JET GROUTING GOES TO GROUND

The technique of jet grouting, a method of excavating and filling below the surface, is being used for the first time in the UK in the restoration of a railway tunnel. The technique may be used in all soil types as a means of providing a simple and flexible control for sub-surface fluids and solidifying unstable ground. Jet grouting is an alternative to conventional grouting and offers advantages over chemical grouting, deep slurry trenching and compressed air or ground freezing techniques. Jet grouting is achieved by the use of a high pressure air and water jet in a pre-bored hole. Spoil is brought to the surface by air-lift pressure and the void so created is simultaneously re-filled with grout. (TRRL)
