Acceptable moisture levels in concrete according to astm standard when testing via astm f2170 the rh level of a concrete slab needs to be at or below 75 unless the flooring system manufacturer provides alternate guidelines. When you read in a sealer data sheet that the mver needs to be 3 pounds or 5 pounds what that means is the number of pounds of water vapor per 1000 square feet per 24 hours.

So how can you be sure if the walls in a structure have a safe level of moisture. In extreme cases moisture intrusion leads to spalling and could even necessitate wall replacement. Liquid water from rain or ground water. Moisture supports the growth of mold and causes wall coatings to blister and peel.

For example if the temperature in the room is around 80 degrees fahrenheit and the rh is 50 then a safe level of moisture in the wall would be about 9 1 mc. Water vapor leaves the surface of a concrete slab at a rate that is called the moisture vapor emission rate mver. Concrete is like a sponge absorbing moisture from under the concrete which causes the moisture to come up through the concrete capillaries. Rising damp usually occurs in masonry.
