SmartRock® 2

Product discontinued: SmartRock 2 is now a Giatec legacy product. Learn more about the SmartRock 3 here.


Rugged & Reliable

Installs directly onto the rebar with no cumbersome wires or expensive data loggers. Temperature and strength readings are immediately sent to an intuitive mobile app.


The Highest Standards

Eliminate reliance on error-prone cylinder break tests. SmartRock estimates concrete maturity accurately based on the ASTM C1074.


Finish Projects Faster

Make critical, real-time decisions during concrete curing. Help crews hit project milestones faster, saving days or weeks off construction schedules.

SmartBox™  | Wireless Concrete Resistivity

Monitor Curing of Concrete in

SmartRock is the most widely used wireless concrete sensor in the world, helping construction companies build structures faster, safely, and more efficiently. These user-friendly sensors are easily installed in the concrete formwork (on the rebar) before pouring to monitor in-situ temperature and maturity according to ASTM C1074. The wire-free logger continuously records the measured temperature of any concrete pour in real-time. These results are then downloaded and analyzed automatically onsite (to determine the in-place concrete strength) using the free SmartRock app (available for both Android/iOS mobile devices).

Battery Life Up to 4 months after installation

How long is the battery life? 

The battery life is about 4 months under room temperature. 

Do MTO and DOTs allow this method of concrete strength measurement? 

The strength estimation according to the concrete maturity method as described in the ASTM C1074 has been specified by many DOTs in the US as well as the CSA. Here is the clause from CSA: 

“ In-place strength Test procedures 
Unless otherwise specified by the owner, the in-place strength shall be determined in accordance with CSA A23.2-14C, CSA A23.2-15C or ASTM C1074 for the purposes of determining: 
(a) when forms shall be removed or when prestressing or post-tensioning shall be applied; (b) when curing shall be terminated; and (c) when re-shores shall be removed.” 

What is the maximum depth I can place the SmartRock? 

We recommend a maximum depth of 2 in (5 cm) to ensure that the signals from the sensor are strong enough. The signal strength weakens as you place the sensor deeper. 

Can I get SmartRock with longer thermocouple cables? 

Yes. Please ask for customized length when you are ordering your SmartRock package. You can get this cable as long as 10 ft.
