Settlement or subsidence -- the distinction matters
In Bowling Green, what looks like ordinary settlement can instead be subsidence over a raveling karst void, and mistaking one for the other means specifying the wrong fix entirely.
Matching the remedy to the cause
- Geotechnical input where karst-related subsidence is suspected
- Comparing mudjacking, polyurethane lift, or deep foundation support
- Void-filling or grouting where a cavity is confirmed beneath the footing
- Re-checking elevations after the first heavy-rain season post-repair
- Documenting any residual movement for future reference
Why karst settlement can recur
Unlike ordinary clay settlement, karst-related movement can resume years later if the underlying void keeps developing, which is why monitoring after the fix matters as much as the fix itself.
