Plaza decks are highly complex assemblies that must safely support people, vehicles or landscaping over occupied spaces while protecting the building from water intrusion. Improper design or detailing can lead to leaks, structural deterioration, and safety risks for occupants. This course examines protected membrane (IRMA) waterproofing systems used in plaza deck applications and explains how they differ from traditional roofing assemblies. Participants will learn how proper slope, drainage, detailing and system selection help manage water, reduce risk and extend service life. The course also reviews common failure points and waterproofing options to help design professionals create plaza decks that are durable, watertight and supportive of occupant health, safety and welfare.

Upon completion of this course, the Learner should be able to:

• Identify the critical differences between plaza deck assemblies and conventional roofing systems.
• Explain the role and advantages of protected membrane (IRMA) assemblies in plaza deck applications.
• Recognize common plaza deck failure points—including drainage design, slope-to-drain, penetrations, transitions, door sills, and expansion joints—and apply best-practice detailing strategies to minimize moisture-related risks and premature system failure.
• Evaluate plaza deck waterproofing system options (PMMA, STPE, SBS, and hot rubberized asphalt) based on performance characteristics, constructability, and warranty considerations in order to support safe, durable, and watertight plaza deck design.
