  • Patent number: 8911835
    Abstract: The present invention relates to a method for injecting a liquid in a porous material or a material including discontinuity interfaces, wherein said method includes the steps of: attaching an injection part to said material, the injection part defining a compression chamber with at least one surface of said material; injecting said liquid into said compression chamber under a low pressure; and applying a high-power acoustic wave to said liquid using a drawing element, wherein said drawing element extends into said compression chamber.
    Type: Grant

  • Patent number: 5840247
    Abstract: The invention provides a process for the protection of active reinforcements embedded in a concrete mass against the effects of oxidation, said reinforcements being possibly in the form of a bunch of cables or strands arranged in a sheath, providing also the possibility to detect imperfections of the injection grout such as voids or porosity, wherein at least one channel is first drilled in the concrete mass opening in front of the reinforcements which have to be protected, whereafter a corrosion inhibiting solution is injected into the said channel while applying a high power pulsating wave to the said solution to make it penetrate and each channel is occluded.
