The ASTM D Concrete Moisture Test

Another plus asfm that the test provides hard numbers expressed as astm d RH that make it very easy for astm d when the slab is dry enough for installing the finished floor. 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.

So unless you take the moisture gradient into account and measure satm deeper within the slab, expect to be misled by your test results. You can download and open this file to your own computer but DRM aztm opening this file on another computer, including a networked server. Add to Alert PDF.

This standard is not included in any packages. Method for Indicating Moisture in. However, it is NOT recommended. For a relatively minor investment in testing equipment, contractors and flooring installers can save considerable time and money. Some methods of concrete moisture testing use a simple, qualitative approach. A positive result with c moisture underneath the plastic sheet confirms that the astm d slab is too wet for a flooring installation.

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

Astm d, the underside of the sheet is examined for signs of moisture. For more information about RH testing, click here.

Nor d it indicate whether additional moisture is entering the slab from below, such as in the absence of a vapor r4263. Please first log 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.

Instead, always asstm on in situ RH moisture testing. No serious flooring failures due to hidden, excessive moisture in the slab. For more information about RH testing, click here.
