Support that answers at 3am. 

Real support during live placements. It's one of the biggest reasons teams switch to Converge – and stay.

Why Contractors Choose Converge

Program certainty without the guesswork

Every pour that waits on cylinders is programme time lost. Converge gives your team live in-situ strength data so you strip, stress, and sequence the next activity the moment the concrete is ready — not when the lab eventually calls back.

Up to 40% faster formwork striking

Recover 1 in 5 working days on concrete-critical projects

Earlier decisions without compromising QA

Thermal compliance without the manual overhead

On large pours, tracking temperature differentials manually isn't just painful, it's a liability. Converge monitors automatically, flags exceedances early, and maintains the full thermal record for you.

ASTM C1074 compliant

Automated alerts, no overnight checks

No manual thermocouple logs

Decisions you can defend

When someone asks why you struck that formwork, you have data — not opinion. Converge gives your team a continuous in-situ record showing exactly how the concrete performed and when: strength, temperature, pour history, and QA traceability, all in one place.

Every decision documented.

Every pour traceable.

Every formwork call defensible.

Signal Sensor™

Frequently Asked Questions

How deep should the sensor be installed?

We recommend installing the Converge Signal sensor up to 100mm below the concrete surface, and making sure the face with the QR code is facing up.

What range of wireless connection should I expect from the sensor?

Once in concrete, the sensor range could be up to 8m, depending on the rebar configuration around the sensor and the sensor installation depth. Please ensure that you are closer than 8m and the Converge app is on your phone screen (not background) when communicating with the device.

Can I collect measurements when my phone is not connected to WiFi or data?

If you can't access the internet where the sensors are placed, the mobile app will download the measurements over Bluetooth and store them locally on the phone. But make sure to connect your phone to WiFi or mobile data, as soon as you can. Then, open the Converge app to upload the stored measurements

How long do I need to wait to collect all the data from a Signal sensor?

The app takes about a minute per day of sensor readings/data. For example, if the last collection was done on Monday, and then you go to collect data again on Thursday, there will be three days of data to be collected on the device. This data collection will take around 2 minutes or less.

Signal Live Hub™

Frequently Asked Questions

What is the difference between the Signal sensor system and the Helix sensor system?

The Signal sensor system is a fully embedded concrete monitoring solution with a wireless communication range of up to 15m or 50ft. The Helix sensor system is a non-embedded and reusable system with a longer range of up to 1.3km or 0.8miles.

Will I lose temperature measurements if the Signal Live Hub loses connection with the Signal devices or stops transmitting data?

If the Signal Live Hub loses connection with the Signal devices or if the hub goes offline, it will collect historic data and transmit it when it regains connection, ensuring that no data is lost. Users can also manually collect data with the ConcreteDNA App on their smartphone at any time.

Is the Signal Live hub available worldwide?

The Signal Live hub is currently available in UK, EU, US, Canada, Australia and NZ, Singapore, Hong Kong and India.

What range of wireless connection to the Signal devices should I expect from the hub?

When in concrete, the Signal Live Hub will be able to detect Signal devices up to 15m or 50ft away, depending on the rebar configuration around the device and the site environment in which it is in, e.g. number of obstructions between the hub and the Signal devices.
