Abstract
Le procédé selon l'invention se distingue en ce qu'il comporte 'injection d'un agent liquide dans le terrain afin d'augmenter la viscosité de l'eau des pores pour réduire sa vitesse de migration vers une région sujette à la congélation, un exemple d'agent liquide avantageux étant la carboxyméthylcellulose. Le diagramme montre les conditions rencontrées dans le terrain devant être traité. Un tel procédé convient pour réduire le gonflement aussi bien dans le cas d'un terrain sujet à la gélivation naturelle que dans le cas de la congélation artificielle.
