The jet grouting technique consists in the injection of cement grout at high pressure (up to 600 bar) in the ground after vertical drilling with the same kind of technology used for micropiles and tie rods. Using a monofluid it is possible to obtain piles with a diameter varying from 40 to 100 cm. Using a bifluid (that is combined with high pressure air that allows the penetration of the mixture into the interstices of the soil) it is possible to reach diameters up to 2 mt.

Jet grouting is used in a wide range of applications: from tank plugs, underground parking areas in presence of groundwater, bulkheads for waterproofing river embankments, to the improvement of mechanical and load bearing soil conditions.
