20080205995 | Method For Saturating Cavities Present in a Mass of Soil or In a Body in General - A method for saturating cavities present in a mass of soil or in a body in general, comprising at least one step for at least partial filling of the cavity by introducing into the cavity a filler material in the solid state or in the fluid state and capable of setting. At least one step of saturating the cavity is then performed by introducing into the cavity a fluid synthetic substance which expands and sets by chemical reaction. The synthetic substance is adapted to generate, as a consequence of its expansion, at least the saturation of the cavity and a compaction and/or loading of the filler material introduced into the cavity in the filling step, creating an optional state of permanent tension on the walls that delimit the cavity, to the point of producing, if necessary, a deformation of the walls. | 08-28-2008 |

20120207552 | SUBMERGED VOID FILLNG - Systems and methods for filling submerged voids with a foam-fluidized fill material in an efficient and economical manner are disclosed herein. The foam fluidized fill material is a granular solid material fluidized with a foam. The foam-fluidized fill material is pumped or gravity-fed through an insertion tube into the submerged void. The insertion tube terminates at a point lying below a surface of the liquid within the void. Since the foam-fluidized fill material is heavier than the liquid, the foam-fluidized fill material exiting the insertion tube sinks to the bottom of the void and expands laterally at the bottom of the void displacing the liquid. The liquid is forced upward and out of the void where it may be collected. Further, as the fill material fills the void, the foam dissipates and the fill material self compacts, making the filled void sufficiently load bearing. | 08-16-2012 |
