A system and method for heating concrete structures to either prevent the build-up of freezing precipitation or eliminate freezing precipitation on a top surface of the concrete structures. The system includes a heating assembly integrally formed with a concrete structure to apply thermal energy to the top surface of the concrete structure. Optionally, the heating assembly includes heating elements formed of carbon fiber tape. Following formation of the concrete structure, the heating assembly is configured for unified movement with the concrete structure. The system optionally includes a control assembly operatively coupled to the heating assembly. The control assembly selectively powers the heating assembly and can be configured for remote operation. In use, the control assembly can be selectively activated from a remote location to power the heating assembly and heat the concrete structure.
