Abstract (en)

[origin: WO8905887A1] In the process described, a liquid (A) containing water glass is introduced into the soil to be treated and possibly reacted with another liquid (B) introduced into the soil, in order to form a hydrogel. The process is characterized in that liquid (A) is treated, before or during its introduction into the soil to be treated, with an aqueous suspension of a hydraulic binder (liquid C).

Abstract (fr)

Au cours du procédé décrit, on introduit dans le sol à traiter un liquide (A) contenant du verre soluble, que l'on fait réagir avec un liquide (B) également introduit dans le sol, afin de former un hydrogel. Ce procédé est caractérisé en ce qu'avant ou pendant l'introduction du liquide (A) dans le sol à traiter, ce dernier est traité avec la suspension aqueuse d'un liant hydraulique (liquide C).
