At GBG microgravity is our predominant survey due to its use within engineering geology. Voids can be detected providing their size and depth if large enough to cause a change in the gravitational field.
Materials of different densities within the ground cause local variations in the earth’s gravitational field. The measurement of these local variations can enable mapping of features including fault zones, voids (including caves, mine-workings and basements), along with shallow rock and buried walls. Microgravity can be used to detect both natural geological features and man-made features. On a larger scale the technology can be used to detect large geological features such as hydrocarbon traps, geothermal energy or groundwater stores.More Services
