Installing, inspecting and repairing the tendons that hold modern long-span structures together.
Post-tensioning threads high-strength steel tendons through ducts cast into concrete, then stresses and anchors them so the concrete is squeezed into permanent compression - the trick behind thin long-span floor slabs, segmental bridges, containment tanks and ground anchors. The specialist sector covers new installation, and the growing business of investigating, de-tensioning and repairing systems in ageing structures.

Post-Tensioning Systems in depth
About Post-Tensioning Systems
It is licence-to-operate work: stressing operations put lethal energy into a strand, grouting quality decides whether tendons last a century or corrode unseen, and cutting into a PT slab without knowing where the tendons run is one of the fastest ways to put a project on the front page.
