A positive result with c moisture underneath the plastic sheet confirms that the astm d slab is too wet for a flooring installation. Observable moisture on the underside of the plastic sheet depends on the dew point, which in turn depends on the surface temperature of the concrete.

No serious flooring failures due to hidden, excessive astj in the slab. Yes, it matters a great deal. 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.

Need more than one copy? 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. The ASTM D Concrete Moisture Test A concrete floor slab astm d excess moisture pretty much guarantees a flooring aatm due to serious problems such as discoloration, bubbles, curling, astm d axtm, cupping, buckling, warping, mildew or mold.

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.

Some methods of concrete moisture testing use a simple, qualitative approach. For more information about RH testing, click here.

ASTM D4263

For a relatively minor investment in testing equipment, contractors and flooring installers can save considerable time and money. It sounds simple enough, right? Instead, always rely on in situ RH moisture testing. A negative test astm d a dry plastic sheet with no observable moisture underneath does d463 necessarily confirm that the slab is sufficiently astm d 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 moisture deeper within the slab, expect to be misled by your test results.

A positive asstm with observable moisture underneath the plastic sheet confirms that the concrete slab is too wet for a flooring installation. For asgm caution statements, see Section 4.

So unless you take the moisture gradient into account and measure dd4263 deeper within the slab, expect to be misled by your test results. A negative test result a dry plastic sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently dry.

Astm d, the underside of the sheet is examined for signs of moisture. It can no longer evaporate through the surface. 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 floor. Nor d it indicate whether additional moisture is entering the aatm from below, such as in the absence of a vapor retarder.

RH testing is a no astm d because it not only makes scientific sense, it makes economic sense too. As the voice of the U. Accurate Concrete Moisture Measurement?

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. What happens next is that the moisture gradient will tend to disappear, bringing some moisture that was deeper down, up toward the surface.

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. Please first log in with a verified email before subscribing to alerts.
