Abstract

The patent proposes a new system for treatment of granular and fine incoherent and/or slightly cohesive soils by microinjection into the soils of cementing or impermeabilizing mixtures by means of an appropriate tube. Microinjection of the mixture is preceded by hydrofracturing of the soil with water at high velocity and pressure in order to create preferential paths for the mixture that will be subsequently and immediately injected into the soil, replacing the previously introduced water. <IMAGE>
