Post-tensioning is a technique used to strengthen concrete structures by applying internal forces to compress the concrete after it has hardened. This process helps to counteract tensile stresses that may occur due to bending or external loads. By introducing pre-stress into the structure, post-tensioning increases its ability to resist deformation and cracking under load. This technique is particularly effective in bridges, parking structures, and buildings with long spans, where minimising deflection and enhancing durability are critical for maintaining structural stability and performance.
