Patent ID: 7429149

Claim:
A segmented foundation support product comprising: a first support segment and a second support segment, each segment comprising: a cylindrical, tubular sleeve, the sleeve having a cylinder axis, a front opening, and a rear opening; a non-metal substantially cylindrical plug, the plug being coaxial to the cylinder axis; the plug extending axially from a transverse interior plug face within the sleeve to a transverse exterior plug face beyond the sleeve; the interior plug face being positioned inside the sleeve medial the front opening and the rear opening; the exterior plug face being positioned outside the sleeve distal the front opening; the plug substantially filling the sleeve between the interior plug face and the front opening; the plug forming a plug projection between the front opening and the exterior plug face; the plug and the sleeve forming a cavity within the sleeve between the interior plug face and the rear opening; the plug being bonded securely to the sleeve; the segments, in use, being assembled together with a plug projection inserted telescopically into a cavity so that the first segment plug contacts the second segment plug and so that the first segment sleeve is wholly spaced apart from the second segment sleeve; and the projection and the cavity fitting together so that the assembled segments cannot substantially move radially with respect to each other.
