Note: Helix® Micro Rebar™ reinforcement must be approved by the engineer of record and/or building official prior to construction in accordance with allowances in the code (e.g. IBC/IRC 104.11). The Helix Steel engineering team provides full support of this process. Contact us for design assistance and approvals.
Dry Mix Procedure
See how to add Helix to a dry batch (the concrete materials are added dry into the truck and the truck does the mixing) ready mix plant.
Central Mix Procedure
Instructions on how to add Helix to a central/wet mix plant (the concrete is premixed in by they plant and discharged into trucks after mixing is complete).
On Site Batching
Not able to add Helix at the plant? No Problem! Stop before adding whole boxes at a time and review these instructions for proven methods of adding Helix successfully at the jobsite.
Prevent common issues by following detailing best practices. See how to properly detail penetrations, reentrant corners, dock walls and other critical areas.
Slab Subgrade Preparation
Restraint and settlement are some of the most common root causes of issues with slabs on grade – review this with your excavation contractor prior to pouring your slab.
Lean about the pros and cons of using a moisture membrane in slabs and pavements.
Direct Concrete Discharge
One of the big benefits of using Helix is that because there is no rebar and/or mesh in the way you can drive trucks right up to the pour, no need for pumps or belts (and the cost that comes with them).
Pumping and Conveying
Still need to pump or convey, Helix is fully compatible. Follow these best practices.
Consolidating or Vibrating
Use normal concrete best practices for consolidating and Vibrating with Helix.
The screeding process helps to force the Helix and aggregates below the surface. Make sure that the screed engages the concrete in its auger for best results.
Look for paste development at the surface. This is an indication the Helix is being forced down below the surface with this operation. Contractors report that Helix is much easier to float than fibers.
Helix is fully compatible with hard trowel operations, take a look at this video for some best practices.
Form Finishes — Poured Walls and Precast
Helix will finish smooth against forms without protruding. Be sure to make sure form edges are clean an free of damage.
Helix will not stick up even with broom finishes. Be sure to review these best practices. Proper timing and brooming in one direction only are the most important considerations
Similar to form finishes, Helix works well with concrete stamps. Follow normal best practices for stamping.
Saw Cutting — Wet and Dry Methods
Helix cuts cleanly due to its screw shaped threading. Review our best practices for early entry and wet cutting.
Shrinkage and curling are issues can be avoided with proper curing. Helix requires no special curing practices, but review this video for general curing best practices
Looking for an cool architectural finish – salt and pepper with silver sparkles? We can provide this with Helix, but this video is a must view for those interested in polished finishes with Helix.
