1950   Establishment of SELI, with mission from the outset to design and apply new techniques for tunnel boring.

1969 For the first time in Italy, SELI adopts mechanised excavating techniques with TBM for the 5 km tunnel at Brasimone, opening up a new era in a sector which until then had been the exclusive domain of the use of explosives.

1970 SELI transfers headquarters to Rome.

  1972   Through its founder, engineer Carlo Grandori, SELI collaborates with Robbins of America to develop the first double-shield telescopic TBM, the type that came to be employed in a wide range of projects including the Channel Tunnel.

  2006 SELI establishes INNOTEK, a company specialising in the research, development and commercialisation of chemical products and tools for specific use in underground works.

  2007 SELI launches the construction of a new larger and more advanced production factory at Aprilia, which enables its manufacturing capacity to keep up with growing market demands.
