Trevi has patented an innovative system allowing to install pseudo elliptical jet grouted elements. This geometry is obtained by modulating the rotation speed according to a pre-set pattern.

The system allows to optimize the efficacy of jet grouted elements when the treatment is aimed at constructing a cut-off wall or a retaining wall, ensuring significant time and material savings.

This system can also be used to install cells to prevent sand liquefaction or soil improvement projects.
