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.
