What are post-tensioned slabs?

Post-tensioning uses high-strength steel tendons to reduce slab thickness, eliminate unnecessary beams and increase spans. The result is a more efficient concrete structure.

Watch the explainer
Thinner slabsUse less concrete and steel while maintaining performance.
Fewer beamsFlat soffits simplify formwork and reduce floor-to-floor heights.
Longer spansCreate open spaces and give architects more flexibility.

From structural design to on-site execution

We optimise the structure for cost, construction time and performance.

Post-tensioning design

We design slabs using international codes and established structural analysis software to:

  • Reduce slab thickness
  • Eliminate unnecessary beams
  • Increase spans and improve design flexibility
  • Meet safety, durability and code requirements
Efficient designs use fewer materials and leave more usable space.

Materials and accessories

We supply post-tensioning components that meet international specifications:

  • Prestressing steel strands
  • Anchorages and wedges
  • Ducts and accessories
Quality materials improve system durability and reduce maintenance.

On-site execution

Our specialist team carries out the post-tensioning work, including:

  • Tendon layout and installation
  • Stressing operations
  • Quality control and documentation
We keep work moving while maintaining safety and precision.

How we work

A clear path from drawing review to handover of a stressed, documented slab.

Project review

We review architectural and structural drawings and identify the project goals and required spans.

Structural design

We design to international codes and optimise slab thickness and performance.

Material supply

We supply strands, wedges and ducts that meet the project specifications.

Installation and stressing

We install and stress the tendons, inspect the work and document the results.
