Abstract
A method for freezing and treating a mass of soil, making it possible to compensate for deformations of the mass of soil during thawing, including the following steps: a) producing at least one bore (2) in the mass of soil, b) at least partly freezing the mass of soil using a freezing fluid injected into the bore, and then c) injecting a compensation grouting into the mass of soil, using the bore (2) that was used for freezing, during the thawing phase in order to at least partly compensate for variations in the volume of the mass of soil when the latter thaws.
