Post Tensioning

Post Tensioning is a technique used to strengthen concrete structures by tensioning steel tendons after the concrete has hardened. This method improves load-bearing capacity, reduces cracking, and enhances the overall durability and structural performance of the concrete. Widely used in bridges, flyovers, and high-rise buildings, post tensioning offers design flexibility with longer spans and thinner slabs. It also reduces material consumption and construction costs. The technique uses anchorages, jacks, and wedges for stressing operations, and is applicable in both bonded and unbonded systems. Post tensioning is a modern construction method that contributes to resilient infrastructure.
