When planning to install any type of flooring or finishing product over a concrete floor only rh testing like the rapid rh l6 can provide accurate affordable and industry compliant concrete moisture testing.
Testing concrete floor moisture. How to test a concrete floor for excessive moisture. Concrete must always contain some moisture but it cannot be an excessive amount. It s important to understand the testing process on concrete subfloors and the implications of moisture on flooring performance in order to plan project timelines and budgets accordingly and to. Moisture testing moisture testing is an essential part of determining the suitability of a concrete slab to receive a resilient floor covering.
Floormedics has developed a national concrete moisture testing program specifically for commercial projects. A second direct test astm f 1869 standard test method for measuring moisture vapor emission rate of concrete subfloor using anhydrous calcium chloride was standardized in the 1990s by the subcommittee on practices of the committee on resilient floor coverings. Concrete slabs are naturally breathing elements of a home readily taking in moisture and air expanding and contracting and shifting with nature. Concrete moisture test how to test for moisture in a concrete floor or slab.

Our responsibility is to offer an honest unbiased data backed evaluation of any moisture issues that exist within a concrete slab. When it is the moisture levels can cause floor coverings to fail. A definitive test that measures the amount of moisture released from the concrete requires a calcium chloride kit or a relative humidity meter.
The second test is the astm f 1869 standard test method for measuring moisture vapor emission rate of concrete subfloor using anhydrous calcium chloride and it was standardized in the 1990s by the subcommittee on practices of the committee on resilient floor coverings. Concrete slabs and floors can be excellent subfloor surfaces for tile and other floor coverings but too much moisture in the concrete can cause problems with flooring installations. Doing a concrete moisture test before you install any type of flooring over a concrete floor or slab is important because too much moisture vapor transmission mvt can delaminate flooring materials like epoxy linoleum laminate tile can buckle wood floors and can cause mildew in carpeting.
