IronKast has engineered a new patented concrete technology based on iron carbonate that uses a majority of recycled materials to create a Less Expensive, Stronger, More Flexible and Carbon Negative concrete that grows stronger in salt water environments.


Ironkast is currently finishing work on a grant and anticipates completion in the late months of 2017.  It is considering funding and partnership opportunities required for the next phase of commercializing the process, patent, technology and market applications.

Meet Ferrock™

IronKastPour2IronKast is in the early stages of commercializing the patent for its “Ferrock™” product with a focus on pilot implementations in marine environment applications with the goal being to certify for widespread use the preliminary mixtures and techniques already tested and benchmarked by the University of Arizona.

The potential for Ferrock™ is as a widely used green, alternative building material that could be made from over 95% recycled material.

Ferrock™, which posesses significantly greater flex characteristics and immunity from many of the chemicals and reactions that break down normal concrete in salt water or waste water environments, is ideally suited for environments where traditional concrete is vulnerable.

Ferrock™ is ideal for:

  • Structures in salt water or marine environments
  • Seismically active areas where foundations are subject to displacement
  • Material conveyance systems such as water and waste pipes
