Waterproofing as Part of the Continuous Air Barrier

Track 1: Air Barriers

Wednesday, May 11, 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.

Trinidad Martinez, RRO, CEI, Sprat I

Terracon, Austin, TX

Trinidad is currently a Senior Staff Architect in Terracon’s Austin, Texas Facilities office. He evaluates the integration of building envelope systems and addresses conditions that may adversely impact the durability and resistance of the building envelope systems to air and water penetration and other specified performance requirements that encompass the building envelope. Trinidad manages various commercial and multi-family projects that pertain to the building envelope during the design and construction phases and evaluates the building envelope with quality assurance field observation and various methods of field testing such as AAMA 502 (ASTM E1105 and ASTM E783), AAMA 501.2, High voltage-ELD, and ASTM D7954. He is also a Level 1 Society of Professional Rope Access Technician (SPRAT) and performs field observations of buildings with difficult access.

Prior to becoming a Building Envelope Consultant in 2016, Trinidad was in the U.S. Army for 8 years as an all-source analyst and attended the University of Texas at San Antonio (UTSA) and received an undergrad degree in Architecture. During that time Trinidad also worked in the construction fields performing various task during the construction process. His experiences working in the construction industry at various levels and disciplines bring a unique perspective to any team he is a part of.
