Digging a well, restoring the foundations of a building or digging a tunnel in the soils of big cities constitute difficult projects due to a large number of already existing pipelines and sewers. When the city has a clayey subsoil with some content of water and highly permeable sandy lenses, risks of settlement, water leaks, or erosion necessitate the employment of special expensive construction methods. The National Autonomous University of Mexico developed an accelerated soil freezing process for use in emergency work involving the direct injection of liquid nitrogen through the ground to be stabilized. This article presents the principal results obtained by this method as well as considerations of an economic nature on the applicability of the technique as well as a comparison with other conventional-type freezing methods.
