GPR technology in Monuments Conservation

GEOSERVICE works in the National Archaeological Museum of Athens providing state-of-the-art services in the field of Non-Destructive Geophysics, for the preservation of the marble statues of the famous collection of "Antikythera Shipwreck.

The applied technology is based in the well-known Ground Penetrating Radar method, especially adapted to scan specific parts of the statues to investigate their interior structure.



The main principle of conservation work is to preserve monuments as evidence of past times and cultures. They are part of history and enable us to “touch history”. Therefore, it is the task of the preservation of monuments to protect these documents as originally as possible in their existing substance and to pass them on to future generations as “genuine” cultural heritage. Recent progress in research had as result the development of new materials for the preservation of stone.

Conservation of Byzantine mural paintings using nano materials



To test the nanomaterial CaLoSiL with mural paintings, a copy of Holy Mary was produced and destroyed. Afterwards a real conservation with CaLoSiL was carried out.

Description and condition

 The mural shows a byzantine picture of Holy Mary. The copy was made by Frederike Bock in 2009. After the intentional destruction of the object the following damage symptoms can be observed: cracks, voids, sanding, delamination and missing parts of mortar and paint.

Subsurface exploration methods

We apply the latest geophysical methods in the market for the service of our clients, using up-to-date instruments and software. Our main concern is to provide accurate models of the subsurface to support the highest design needs of our clients and partners.

Downhole video inspection

The Downhole video technology started in the 1980’s. Today is the ultimate tool for the cased well inspection to identify serious problems related to the water production the condition of the well screens etc.

The technology is relatively simple and consisted to the insertion of one underwater video camera into the well, lowering the camera from the top to the well bottom with a parallel recording of the interior.
