Post tensioning

Post tensioning is a technique for reinforcing or supporting structures. Post-tensioning tendons, which are prestressing steel cables or bar (tendon) inside plastic ducts or sleeves, are positioned within the structure. Prior to service loads being applied to the structure, the tendon is tensioned and anchored against the surface of the structure.

Common forms and applications for post tensioning include:

  • Slab and foundation post tensioning
  • Multistrand Post tensioning - ideal for longitudional post-tensioning of bridges, building frames, containments, special structures.
  • External Post-Tensioning - ideal for strengthening existing structures, utilising external tendons which are easy to inspect or replace.
