Florida's void fill needs concentrate on karst limestone dissolution features across the state's central karst belt, where confirmed cavities beneath roads and structures require treatment before they progress to surface collapse — a proactive alternative to the more disruptive sinkhole repair that follows if left untreated.
It's a recurring example of the Subsurface Void & Sinkhole Problems conditions FDOT and local owners manage statewide.
Compaction grouting into Florida's confirmed karst voids restores structural support before dissolution progresses to surface collapse, a proactive treatment less disruptive than post-collapse sinkhole repair. This is one application of GSI's broader compaction grouting expertise.
Geophysical investigation for Florida void fill maps karst cavity geometry using GPR and borehole cameras, distinguishing genuine dissolution voids from the state's naturally variable limestone terrain. GSI's ground improvement solutions experience informs this approach.
Injection sequencing for Florida karst voids proceeds carefully from base upward, monitored in real time given the sensitivity of treating active dissolution features. This draws directly on GSI's mining operations work.
GSI's water infrastructure experience also informs how these Florida projects are scoped from the start.
Engineered for Florida's conditions. GSI's Florida void fill treats confirmed karst cavities proactively — before collapse — offering a less disruptive alternative to reactive sinkhole repair. Supported by engineers and our case studies.
Design/build delivery. Engineering and construction remain under one team — avoiding the miscommunication between separate design and build firms.
FDOT specification compliance. Documentation and construction methods meet state DOT standards beginning with the first engineering package.
GSI's engineers are ready to assess void fill conditions at your Florida site.
