Karst is a complex geologic environment that is associated with the dissolution of soluble rock such as limestone and gypsum. Spotlight uses non-invasive geophysical methods such as microgravity, electrical resistivity imaging, MASW, and GPR to help characterize karst conditions for applications that include:

​

• Mapping karst features beneath power plant infrastructure.

• Locating karst features within and below dam embankments.

• Identifying voids beneath airport runways.

• Assessing voids and soil piping within gypsum.

• Mapping the extent of potential karst hazards beneath roadways.

• Identifying karst conduits beneath dry coal ash ponds.

• Assessing karst conduit pathways within contaminated sites.
