ABSTRACT:
A pier adapted to support a load such as a foundation wall comprises a concrete pillar, a support tube oriented substantially perpendicular to and on top of the pier, a pair of threaded rods embedded in the pillar and extending through the support tube, and four threadably mounted on the threaded rods to secure the support tube to the pier. A portion of the support tube extends beyond the periphery of the pillar and is disposed below the load, whereby the load is supported by the extending portion of the support tube. A slippery, plastic liner surrounds the upper portion of the concrete pillar so that swelling of soil surrounding the liner is inhibited by the liner from displacing the concrete pillar.
