Cave detection with GPR and seismic methods

In the last few years building sites have been extraordinarily overestimated on the hilly part of Budapest, where protected caves can be found. Thus, new buildings are built on the unbuilt areas, while on the already built-up houses are enlarged. If we close the swallers we stop the growth of voids and stalagmites. It’s important to know the size, position and depth of natural voids and cavities before building or reconstruction. We used Ground Penetrating Radar (GPR) and shallow seismic measurements to detect these objects.
