An in-ground lifting system and method are provided that is operable for raising
a structure and its foundation at least several feet. In one presently preferred
embodiment, the method is utilized to raise the structure above any anticipated
flood levels to thereby prevent future flooding of the structure. In a preferred
embodiment, a plurality of excavations are formed underneath the foundation, such
as with a hydro-excavator. A sleeve with seal members and hydraulic lines is installed
and aligned within each excavation. Hardenable material is poured outside the sleeve
to form a cylinder. Hardenable material is poured inside the sleeve to form a piston.
Fluid is pumped through the hydraulic lines to lift the structure and the foundation.
