Project Reference


Trevi Fountain, Rome, Italy

The world's famous Trevi Fountain, Italy, was restored with GMA PrecisionBlast and IBIX Helix systems. The cleaning process has been a delicate phase of conservation work as any lack of calibration could cause irreparable damages to the historical monument.

GMA’s PrecisionBlast is ideal for restoring the fountain’s travertine and marble surfaces due to its superior cleaning rate and low garnet consumption. GMA Garnet’s natural, chemically inert garnet abrasive has been a safe choice for on site workers removing thick deposits (black incrustations) and limestone encrustation on the fountain’s cliff.
