Abstract
The paper presents 3D GPR investigations for location voids and loose zones in two sites in Poland: first on the area of the Old Town of Sandomierz and second at the post-mining area in the town of Siersza. The appearance of the viods and loose zones in the ground influence on the changes of the dielectric properties of the geological medium, mainly when such zones are water-saturated. The results of GPR deta interpretation allow to predict sinkhole creation in both sites under investigation.
