Investigation of the foundation system of the heritage site is a challenging task. The heritage site in the present study is Sun temple, Konark. The temple is a 700-800 years old stone masonry structure and world heritage site in the Indian state of Odisha. The investigation of the foundation details, i.e., type, depth, and horizontal extent, along with the soil layering below and around the temple premises, involves non-invasive and invasive techniques. The shielded and unshielded Ground Penetrating Radar (GPR) antenna, with a central frequency of 250 MHz & 500 MHz, and 100 MHz, are used for non-invasive investigation. In addition, invasive investigation, i.e., drilling at the top of the platform, at the plinth level, collection of samples, and characterization are performed to determine the soil layering below and around the temple premises. The GPR radargrams of the layering system corroborated with the bore logs obtained by performing the invasive investigation. The non-invasive and invasive study establishes the foundation system as a block type having a depth of 10.5 m from the top of the temple platform. The study demonstrates the efficacy of GPR as a support system for conventional invasive techniques. The paper in detail presents the GPR investigations, their inferences, invasive testing, and the corroboration of the non-invasive and invasive tests.
