Abstract: An axial reinforcement system is disclosed that provides a shell (i.e., a form or jacket) that protects a weight-bearing member (e.g., a cement column) from a corrosive environment and which also substantially increases the structural capacity of the weight-bearing member. The shell is integrated with “positioners” and reinforcing elements, the combination of which offers several advantages over conventional shells. The positioner is attached directly to the shell and the positioner is, in turn, secured to a reinforcing element, which can be a reinforced steel, such as rebar, or a carbon fiber reinforced polymer material. The axial reinforcement system has been found to substantially increase the structural rigidity of the weight-bearing member, while at the same time protecting the weight-bearing member from corrosion and is also simple to install.

A radial surface of the shoe causes compressive forces on the material at the bottom of the hole and blades on the radial surface when reciprocated back and forth by the tube cause break up of the compressed material to allow repeated compression and significantly increased supported loads on a pile which is applied with the tube removed and is supported on the shoe.
