Helix Micro Rebar was originally developed by engineers at University of Michigan in response to a request from the U.S. military. In the early 2000s, with conflicts in the Middle East and the threat of terrorism at home, the U.S. Army Corp of Engineers needed a more blast-resistant concrete. In response, UM researchers created Helix, a twisted steel micro rebar technology that replaces most rebar and creates a concrete that is stronger and less resistant to cracking.
For nearly two decades, Helix has enhanced the performance of flatwork, slabs, foundations, tunnels, and a wide range of above-grade applications. Now, after years of real-world testing in the most demanding applications around the world, Helix is available for your construction project.
How it Works
Because of its patented twisted shape, Helix bonds tenaciously with the concrete matrix and is anchored securely into place. Made from high tensile steel, it’s exceptionally high modulus of rupture stops concrete cracking at the microscopic level. Unlike rebar, mesh and fibers, Helix works before the concrete fails. It is the only reinforcement approved to replace structural reinforcement in concrete with a simple design method.
Helix Twisted Steel Micro Rebar can be added at the jobsite or at the batch plant for convenience and precision, and can be pumped just like traditional mix designs.
The product is available in two different grades. Helix 5-25 is a code-approved corrosion-resistant product with nearly two decades of proven success in structural applications. Helix 8-50 is intended to replace other types of fiber reinforcement in industrial slabs and underground works. Both products increase the modulus of elasticity and tensile strength of the concrete.
