ABSTRACT:
A piering member includes a generally tubular body that has a flarable end so that when the piering member is inserted into the ground, the flarable end of the piering member can be flared outward to increase the area of support for the foundation that rests upon the piering members. The flarable pier includes slits formed in the body to allow a flaring member to force the segments of body, formed by the slits, outward. The flaring member may be inserted from the top of the piering member or may include a conically shaped flaring member inserted into the bottom of the pier.
