How do you scan a sinkhole?
Ground Penetrating Radar (GPR) is the best way to detect sinkholes. A GPR survey is a low-risk method to determine the location of sinkholes. This can form part of a risk assessment to check the integrity of the ground or to determine the extent of voids when remediation planning.
Who inspects for sinkholes?
Professional geologists and geotechnical engineering consultants with professional geologists on staff can perform a variety of tests to attempt to locate buried cavities that might form sinkholes. These tests may include ground-penetrating radar or electrical resistivity surveys and soil borings.

A development hole is dug by a builder at the onset of a new build to dispose (incorrectly) of debris. A lot cleaning hole is built toward the end of the foundation, and a clean-up hole is done when the job is completed and the company opts to bury the detritus of building.
Can large sinkholes be fixed?
If the sinkhole is not affecting a house or other structure, and has a reasonable size — 2 to 5 feet in both diameter and depth — then you can repair it yourself. A large sinkhole will most likely require excavation and a more complex filling operation.
