Moisture Emission Test Kits are the most recognized method to determine moisture emission through concrete floor slabs. Millions of dollars in damage to coatings and flooring systems occur every year as a result of moisture migration through concrete slabs and structures. Electronic moisture meters indicate the existing degree of saturation but not the rate of moisture emission.

A container of moisture-absorbing calcium chloride is weighed and placed under a plastic "dome" that is sealed to the concrete surface with a self-adhering gasket. At the conclusion of the 60 to 72-hour test cycle, the plastic is cut open and the dish of calcium chloride is removed and immediately weighed. The weight gain and exposure time values are used to compute the test result, expressed in pounds of moisture emitted per 1,000ft² in 24 hours. Recommended test frequency is three for the first 500ft² and one test for each additional 500ft² of total area.

Each test kit consists of a sealed calcium chloride dish and a plastic dome with a pre-installed butyl rubber gasket. Three pH test strips with a color chart are also included. Test kits are supplied in a pack of three or twelve. For a complete evaluation of concrete floor surface, see Moisture Meters and pH Meters. The OB-205 Balance is recommended for quick evaluations in the field.
