A foundation having a wall is stabilized by attaching a bracket to the wall, coupling a jacking apparatus to the bracket, inserting pier sections into the jacking apparatus and driving them with that apparatus, one after the other, through the bracket and into the soil which underlies the foundation, and coupling the pier so formed to the bracket so as to support the foundation through the pier. The bracket has a plate which fits against the wall and is attached to it with bolts and a sleeve which is attached firmly to the plate intermediate the ends of the plate. The pier passes through the sleeve and is connected to the sleeve, once it encounters adequate resistance, so as to support the foundation.
