Moisture coming from, or through a concrete floor slab, can lead to conditions that are damaging to floor coverings, coatings, the building’s environment, and the ability to store moisture sensitive products directly on a floor slab.  In this webinar, attendees will learn where potentially damaging levels of moisture come from, how moisture migrates, and what design measures are an absolute necessity to minimize the risk of moisture-related problems.

Learning Objectives:

  2. Understand how moisture migrates.

  4. Learn how long does it take a concrete floor slab to dry.
