Trevi Spa carried out the construction of the 4 Frankfurt perimeter wall

Trevi Spa carried out the construction of the perimeter wall, serving as foundation and protection of the excavation planned for the 4 skyscrapers of the Frankfurt project, as a diaphragm wall and, in this case, through two different methods.

Basically, the excavation of the foundations is carried out by a mechanical bucket. However, due to the resistance of the limestone banks, a Soilmec Tiger SC-135 hydraulic cutter is also used, in order to reduce the impact generated by the vibrations on the adjacent structures.
