Vapor Barriers: Nuisance or Necessity?

This Lunch + Learn provides an in-depth look at below-slab moisture and vapor protection. The seminar will examine how below-slab water vapor migration has become the leading cause of floor failures, as well as a potential contributor to mold growth, alkali-silica reaction, efflorescence, and other building envelope concerns. Moreover, the seminar is designed to update attendees on current standards and recommendations from ASTM, ACI, and PCA, as well as flooring and concrete experts from the industry. Questions about vapor retarders vs. vapor barriers, the use of poly/visqueen, the location of the vapor barrier, radon gas, concrete moisture testing, concrete drying, and effective installation will be addressed.


Free! Lunch will be provided thanks to Stego Industries. Find out more about vapor barriers.
