Natural stone assessment with ground penetrating radar

Abstract

The usability of ground penetrating radar in quality assessment of natural stone deposits was tested in porphyritic granite and soapstone. The main interest was to evaluate how the soundness, fracturing, and physical defects can be studied with the method. Ground penetrating radar is a suitable and fast investigation method for natural stone evaluation, but the geological and geophysical characteristics of the rock have to be known in advance to help the interpretation of the results.
