How SmartRock Helps

Forget about waiting for break test results. With consistent real-time data, never have project delays by knowing when to remove formwork and move on to the next floor as early as possible.
Buildings & High Rise Projects
Buildings & High Rise Projects
Whether you are doing accelerated bridge construction or UHPC joint fillings, avoid unnecessary costs and delays associated with testing labs and wired loggers with accurate, real-time data and gain more insights into the strength of your concrete than ever before.
Bridge Construction
Bridge Construction
Closely monitor temperature differentials between the core and edge of your mass pours with SmartRock's dual temperature capability. Get alerts on temperature differential thresholds with Giatec 360 and follow your thermal control and curing plan without any of the hassle of cumbersome wired sensors, loggers, and thermocouples.
Mass Concrete Pours
Mass Concrete Pours
Accepted by the majority of DOTs, collect temperature and strength data right on your mobile device and in remote areas using SmartRock sensors and the SmartHub device. With updates every 15 minutes, prevent delays and open roads to traffic earlier.
Highways, Roads, & Concrete Pavement
Highways, Roads, & Concrete Pavement
To prevent cracking and unnecessary delays timing is everything when pulling cables in post-tensioned concrete elements. As the most accurate method of measuring concrete strength onsite, the maturity method will eliminate your reliance on field-cured break tests, so you know right away when your concrete is ready for tensioning.

FAQs

The design of the SmartRock 3 sensor enables measuring temperature values at two locations simultaneously, one at the temperature probe (tip of the white cable) and one in the body of the sensor (black transmitter). The result can be visualized on the SmartRock Mobile App or the Giatec 360, a Cloud-Based Project Dashboard, where the measurements are differentiated through the “Cable” and “Body” designation.

The design of the SmartRock 3 sensor enables measuring temperature at the tip of the white cable (temperature probe) and on the body of the sensor (the black transmitter). On the sensor page of the SmartRock application or the Giatec 360 platform, users can toggle between the two temperature values identified as “cable” and “body” at the top of the page. The temperature graph will display both temperature profiles and will highlight the difference between the measurement points.

The sensor transmitter must be installed no more than 2 inches (5 cm) from the concrete surface. This is to enable strong wireless signal strength for continued connectivity to the sensor, even long after it has been installed in concrete.

When the SmartRock sensor is installed inside concrete as recommended, it can transmit up to 40 ft (12 m). When the black transmitter is exposed, the range of the wireless signal can be up to 100 ft (30 m).  Longer connection range can be obtained with the SmartRock-Long Range in conjunction with the SmartHub-Long Range with which data can be transmitted for up to (300m) when the body of the sensor is embedded at recommended depth and up to 1000ft (800m)  when the body is placed outside the concrete.

The sensor takes a measurement every 15 minutes, allowing it to collect data for 2 months. However, the battery life extends for up to 4 months. This enables the user to retrieve the data for an extra 2 months once the memory is full.

Yes. The sensors can be turned off to preserve battery and memory until the start of the pour, this is done by inserting the temperature probe back into the sensor body.

Yes. Please ask for customized length options when you are ordering your SmartRock package. 

The SmartRock 3 is available in two different lengths; the shorter cable has a length of 12 in (30 cm), while the longer cable can measure concrete temperature up to 10 ft (3 m) inside your concrete structure. By request, we also offer 50 ft (15.2 m). Contact our team if you are not sure what sensor would be the best suited for your application.

The QR code on the SmartRock 3 sensor is a feature for tagging sensors on the mobile application. The application will guide you through adding new sensors to your projects. To do so, the application will prompt you to scan the QR code on the sensor.

Anytime the temperature probe (the white cable) is removed from the sensor, this activates the sensor. The LED light located on top of the sensor body will blink 3 times to indicate that the sensor was properly activated and is ready to be used.

The SmartRock 3 has three main physical components, the white cable, the sensor body, and a rubber installation strap. The activation and installation procedure was enhanced from 2 metal wires that were twisted around the rebar in the SmartRock 2 generation, to a rubber strap meant to tightly install and secure the sensor. The installation strap was specially designed to install the sensors on different sizes and types of rebar. It can also withstand 40 lbs of force.

  • The SmartRock 2 sensor was activated by twisting the two metal wires together. However, in the SmartRock 3, the sensor is activated by pulling the white cable out of the sensor transmitter (sensor body).
  • The SmartRock 3 sensor can now be tagged much more rapidly and easily using the QR code located on the top of the sensor and the SmartRock app.
  • With the SmartRock 3, temperature can be measured at two locations: at the tip of the white cable and in the transmitter, with a measuring range of -22˚F (-32˚C) to 181˚F (85˚C).
  • The green LED light on the SmartRock 3 body blinks 3 times whenever the sensor is activated, providing the end user a visual an indication that the sensor is fully functional and ready to be used.
  • The SmartRock 3 has an increased wireless signal range of up to 40 ft (12 m) when installed in concrete.

The SmartRock – Long Range has an additional wireless communication capability compared to the SmartRock. This means it can be used in the exact same way as the SmartRock with the addition of long-range capabilities for remote monitoring with the SmartHub – Long Range.

Only SmartRock – Long Range sensors are compatible with the SmartHub – Long Range.  Remote monitoring with SmartRock requires the SmartHub.

Yes, both the SmartRock and SmartRock – Long Range collect data every 15 minutes for two months. It is also possible to connect to the sensors and collect stored data from up to 4 months (for the duration of its battery life).
