Abstract The question whether ground freezing by direct gasification of liquid nitrogen (LN2) is an alternative to conventional freezing by circulation of liquid coolants is discussed. Also discussed are: the technical characteristics of and basic differences between the two methods; the specific advantages and disadvantages of ground freezing with LN2; the relevant cost factors and their influence on the overall cost of a freezing project; and the criteria for the technical and economic feasibility of LN2 freezing in construction work. A description is given of four typical applications: for temporary foundations; sealing of a defective diaphragm wall; final sealing of a designed gap in a bored pile retaining wall; and driving of a water tunnel under a railway embankment.
