Caves, voids, sinkholes, tunnels and
abandoned mines can lead to dangerous situations for people
and property. Subsurface voids can cover a full spectrum of
depth and severity, from collapsing sidewalks to surface
subsidence from old mine tunnels.
Locating voids and tunnels will minimize potential
liability, reduce possible work delays, and dangerous future
problems. Sinkholes and void spaces have caused damage to
highways, roads, and buildings. Before void spaces cause
damage they can be detected with several geophysics methods.
