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 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.
