Usually the injection pressures wil

Usually the injection pressures will be of the order of 1 to 3 MPa, only greater pressures being acceptable in special cases duly accompanied by the inspection.

For a land and a given grout, the pressure is controlled by the injection rate, which can be easily regulated. It should not be too weak to affect the performance of the work, nor too strong, so that the pressure on the ground is not exceeded (in order to avoid billing and cracking of the ground) or affect surrounding buildings
