Post-tensioning techniques consist of the installation of tensile elements within or along concrete structures. This process applies an assortment of stresses in a way which counteracts the tensile stresses that the concrete may experience over its service life. As a result, this technique helps to reduce or eliminate deformation and cracking in the concrete.

Revolutionizing Construction
Post-tensioning has transformed the design and construction of concrete structures, enabling the use of thinner concrete sections, longer spans, and more durable buildings that would otherwise be impossible due to site constraints or architectural requirements. This technique has also led to the development of new construction methods, making bridge construction simpler, faster, and more cost-effective.
This innovative technique was patented by Eugène Freyssinet in 1928. It was further developed on thousands of structures around the world by the STUP (Société Technique pour l’Utilisation de la Précontrainte), a company founded by Eugène Freyssinet in 1943, which was renamed Freyssinet in 1976. Today, post-tensioning is universally recognized and widely used.
Post-tensioning unlocks greater architectural freedom, enabling innovative designs with complex curves, varying elevations, and long, unobstructed spans. This technique allows for sleek, modern structures that would be difficult or impossible to achieve with conventional concrete construction.
Post-tensioning minimizes material usage by reducing the amount of concrete and steel needed for both structures and foundations. It also streamlines construction by enabling the rapid assembly of precast elements through industrialized methods, accelerating project timelines and improving overall efficiency.
Post-tensioning minimizes the need for joints, significantly reducing maintenance requirements over time. In structures like tanks, silos, and reservoirs, it creates nearly crack-free concrete, providing superior resistance to corrosion and extending the lifespan of the structure.
Post-tensioned structures use fewer materials, reducing the need for steel reinforcement and concrete. This results in lower greenhouse gas emissions from production and transportation, with carbon savings typically ranging between 20% and 30%.
