole-prone karst terrain—using ground-penetrating radar, microgravity surveys, and systematic borehole investigation to identify developing voids before they collapse. Preventive grouting fills voids at a fraction of emergency repair cost, keeping your roads open and your infrastructure intact. The data from 8,000+ completed projects ensures your treatment program is designed with unmatched precision.
Stop patching surface symptoms. GeoStabilization International's void filling programs address the subsurface cause—restoring permanent ground stability beneath your Kentucky infrastructure.
