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.


FERROCK  UPDATE – February 2018.  

We have seen tremendous interest and inquiries for additional information and samples.  The most recent activity entailing the US Grant Project in Arizona featuring this material Ferrock, has now concluded and with that we enter the next phase:  The Ferrock effort is actively seeking a Venture Equity Investment. 

In order to proceed with the further definition of this material as a viable and commercial building material, an investment partner with not only financial resources but also knowledge of the building and construction industry is Required.   The next phase will include detailed raw material sourcing design, aggregate material options, CO2 curing methods for in-situ and factory environments, as well as target market definition and comparative cost analysis.  The financial and production capabilities of  such partner(s) will drive the duration of this cproduct commercialization phase but is generally expected to last 18 – 24 months.  We would be glad to discuss this opportunity with suitably interested parties.  

While we have many requests for technical information, Ferrock ‘kits’ and sample materials, we are unable to reply and respond to such requests int he larger interest of growing this properly to the next phase.  This is a small operation that needs to partner in order to grow so, the opportunity to join us at an early stage and help drive the development is ideal!

Please reach out to us if this is of interest.

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

David Stone, inventor of Ferrocrete, gives a brief overview of this new, eco-friendly substitute for Portland cement.
