Abstract: 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.

Abstract: A hydraulic self contained foundation leveling shim is provided and placed in the upper end of a poured concrete foundation leveling pier before curing. Hydraulic hoses lead to the surface to allow hydraulic fluid to be pumped into and removed from the hydraulic chamber of the shim to raise or lower the foundation on the pier. A plurality of the piers and shims is used to level the foundation of a structure that has settled in unstable soil.

Abstract: An artificial ski surface construction includes a support surface having an energy absorbing base of elastomer thereon. A flexible sheath covers the energy absorbing base and includes a continuous surface having a fabric underside to contact the sheath with fibers extending upwardly therefrom to provide an artificial ski surface. A structure positions the support surface to form a slope and the continuous surface forms an endless belt which is mounted on rollers with motor means to rotate the rollers and move the continuous surface relative to the sheath and elastomer base.
