Concrete Moisture Meters vs. Relative Humidity Testing

Calcium Chloride Moisture Test vs. Relative Humidity

By Jason Spangler in Calcium Chloride/MVER Test Concrete Information & Knowledge Base | 12 Comments

All types of flooring can be susceptible to failure if moisture conditions are not properly monitored and maintained. But a slab’s moisture condition begins long before the flooring is installed. If the concrete slab has not been properly dried and cured before the flooring is installed, moisture problems are almost guaranteed. Moisture-related problems in flooring […]

Concrete pH Balance for the Same Price as Relative Humidity

By Jason Spangler in Relative Humidity (RH) Testing Concrete Information & Knowledge Base | 0 Comment

All liquids in which water dissolves additives have a pH level, a measure of acid vs. alkaline (basicity) content. That’s pH. The pH scale ranges from 0 to 14, although reading can exceed either end of that range. Battery acid has a pH of zero.

Mapping Out Your RH Test

By Jason Spangler in Relative Humidity (RH) Testing Concrete Information & Knowledge Base | 2 Comments

In situ probes are a key element of relative humidity (RH) testing and of a contractor’s ability to accurately measure concrete slab moisture conditions because of their placement within the concrete slab. Once installed, builders must allow Wagner Meters’ Smart Sensors to equilibrate. But what is the strategy for proper sensor placement and for RH […]

Calibration for RH Testing Made Easy

By Jason Spangler in Relative Humidity (RH) Testing Concrete Information & Knowledge Base | 0 Comment

Relative humidity (RH) moisture testing in concrete requires a properly calibrated in situ probe to ensure accuracy. Calibration certainly makes good sense for your own protection in case any moisture-related issues arise in the future. In addition, compliance with ASTM F2170 certainly requires calibration and its accompanying documentation. So any way you look at it […]

External Influences on Internal Concrete Moisture Condition

By Jason Spangler in Concrete Chemistry Concrete Information & Knowledge Base | 4 Comments

There are several external factors that influence the moisture condition of a concrete slab. They are: Time Vapor retarders Bond breaking agents Heating, ventilation, and air-conditioning (HVAC) Concrete slab construction is an exercise in convergence. Builders apply several methods of facilitating the successful curing, drying, and hydration of concrete slabs. However, those processes and building […]
