Rocksoil S.p.A. researched and developed horizontal jet-grouting systems to improve ground during tunnel advance in ground with poor cohesion, together with similar systems applied vertically for foundation shafts and tunnel portals in unstable slopes, in the second half of the 1980's.

They are currently deemed irreplaceable for working in ground subject to difficult stress-strain conditions if subsidence and undesirable deformation phenomena are not to be triggered.

Special features of these systems include the ability to schedule operations and operational safety.
