Selecting High-Performance Waterproofing Systems for Plaza Decks  

This course provides architects, specifiers, and design professionals with a comprehensive understanding of plaza deck performance requirements and the factors that influence plaza deck waterproofing system success.

Plaza decks are among the most demanding building assemblies, requiring durable waterproofing systems that protect occupied spaces below while withstanding environmental exposure, traffic loads, and long-term service demands. Participants will examine the roles of drainage design, movement accommodation, substrate conditions, and critical detailing in promoting waterproofing durability and service life. The course reviews common plaza deck assembly types – including protected membrane assemblies (PMA), split-slab assemblies, pedestal paver systems, and vegetated roof assemblies – and compares major waterproofing and traffic coating technologies. This comparison highlights capabilities, limitations, and appropriate applications. Attendees will learn to evaluate project-specific conditions and apply practical system selection criteria to identify appropriate waterproofing solutions based on assembly type, constructability, project constraints, and long-term performance objectives. The course also reviews quality assurance strategies, including flood testing, electronic leak detection (ELD), specification development, and construction-phase management.
