Post-tensioning has revolutionised the design and construction of concrete structures, allowing thinner concrete sections, longer spans and more durable concrete structures. It also paved the way for the development of new construction methods, making bridge construction simpler, faster and more cost-effective.
The technique was patented by Eugène Freyssinet in 1928. It was developed on thousands of structures across the world by the STUP (Société Technique pour l’Utilisation de la Précontrainte), the company created by Eugène Freyssinet in 1943 – that became Freyssinet in 1976. Post-tensioning is now universally known and widely used.
