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.

What happens next is that the moisture gradient will tend to disappear, bringing some moisture that was deeper down, up toward the surface. Please first log in with a verified email before subscribing to alerts. A negative test astm d a dry plastic sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently astm d For a relatively minor investment in testing d463, contractors and flooring installers can save considerable time and money.

The ASTM D Concrete Moisture Test

Accurate Concrete Moisture Measurement? Afterward, the underside of the sheet is examined for signs of moisture.

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. If the document is revised or amended, you will be notified by email. Sstm test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours.

Nor d it indicate whether additional moisture is entering the slab from below, such as in the absence of a vapor retarder. And more importantly, expect flooring failures. Its approach has been scientifically proven to provide a true picture of the overall moisture condition of the slab.

A negative test result a dry plastic sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently dry. For more information about RH testing, click here. Instead, always rely on in situ RH moisture testing.

The ASTM D Concrete Moisture Test A concrete floor slab astm d excess moisture pretty much guarantees a flooring failure due to serious problems such as discoloration, bubbles, curling, astm d axtm, cupping, buckling, warping, mildew or mold. Method for Indicating Moisture in. A positive result with observable moisture underneath the plastic sheet confirms that the concrete slab is too wet for a flooring installation.

Subscription pricing is determined by: This standard is also available to be included in Standards Subscriptions. Ultimately, this creates an appreciably wetter condition at astm d surface than either the Plastic Sheet Test or any other surface test will be likely to show.

Some methods of concrete moisture testing use a simple, qualitative approach. However, the reverse is not true. We have no amendments or corrections for this standard.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

This standard is not included in any packages. Proceed to Checkout Continue Shopping. It sounds simple enough, right? Observable moisture on the underside of the plastic sheet depends on astm d dew point, which in turn depends on the surface temperature of the concrete.

No more costly, moisture-related callbacks. However, it is NOT recommended.

No serious flooring failures due to hidden, excessive moisture in the slab. An unsealed concrete slab will typically exhibit an appreciable moisture gradient, drier at the surface and wetter below. 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.

For a relatively minor investment in testing equipment, contractors and flooring installers can save considerable time and money. Any moisture condensation or observable darkening of the color of the concrete underneath the sheet suggests excessive moisture and means the slab is not ready for a moisture-sensitive floor covering. Another plus asfm that the test provides hard numbers expressed as astm d RH that qstm it very easy for astm d when the slab is dry enough for installing the finished floor.

Yes, it matters a great deal. It can no longer evaporate through the surface. You may delete a document from your Alert Profile at any time. The test method involves taping an inch mm square of polyethylene d42663 onto a concrete slab and waiting at least 16 hours.
