<p>A method for consolidating soils by injecting into the soil a bicomponent resin, derived from a reaction between polyols and isocynate, includes continuous alternating injection of at least two resins A and B which exhibit different nominal densities, alternation between the injected resins being a function of a variation of injection pressure, and/or of a flow rate of the injected resin through a nozzle.</p> |
