DESCRIPTION: This presentation provides an in-depth look at below-slab moisture and vapor protection.

We will examine how below-slab water vapor migration has become the leading cause of floor failures, as well as potential contributor to mold growth, alkali-silica reaction, efflorescence, and other building envelope concerns. Moreover, the seminar is designed to equip attendees with a knowledge of the current requirements of the standards and recommendations from ASTM, building codes, ACI, and PCA, as well as flooring and concrete experts from the industry. We will address a variety of important technical topics, such as: when and where to use vapor protection, the use of poly/visqueen, the location of the vapor barrier, sand layers, soil gases, concrete moisture testing, concrete drying, and what practices are required by ASTM E1643 to achieve effective installation (field photo examples will be included and discussed).

There is no cost to participate in this seminar.
