good is indicated for moisture levels below 80%, yellow or questionable for 80% to 86%, and red or not recommended for moisture levels above 86%. ASTM Standard D4263 describes a test for indicating moisture in concrete. A sheet of plastic approximately 18 inches square is tightly taped to the concrete surface so that the edges are totally sealed.Problem Solving Forum : Durability + Design,Concrete surfaces at or below grade subject to osmotic pressure create a much different issue. Coatings subjected to osmotic pressure must be able to bond into the concrete matrix well enough to resist the pressure, and acrylic systems generally will not perform to this level. At best, testing methods to determine moisture in concrete are iffy.FITTING Moisture Readings - Chaunceys,level of dryness of the screed/concrete.

Problems Underfoot - Concrete Moisture Test

To help ensure that high moisture levels do not end up causing a problem after installation, it is paramount that installers get an accurate measurement of the moisture levels in the slab. Concrete moisture, of course, starts with the original aggregate mix. This moisture dissipates through surface evaporation as the slab cures.3 Ways Humidity Can Damage Concrete,Increased pH levels: Relative humidity levels directly affect the pH levels in concrete. For this reason, concrete manufacturers create regional guidelines for installers to follow, as some areas in the country are drier and have different field pH levels. When relative humidity levels are high, the moisture increases the concrete’s pH levels.The Environment of Successful Building,-,In fact, the moisture content levels in concrete form the core of successful building.,The Environment of Successful Building Part I: The Envelope.

Moisture Meter Test. Electrical impedance meters are one way to measure moisture and quickly survey the condition of a concrete slab. They’re also useful in searching for moisture problems that may occur at the perimeter of the room or around pipes that may be leaking below ground. Simple place the meter flat on the concrete and read theWhy Flooring Professionals Must Test For,Concrete and Moisture. Concrete is porous material. The more porous it is, the greater the potential for moisture vapor to move at a volume harmful to the floor covering. Concrete slabs with a high moisture emission rate and/or too high a pH level will always be detrimental to a successful flooring installation.Concrete Surface Moisture Levels | Godfrey,The current Australian Standard states 70% Rh as the highest surface moisture level recommended, however Godfrey Hirst will fully guarantee the performance of our carpet tiles when tested as up to an RH level of 80% and a pH level of 12 without the use of a moisture barrier provided Green Solutions GS - 444 pressure sensitive adhesive
