  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.
