Nor d it indicate whether additional moisture is entering the slab from below, such as in the absence of a vapor retarder. Yes, it matters a great deal. No more costly, moisture-related callbacks. An unsealed concrete slab will typically exhibit an appreciable moisture gradient, drier at the surface and wetter below. Any moisture condensation or observable astj 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.

However, it is NOT recommended. We have no amendments or corrections for this standard. Ultimately, this creates an appreciably wetter condition at the surface than either the Plastic Sheet Test or any other surface test will be likely to show. 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. However, it is NOT recommended.

And more importantly, expect flooring failures. It sounds simple enough, right? So unless you take the moisture gradient into account and measure satm deeper within the slab, expect to be misled by your test results.

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 Some methods of concrete moisture testing use a simple, qualitative approach.

RH testing is a no brainer because it not only makes scientific sense, it makes economic sense too. Need more than one copy? For a relatively minor investment in testing equipment, contractors and flooring installers can save considerable time and money. The test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours.

An unsealed concrete slab will typically exhibit an appreciable moisture gradient, drier at the surface and wetter below. It can no longer evaporate through the surface. Adtm Subscribed to this document. Yes, it matters wstm great deal. A negative test result a dry plastic sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently dry.

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.
