Vapor Barriers Under Concrete Slabs - How to Select and Locate

COURSE NO: T01-001
COURSE PROVIDER: Brian McCaffrey, P.E.
Vapor Barriers Under Concrete Slabs - How to Select and Locate
Course Highlights

This online engineering PDH course provides guidelines on how to properly select and locate a vapor barrier and how a vapor barrier can help earn LEED credits for building design.


A vapor barrier is one of the most critical building components used to prevent indoor air quality issues and minimize moisture-related concrete slab and flooring system failures. Proper selection of a vapor barrier based upon the criteria of low permeance, high tensile strength, high puncture resistance, and chemical resistance will ensure that the vapor barrier not only performs as an effective barrier to moisture and other vapors, but will also maintain its physical integrity during the placement of the concrete slab.


This 1 PDH  online course is intended for engineers and architects who are involved with the design of waterproofing/vapor barriers for building construction.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • How to properly select a vapor barrier
  • How to properly locate a vapor barrier, either directly below a concrete slab or under a granular base and concrete slab
  • How to prepare a specification for a vapor barrier
  • How to earn LEED credits for including a vapor barrier in the building design
