Traditional cube crush testing has always been slow, costly, and often inaccurate in reflecting real curing conditions. In today’s construction world, contractors need faster, smarter, and more sustainable ways to track curing performance. That’s where Converge Helix®, a reusable concrete monitoring system, steps in.
For the full overview of how Converge is transforming monitoring technology in Australia, see our main Converge blog.
What is Converge Helix®?
Converge Helix® is a non-embedded, wireless concrete sensor system designed for long-term use across multiple pours. Unlike traditional testing, it measures real-time curing data inside slabs, beams, or tunnels using concrete data sensors connected to the ConcreteDNA® platform.
This system provides contractors with a digital concrete testing alternative, giving instant visibility into temperature, maturity, and strength development without the delays of lab results. By aligning with ASTM C1074, NSW T382, and VicRoads 610-16m standards, Helix® ensures compliance and efficiency in even the most complex projects.
Converge Helix® Product Units
Each unit of the Helix® system plays a key role in delivering real-time results:
- RAK Helix Hub (Wi-Fi & Cellular): Transmits live curing data from sensors with long-range concrete sensor connectivity up to 2km.
- Helix Hub Software: Delivers compliance-ready reports and predictive insights on the ConcreteDNA® platform.
- Helix Node (Hardware): A reusable sensor that captures in-slab curing conditions and strength trends.
- Helix Node Software: Enables communication between the node and hub for accurate analytics.
- Thermal Tails (Single & Multi-Probe): Measure temperature at multiple depths for reliable thermal profiling.
- Calibration Analysis & Report: Links temperature history to compressive strength for mix-specific accuracy.
Together, these components form a concrete temperature monitoring equipment setup that makes quality control easier, faster, and more reliable.

How Converge Helix® Works

The Helix® workflow is simple yet powerful:
- Helix Hub: Set up and install the Helix Hub in a central and elevated position with good visibility. The Helix System now has a means of sending data to ConcreteDNA.
- Thermal Tail: Connect a Thermal Tail to a Helix Node and register the Tail using the ConcreteDNA mobile app and scanning the QR code. Attach the probe to the rebar at your desired measurement point. The embedded probe will send temperature and strength data to the Node.
- Helix Node: Turn on Helix Node and attach it to hoarding or an elevated position outside of the pour, it will transmit data to the Hub and onto ConcreteDNA. Once monitoring of the pour is complete, simply detach the Node from the Tail and reattach to the new desired tail.
- ConcreteDNA Mobile and Web App: Use the ConcreteDNA® app to manually collect data over Bluetooth from the Signal Sensor +™. Concrete strength, temperature, and AI milestone predictions can be view in-real time.
