Concrete Strengthening

Composites have been used to strengthen structural concrete in the United States for almost 25 years. During this period, acceptance of composites as a mainstream construction material has grown, and so has the number of completed composites strengthening projects. As a result, the use of composites for strengthening and retrofit is gaining more popularity among design professionals over conventional strengthening techniques, such as installation of supplemental structural steel frames and elements.
