Abstract

Apparatus for treating soil by injecting grout into the soil at different levels sequentially, the apparatus comprising a pipe (10) having pistons (19, 20, 21, 22) slidable therein, the pistons being apertured and means extending through the apertures of the pistons longitudinally of the pipe and being movable longitudinally of the pipe to close the apertures of the piston in sequence thus allowing each piston to be moved downwardly by the hydraulic pressure of the grout thus to open apertures (11, 12, 13, 14) in the pipe in sequence and allow grouting at the different levels in sequence.
