SigmaSlab® concrete technology

SigmaSlab - Dramix + CCL PT strands
The SigmaSlab® is a new concrete technology that combines CCL’s post-tensioning strands with Dramix® steel fiber concrete reinforcement. This technology eliminates the need for traditional reinforcement in unbonded, banded-banded post-tensioned concrete slabs, reducing the complexity, time and cost of installation. SigmaSlab® ensures excellent tensile behavior, allowing larger ground slabs with joints that are fewer and farther between.

The advantages of SigmaSlab®

SigmaSlab® combines the benefits of both post-tensioning strands and steel fiber concrete reinforcements. It ensures a robust system, with high crack control while using less steel compared to traditional reinforcement. This results in: 

  • > Reduced maintenance costs 
  • > Optimal crack control 
  • Longer lasting slabs 
  • A lower carbon footprint 
  • More value for money
