Abstract
A method and apparatus for installing remedial piers in which substantially vertical piers are located in close proximity to the wall and footing of an existing structure and are drilled to a substantial depth to penetrate a rock stratum or debris-laden soil. The piers support the structure upon eccentric brackets to transfer the structural load from the footing to the piles. Installation of the piers is followed by a continuous lift of the structure via hydraulic manifold.
