Reasons to use Post-Tensioned Concrete:

  • Increased clear spans
  • Thinner slabs
  • Lighter structures; reduced floor dead loads
  • Reduced cracking and deflection
  • Reduced storey height
  • Rapid construction
  • Large reduction in conventional reinforcement
  • Higher degree of crack control

Post-tensioned slab systems have been utilised successfully as a primary slab solution for over 50 years, and the Interspan slab post-tensioned system offers versatility and efficiency to all stakeholders in the building process.

Through effective design, post-tensioned slabs enable material and embodied carbon reductions versus a conventionally reinforced slab, while maintaining the inherent benefits of concrete construction.
