Abstract: An adjustable pier system that allows the elevation of a building structure to be readily adjusted when soil subsidence occurs. The adjustable pier includes telescopically intercoupled upper and lower members. The lower member is coupled to a grade beam or spread footing, while the upper member is coupled to a sill beam of the structure. When the elevation of the structure is adjusted upwardly, the adjustable pier is automatically extended. After extension, a mechanical stop can be inserted between the upper and lower members to prevent retraction of the adjustable pier.

Abstract: A pavement system utilizing a plurality of individual pavement segments. The elevation of the individual pavement segments can be adjusted by pumping a flowable material below the pavement segments through preformed ports in the pavement segments.
