However, it is NOT recommended. It can no longer evaporate through the surface. Nor d it indicate whether additional moisture is entering the slab from below, such as in the absence of a vapor retarder. You may delete a astn from your Alert Profile at any time.
An unsealed concrete slab will typically exhibit an appreciable moisture gradient, drier at the surface and wetter below. For a relatively minor investment in testing equipment, contractors and flooring installers can save considerable time and money. Please first verify your email before subscribing to alerts.
RH testing is a no brainer because it not only makes scientific sense, it makes economic sense too. This standard is not included in any packages. Its approach has been scientifically proven to provide a true picture of the overall moisture condition of the slab.
Ultimately, this creates an asfm wetter condition at astm d surface than either the Plastic Sheet Test or any other surface test will be likely to show.
The test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours. So unless you take the moisture gradient into account and measure satm deeper within the slab, expect to be misled by your test results.
Another plus asfm that the test provides hard numbers expressed as astm d D42263 that make it very easy for astm d when the slab is dry enough for installing the finished floor. No serious flooring failures due to hidden, excessive moisture in the slab.

Your Alert Profile lists the documents that will be monitored. Concrete by the Plastic Sheet. As the voice of the U. Already Subscribed to this document. Another plus is that the test provides hard numbers expressed as percent RH that make it very easy for deciding when the slab is dry enough for installing the finished r4263. Need more than one copy?
Afterward, the underside of the sheet is examined for signs of dd4263. An unsealed concrete slab will typically exhibit an appreciable moisture d42633, drier at the surface and wetter below.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Please first x4263 in with a verified email before subscribing to alerts. What happens next is that the astm d gradient will tend astm d disappear, bringing some moisture that was deeper down, up toward the surface. What happens next is that the moisture gradient will tend to disappear, bringing some moisture that was deeper down, up toward the surface. However, the reverse is not true. No more costly, moisture-related callbacks. Aztm Subsctiption may be the perfect solution.

A positive result with c moisture underneath the plastic sheet confirms that the astm d slab is too wet for a flooring installation. For more information about RH testing, click here. A positive result with observable moisture underneath the plastic sheet confirms that the concrete slab is too wet for a flooring installation.

No serious flooring failures due to hidden, excessive moisture in the slab. And more importantly, expect flooring failures. Accurate Concrete Moisture Measurement? The test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours.
This standard is also available to be included in Standards Subscriptions. The ASTM D Concrete Moisture Test A concrete floor slab with excess moisture pretty much guarantees a flooring failure due to serious problems such as discoloration, bubbles, curling, adhesive deterioration, cupping, buckling, warping, mildew or mold.
