To avoid guessing how much moisture is actually in the concrete slab, you should use RH testing, which reads deeper in the concrete than the CaCl method. Scientific research determined that testing at 40% of the slab’s .When Not to Use a Concrete Moisture Meter; Wood Flooring Over Concrete: Moisture Management Is Still Vital; Project Owners. . Given the realities of moisture in concrete and the necessity of measuring the moisture condition .The Tramex Concrete Moisture Encounter is a non-destructive meter for measuring moisture content instantly in concrete slabs per ASTM F2659, featuring Carbide Method equivalent scales for concrete and anhydrite screeds. Easy-to-use, giving precise and repeatable results, the Concrete Moisture Encounter allows the user to make multiple tests over a large area in the .
Installers can quickly assess the surface MC of subfloor integrity with a concrete moisture meter or building inspection meter to find potential trouble spots in existing slabs, although newly-poured slabs would do better with a thorough moisture assessment by RH testing. Accurate moisture testing is crucial for the flooring product and any .
Concrete moisture testing methods, like calcium chloride (MVER) or the concrete moisture meter, test the surface of the slab. But they fail to take into account an important aspect of concrete drying: the moisture gradient, or moisture differential, as it’s called in the American Concrete Institute’s Guide for Concrete Slabs that Receive Moisture . See It This multifunctional moisture meter helps DIYers test for moisture using pinless, flat sensors without damaging the material. If the meter finds moisture, the user can remove the cap to .

The PosiTest CMM Concrete Moisture Meter is the fast, non-destructive impedance meter ideal for inspectors looking to quickly evaluate the moisture condition in concrete slabs. Easily collect and report measurements in conformance with ASTM F2659.
Although concrete moisture meters may be useful as relative measurement devices, they should not be treated as a quantitative test. In observance of Labor Day, we will be closed Monday, September 2nd. . The installer used an electrical impedance meter to measure the moisture in the slab. Reading ranged from 3’s to 6’s.
Most “Concrete” Moisture Meters Only Check Surface Moisture. Concrete slabs often have thicknesses measured in feet, not inches. Moisture meters can only check the moisture near the surface of a concrete slab, which is not sufficient for predicting how the slab will react to having sealant applied or other building materials installed over it. As we mentioned earlier, one of the challenges with concrete slabs is hidden moisture. Though a concrete moisture meter can help indicate moisture “hotspots,” it doesn’t measure much beyond one-inch deep. The ASTM F2170 standard recommends using the relative humidity test, which involves drilling down to 40% depth of the concrete when .
The primary source of moisture in a concrete slab is the proportion of water mixed with the cement. No water source has a greater impact on the time it will take concrete to dry. Yet you have other water sources to worry about. Potential external water sources at a worksite can affect slab drying and curing. 1. Weather and ElementsOnly a top quality quantitative concrete moisture meter like the Tramex Concrete Moisture Encounter, the CME5 and CMEX5, provides quantitative readings of the actual moisture content in the concrete floor or slab. The best and most accurate concrete moisture meters have been calibrated using gravimetric testing as a baseline.
RH in situ testing, like the Rapid RH® L6 Smart Sensors, can accurately determine the concrete slab’s moisture condition. Can Water Go Through Concrete? Water can move through concrete via capillary action and external sources such as ground moisture. Furthermore, concrete can absorb moisture from the air depending on the relative humidity.So, we’ve put together a list of tips for measuring concrete moisture using both moisture meters and the (more reliable) ASTM F-2170 standard. .

Non-destructive test (NDT) mode: The Tramex Concrete Moisture Encounter CMEX5 is a non-destructive digital multi moisture meter for concrete floors and slabs providing instant and precise quantitative measurement of moisture content using Gravimetric testing as a baseline.The CMEX5 also provides Carbide Method equivalent readings for concrete and .Wagner Meters is proud to offer the updated online course, “Moisture Testing of Concrete Floor Slabs.” This free training webinar – presented by Howard Kanare, a leading expert in concrete moisture issues – is especially relevant for building inspectors, contractors, and flooring installers who may need to understand, detect, and . Those pathways go two directions so that unsealed concrete can also absorb moisture, whether through contact with a direct water source (like groundwater or leaking plumbing) or through ambient moisture. Once the concrete has been sealed, moisture continues to move within the slab until it reaches a state of balance referred to as equilibration.
Pin-type moisture meters are the most common type and are suitable for measuring moisture levels in concrete slabs. Non-invasive moisture meters are ideal for measuring moisture levels in thicker concrete structures, such as walls or floors. Other types include capacitance moisture meters, which work by measuring the electrical charge across . Jason, Great information, Thank you. I am testing to see if a concrete slab in a ground floor condo unit is good or bad. By the test requirements outlined above and complete by an engineering firm then read at 72 hours the RH=99% and MVER 5.78 and 5.95 emitted from 1000 SF of floor are in 24 hours. Since most of concrete’s moisture is located at the bottom of the slab, the deeper measurements will provide a more accurate understanding of the concrete’s moisture levels. All you have to do is drill several holes in the concrete, place probes inside, and wait 24 hours for the probes to equilibrate.
According to ASTM F2170, when drying, concrete slabs have lower moisture levels near the surface and higher levels towards the bottom of the slab. Therefore, measuring RH levels at 40% depth of the slab (20% depth if drying on two sides), is more representative of the overall humidity conditions of the concrete.
Concrete Moisture Meters. Concrete moisture meters use electrical impedance and resistivity to test for moisture in a slab. However, concrete moisture meters, like the calcium chloride test, can only evaluate surface moisture levels. In addition, concrete moisture meters are largely affected by different concrete mixes. Some major factors are:

Multi-use non-destructive concrete moisture meter for quantitative %mc, front-lit display, built-in ambient rh sensor, in-situ rh & pin probe connections, 500+ wood species available . Tramex .A concrete moisture meter, like the C555 concrete moisture meter from Wagner Meters (coming soon), can provide immediate qualitative slab assessment. This concrete moisture meter does not replace RH testing—rather, this moisture meter can quickly scan the surface of the slabs and indicate areas which may need to be assessed with a more .
A concrete moisture meter that complies fully with ASTM F2659, like Wagner’s C555, can be used to determine higher or lower concentrations of moisture within a concrete slab. Concrete moisture meters should never be used to determine the moisture condition of a concrete slab at the time when flooring materials will be applied.
