Waterproofing as Part of the Continuous Air Barrier

Track 1: Air Barriers

Wednesday, April 8, 9:45am – 10:45am

ABAA has traditionally addressed air barriers associated with a building’s façade and has not evaluated waterproofing systems used for below grade or horizontal deck waterproofing applications. This presentation will look for those areas of a building’s continuous air barrier that are not covered with traditional ABAA air barrier systems, roof systems or window systems. Recognition that ABAA only addresses a portion of the building’s air barrier begs the question of who/how is the balance of the building’s air barrier being addressed. Below grade and elevated deck waterproofing systems may cover some of these other areas and can be critical to the building’s air tightness. This presentation will review various waterproofing systems and issues associated with their installation.

Learning Objectives:

  1. Understand how waterproofing may be part of a building’s air barrier.
  2. Review available waterproofing systems, their service life and warranty.
  3. Review critical installation parameters and challenging details.
  4. Review field testing methods available for waterproofing systems.
