An injection lance 100 for permeation grouting, the injection lance comprising one or more stages 150 with each stage comprising: a tube 160 defining a longitudinal conduit 162; a plurality of first apertures 165 through the tube, a resiliently deformable sleeve 170 fitted onto the exterior of the tube, and a plurality of second apertures 175 (e.g. slits) through the sleeve. Preferably the sleeve is tight around the tube when no internal pressure is applied to the sleeve and preferably the second apertures are closed when the pressure within the sleeve is below a threshold pressure. Preferably the second apertures expand as pressure inside the sleeve increases.
