Vapor barriers beneath concrete slabs on grade are critical for controlling moisture vapor infiltration from the ground. This course provides an overview of vapor barriers used beneath concrete slabs on grade and in crawl spaces, showcasing common flooring failures that occur when a slab is not properly protected. We’ll explore how moisture enters and moves in the concrete, review key prevention and testing methods, and examine relevant industry standards and specification guidance. Finally, we’ll apply these concepts to practical case studies.
