A telescoping pier foundation system comprises generally an outer shell preferably made of a tough and high-strength material, such as, a suitable polymer or a metal alloy, having an internal cavity for receiving a filler material. The outer shell comprises a stationary portion and at least one longitudinally telescoping member in longitudinal alignment with one another and connected to one another to achieve a given height, length or depth for forming a pier foundation. After the telescoping member is adjusted to the height necessary to support a building structural member, a fastener, whose anchor portion extends into the internal cavity of the telescoping member, is secured to the structural member and the internal cavity of the outer shell is filled with the filler material that hardens to form a composite pier foundation.
