A system for soil consolidation is disclosed. It comprises: a delivery channel (10) that is closed at one end and adapted to receive a grout or resinous liquid (99). The delivery channel (10) has a plurality of apertures (20) that are selectively openable and closable, ideally by way of a concentric member (40) in order to permit filler or resinous material (99) to exude/egress from the delivery channel (10) into selected regions of surrounding soil at desired times, in a controllable manner, so as to create a stabilized volume of soil bonded to the delivery channel. ## Claims ### Claim 1 A ground stabilization system, suitable for soil consolidation, includes: a delivery channel that is closed at one end and adapted to receive a grout or resinous material, the delivery channel having at least one chamber, there being at least one valve defining the at least one chamber and apertures formed in the delivery channel wall; wherein the delivery channel is adapted to receive a concentric member, which in use passes through the at least one valve, the concentric member being displaceable with respect to the delivery channel such that the at least one valve is selectively opened and closed to permit at least one of grout and resinous material to fill a selected one of said at least one chamber and exude via the selected apertures, into regions of surrounding soil to create a stabilized volume of soil bonded to the delivery channel; and wherein the at least one valve is configured such that removal of the concentric member from the at least one valve acts to close the at least one valve, thereby sealing the at least one chamber. ### Claim 2 (depends on 1) The system as claimed in claim 1 wherein the concentric member is a hose or duct. ### Claim 3 (depends on 1) The system as claimed in claim 1 wherein non-return valves are defined in the delivery channel by way of a narrowing annulus. ### Claim 4 (depends on 3) The system as claimed in claim 3 wherein the narrowing annulus is held in position in the delivery channel by a connector which passes through the wall of the delivery channel. ### Claim 5 (depends on 1) The system as claimed in claim 1, further comprising: means for pressurizing the at least one of grout and resinous material in the delivery channel. ### Claim 6 (depends on 1) The system as claimed in claim 1 wherein the channel includes an integral tip at the distal end. ### Claim 7 (depends on 6) The system as claimed in claim 6 wherein the distal tip is formed from one of case hardened steel and tungsten carbide. ### Claim 8 (depends on 6) The system as claimed in claim 6 wherein the distal tip is tethered to an internal cable. ### Claim 9 (depends on 1) The system as claimed in claim 1 wherein a diameter of the apertures formed in the delivery channel wall are in a range of 0.003 m to 0.01 m. ### Claim 10 (depends on 1) The system as claimed in claim 1 wherein the diameter of the delivery channel is in the range of 0.01 m to 0.1 m. ### Claim 11 (depends on 1) The system as claimed in claim 1 wherein the delivery channel is formed from a plurality of inter-engaging sections. ### Claim 12 (depends on 11) The system as claimed in claim 11 wherein the inter-engaging sections are joined by way of threaded end sections. ### Claim 13 (depends on 1) The system according to claim 1 wherein the apertures are tapered and/or rifled to limit clogging. ### Claim 14 (depends on 1) The system according to claim 1 wherein the delivery channel is adapted to accept an end cap. ### Claim 15 A method for soil consolidation comprising the steps of: driving a delivery channel into ground to be consolidated, the delivery channel being closed at one end and adapted to receive at least one of grout and resinous material, and having at least one internal valve that separates one chamber from an adjacent chamber; filling the delivery channel with the at least one of grout and resinous material via a displaceable concentric member; and withdrawing the displaceable concentric member to allow the at least one of grout and resinous material to enter a cavity so that the at least one of grout and resinous material exudes via a selected aperture from the delivery channel into selected regions of surrounding soil, so as to form an agglomerated mass of soil and grout or resinous material which adheres to the delivery channel. ### Claim 16 (depends on 15) The method for soil consolidation as claimed in claim 15 comprising the steps of: controlling egression of the at least one of grout and resinous material selectively from a chamber defined in the delivery channel into selected regions of surrounding soil.
