Once again Trevi Group has made its mark in the field of underground engineering. Thanks to a newly designed hydromill, the Group now has the capability of building slurry walls down to a depth of 250 meters, an unprecedented distance underground considered unthinkable until today. The 250-meter depth exceeds by over 100 meters the maximum limit ever reached.

The record is significant not only for the application, but also for the expertise required to manage the soil and deep waters, as well for the design of a machine able to excavate to such depths.

The important experiment, conducted at a site that reproduced actual operating conditions characterized by a variable geological composition, also has special relevance because it received the scientific support of the University of Bologna, the Polytechnic University of Turin and the Marche Polytechnic University.

The test provides further validation of the synergy among the different divisions of Trevi Group (Trevi Spa and Soilmec Spa) and opens up new horizons for participation in complex projects of international scope. In particular, the new technology designed by Trevi allows engineers to confront and solve complex geotechnical problems involving hydraulic and other infrastructure requiring the construction of deep slurry walls.

Soilmec, the mechanical division of the Group, made a fundamental contribution to the success of the experiment with the design and engineering of the new Tiger hydromill, to now the only machine in the world able to reach a depth of 250 meters. This exceptional result was also made possible thanks to the Soilmec-patented DMS system that enabled real time monitoring of the principal excavation parameters and thus allow control of the verticality.

As CEO of Trevi, Stefano Trevisani commented: "We are truly proud to have rose to such a challenge and achieve a goal no one else had attempted in the past. For us, the record of 250 meters represents a feat of design and technology. Once again, Trevi Group has redefined the limits of underground engineering with solutions that are certain to make an important contribution to highly complex projects previously considered unfeasible. Thanks to our efforts, the Group will be able to seize new opportunities in the future."
