The Latest Composite Technology

The DUCON® Micro-Reinforced Concrete System is a proprietary, innovative system designed for extreme load resistance and energy absorption.

DUCON® Micro-Reinforced Concrete Systems

DUCON® is an innovative, high-performance strengthening and force protection system designed for extreme load resistance and energy absorption. DUCON® combines an infuseable ultra high-performance grout with a densely layered MicroMat® steel reinforcement system. The highly-engineered and test-proven system can be custom-designed to a project’s specific performance requirements.

“Moldable Steel”

Placement characteristics similar to concrete, combined with the ductility and energy absorption properties of steel, give DUCON® “moldable, steel-like” characteristics.

  • Like concrete in placement versatility, DUCON® can be applied to new and existing structural members, or prefabricated off-site to create a wide range of precast shapes and sizes.
  • Like steel with its ductility and energy dissipating qualities, the DUCON® system allows for the highest level of performance for the most challenging applications.
