Archaeo-geophysics, Void and UXO detection

Artificial or natural subsurface voids (cellars, caves, etc.) can be detected by geophysical methods. It is advised to make a geophysical survey for void exploration before construction or when soil mechanical problem is indicated. Unexplored voids and caves are real danger all over the world but using geophysical survey makes it safer.

Archaeological application of geophysics is a relatively new discipline. Buried buildings, tools made of metal, or even burned down settlements can have such an effect in the soil that we can detect with geophysical methods. The aim, also in this case is the favourable cost. Making geophysical investigation over a given area is much cheaper than a total archaeological excavation. Using the data provided by geophysics can give the way, where to start the excavation.

The two world wars in the last century have left countless unfired munitions, bombs and other military equipment behind. They are hidden in the soil and the vegetation and can turn up during building processes causing tragic situations. This has occurred many times in the past. With a sufficient and safe magnetic survey on the area, these problems can be foregone. After this, the deactivation of them is the resort of the demolition experts.
