Today’s construction industry demands accurate, real-time concrete strength measurement and concrete temperature monitoring to ensure structural integrity and safety while optimizing construction schedules and cost efficiencies.
Unlike all other testing methods, our concrete strength sensors provide the only non destructive concrete testing solution in the world that can directly measure in-place concrete strength in real time, the development of a maturity curve, or any reliance on specific concrete mix design assumptions. If a concrete mix needs to be changed mid-project, no problem – our smart concrete sensors remain unaffected by changes to concrete mix design, offering consistent concrete quality control and flexibility.

Current concrete strength testing methods can be expensive and time-consuming, relying on small samples from much larger concrete structures or assumptions about concrete mixtures and reference calibrations.
Direct costs associated with destructive concrete testing can range from $4 to $12 per cubic yard of concrete per testing party, depending on the number of samples taken and whether third-party labs are used. This figure does not account for the indirect costs related to inaccuracies, inefficiencies, and waste linked to traditional testing methods, highlighting the need for innovative solutions like non-destructive concrete testing and real-time concrete strength measurement.
Destructive Concrete Strength Testing
The industry standard for testing concrete strength involves breaking multiple field-cured concrete samples (cylinders or beams). This practice has remained largely unchanged since the early 19th century.
There are numerous disadvantages associated with destructive concrete testing, including inaccuracies, quality control issues, inter-user variability, time inefficiencies, labor intensiveness, material waste, and expense. Despite these drawbacks, destructive strength testing is often seen as “the way it’s always been done”, underscoring the need for more effective alternatives like non-destructive concrete testing and innovative concrete strength sensors.
Maturity Testing
Although concrete maturity testing, like the Wavelogix’s REBEL System, allows for real-time concrete strength monitoring, it still requires making and breaking concrete samples and the lab development of a maturity curve for each concrete mix used on a job. This testing and calibration can cost several thousand dollars and can take weeks. Such an approach is not feasible when concrete mixes need to be changed mid-stream during a project, which is a common occurrence. Additionally, maturity testing relies solely on temperature to estimate concrete strength without considering hydration or other environmental factors. This limitation renders maturity testing irrelevant for acceptance testing at 28 days or any time point beyond 3 days, when temperature fluctuations are occurring.
OUR BREAK-FREE APPROACH
Our REBEL Concrete Strength and Temperature Sensing System is unique compared to all other concrete strength testing and monitoring methods and technologies in that it uses piezoelectric sensors coupled with electromechanical impedance (EMI) analysis to deliver a cutting edge solution to a century-old problem.
How It Works
Wavelogix’s REBEL concrete strength sensors are incredibly easy to install and operate. Much like concrete maturity sensors, each sensor is placed within the concrete formwork and embedded in freshly poured concrete. REBEL then collects, in real-time, concrete strength data that is wirelessly transmitted back to the end-user, similar to concrete maturity sensor applications.
1
INSTALL SENSOR TO GET STARTED
Simply lay the REBEL sensor on the ground of the concrete formwork or secure the sensor to rebar reinforcements with zip ties, then cover it with concrete.
2
CONNECT SENSOR CABLE TO DATALOGGER
Plug the REBEL sensor cable into the reusable, auto-start datalogger for seamless data transmission.
3
MONITOR REAL-TIME CONCRETE STRENGTH RESULTS
Directly measure and monitor real-time changes in concrete strength 24/7 at your fingertips – using your cell phone, tablet, or other device of choice – for as long as strength data is required (up to 28 days and beyond).
The Rebel Difference
Our concrete strength sensors convert the mechanical properties of concrete into electrical signals, providing highly accurate and real-time information regarding in-place concrete strength. This data is essential for determining optimal timing for traffic opening, pulling post-tensioning tendons, and striking vertical formwork. Unlike traditional methods, our system eliminates the need for creating maturity curves or other calibrations, and it remains unaffected by concrete mixtures, weather conditions, or any changes in those mixtures or conditions throughout the course of a project.
