Real-time temperature and maturity monitoring of concrete

SmartRock™ is a rugged waterproof wireless sensor that allows real-time temperature and maturity monitoring of concrete. The sensor is placed in the concrete formwork (installed on the rebar) before pouring. Using the SmartRock™ app you can view the temperature and resulting concrete strength in real-time.

SmartRock™ can be easily placed in the concrete formwork (installed on the rebar) before pouring to monitor the in-situ temperature and maturity of concrete according to ASTM C1074. The continuous measurements are recorded on the SmartRock™ memory and can be downloaded and analyzed onsite at any time during the concrete setting and hardening using the free Android/iOS mobile apps on a smartphone or tablet device.



Optimise formwork removal

With the continuous concrete temperature monitoring of the SmartRock sensor, concrete strength and maturity is automatically calculated. This allows you to more efficiently schedule construction operations such as formwork removal, saving you time and money.



Reduce labour costs

The hassle of connecting to wired data loggers are a thing of the past. With the wireless abilities of the SmartRock sensor, any colleague with a smartphone can visit site and instantly share concrete sensor data with the team.

Full PDF reports generated in the app save significant time in the post-processing of data.

Wireless Technology

 Easily monitor sensor data wirelessly using the SmartRock app on a smartphone or tablet.

Team Data Sharing

Sensor data is automatically shared and updated across your teams devices, ensuring everyone has the most updated results.

Optimise Breaktests

Concrete cylinder break tests can be minimized or eliminated using the maturity function of the SmartRock™

ASTM Strength Estimation

Using the ASTM C1074 standard for maturity-based strength, SmartRock™ can accurately estimate the strength of concrete over time.

Reading Range
  •  -30 to +80 °C
  • -22 to +176 °F


  • ±1 °C (1.8 °F)
  • 0.5 °C (0.9 °F)
Wireless Range
  • Up to 8 meters*
  • Up to 26 feet*
  • *The recommended depth for embedding the transmitter part of the sensor in concrete is 5 cm (2 inches). Within this depth, the user can communicate easily with the sensor at a distance of about 8 meters. The temperature sensor extension cable [40 cm (16″) long] can then be placed anywhere within the concrete element.
Measurement Interval
  • Every 30 minutes (1500 Data Points i.e. 31 days)
  • Lasts up to 4 months
  • 38 x 38 x 12 mm
  • 1.5 x 1.5 x 0.5 inches
  • 30 grams (regular cable length)
Cable Length
  • Regular: 40 cm (16 inches) 
  • Long: 3 meters (10 feet)
Installation Depth
  •  Recommended within 5cm (2 inches)
