Moisture Vapor Emission Testing

The migration of water vapor through concrete slabs and walls is often the primary cause of adhesion related failures of floor coatings, floor toppings, and primary containment linings. Osmotic blistering and delamination are often the result of high moisture vapor emissions.

Nationally, costs associated with these types of coatings failures, considering materials, labor, and revenue loss associated with downtime and disruption to facility operations amount to millions of dollars annually.

To determine whether too much moisture is present within the concrete or is migrating through the concrete, Surface Solutions will perform a Calcium Chloride Test in accordance with ATSM F1869, “Standard Test for Measuring Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride.”

Testing the moisture vapor transmission rate of the concrete slab is just one of many necessary precautions Surface Solutions takes in order to deliver the right solution to the customer the first time.
