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.
