Trevi is well known globally for such complex works as the restoration of the leaning Tower of Pisa, to say nothing of their unsurpassed knowledge of dam repair works, tunneling in soft glacial soils, rehabilitation of polluted sites ... All this indicates a comprehensive competence which has found, and still finds today a never ending application in every corner of the world. 

Internationalization, integration and the continuous exchange between its two divisions are among the reasons for the success of the Trevi Group: Trevi, which carries out special foundations and soil consolidation works for large infrastructure projects (subways, dams, ports and docks, bridges, railway and highway lines, industrial and civil buildings) and secures polluted sites and Soilmec, which designs, manufactures and markets machinery, systems and services for underground engineering.
