Moisture Concerns in Concrete Construction

Moisture vapor emissions through a concrete slab in any building can contribute to costly floor good failures and down time.

Over the past 20 years, the frequency of moisture vapor emission issues has increased. Several contributing factors include:

  • The loss of asbestos as an ingredient in resilient flooring
  • The loss of solvents from adhesive and coating systems
  • Increased use of water for easier placement of concrete
  • Fast track construction schedules

High pH (alkalinity) can be extremely detrimental to latex-based adhesives as well. Moisture vapor moving through the concrete to the surface will accumulate at the bond line between adhered flooring material and the concrete. The combination of moisture and salts present in the concrete combine to create a high pH environment. The high pH condensate begins to break down the water-based adhesive, resulting in a floor good failure.

There are numerous moisture vapor barrier options on the market to reduce moisture vapor emissions migrating through concrete. Maxxon Corporation, known throughout the industry for high quality floor underlayments and sound control mats, also offers two moisture vapor barriers to aid in moisture mitigation. See the Product Update below for information on Maxxon MVP.
