Screw-shaped reinforcements that you mix right into concrete, Helix® Micro Rebar™ is stronger, more durable, and more flexible than rebar, and saves you time and money.

Proactive Concrete Reinforcement Technology

Helix® Micro Rebar™ reinforcement increases concrete’s strength and resilience and eliminates or reduces the traditional reinforcement (rebar and mesh) required by building codes.

Helix® Micro Rebar™ concrete reinforcement is added at the ready-mix plant or on site directly to the concrete mix, reducing costs and valuable time. Clients say they save one day of construction for every 10,000 square feet of rebar they replace with Helix® Micro Rebar™ reinforcement.

Our technology spans a wide range of market segments, including Commercial, Industrial, Residential, Precast, Infrastructure and ICF.

Proven in the Field

From slabs, walls and footings to foundations and infrastructure projects, over the past two decades, Helix Micro Rebar™ has been used in thousands of projects and applications, and been shown to improve resiliency, ductility, and strength of concrete structures.

Save Time

Every 10,000 sq. ft. of rebar replaced with Micro Rebar™ saves one full day of construction.

Save Money

Using Micro Rebar™ allows contractors to simplify operations, dramatically reducing project costs.  

Stand Out

Micro Rebar™ doesn’t doesn’t just meet code and reduce project costs, it’s also easier to use than rebar and mesh—allowing engineers to set themselves apart with clients.

Proven for 20 Years

After two decades, more than 100 million square feet of slabs and more than 20,000 vertical structures, the results speak for themselves.

Increases Strength

When compared to Rebar, Helix Micro Rebar™ can increase fatigue resistance by up to 300% and the flexural strength by up to 33%.

3rd Party Accredited

Micro Rebar™ has been certified by the International Code Council Evaluation Service (ICC-ES) and Uniform Evaluation Service (IAPMO-ES).

Because it locks into the concrete, Micro Rebar™ increases the amount of force that would be required to crack it. It would actually have to untwist to pull apart, which is a completely new failure mechanism that makes Micro Rebar™ better than other options.

Specify Helix

Helix® Micro Rebar™ Reinforcement Three Part Specification

Specifying Helix® steel reinforcement is simple. Here you will find the necessary CSI formatted specification template. Also available are partially completed substitution forms for during the bidding process and after. Add Helix® reinforcement to the drawings in a note, do not remove the original design. This gives the contractor and building official the opportunity to choose.

The note should say: “use the original reinforcement shown in the drawing or Helix® 5-25 at x lb/yd3 designed and installed in accordance with UES ER 0279 or ICC-ES ER 3949″.  We recommend also indicating that the manufacturer should have at least 10 years experience manufacturing and requiring that the manufacturer also have ISO 9001 Certified Quality Management System.
