Accurate Monitoring of Concrete with a Cast-In-Place Device

Measuring the relative humidity of concrete is a complex process. ASTM F2170 is currently the standard for embedded monitoring relative humidity in newly placed concrete. The process requires a hole to be drilled and cleaned before inserting a relative humidity probe to begin monitoring relative humidity. The measurements are obtained within a specific volumetric space in the concrete.We believe the post-drilling process involves many dependencies, special considerations, and extreme care. With little tolerance for error, this process may lead to misleading results putting the installer at higher risk of installation failure, expensive repairs, and making project decisions based on potentially flawed data. We have invented a cast-in-place device that meets the volumetric space requirements of ASTM F2170 and does not encounter similar issues as noted with the current post-installed sensor. A cast-in-place device eliminates the issues related to drilling and cleaning the concrete hole with the post-installed sensor.
