Challenges in Modern Plaza Waterproofing Construction

Challenges in Modern Plaza Waterproofing Construction

Plaza and landscaping designs continue to grow more sophisticated as building owners and managers seek to add new features and amenities for their occupants. However, these features present new waterproofing challenges as projects grow more complex. These challenges include addressing drainage around common plaza features like planter walls, incorporating membrane-level drainage at trench drains, or preventing leakage at guard railings. Challenges also arise with unique applications of plaza waterproofing, such as fountains and floodproofing. In this webinar, we will discuss several plaza waterproofing challenges, how to address them, and how to plan for them on future projects.


After attending this webinar, participants will be able to:

  • Understand the importance of plaza waterproofing, including where it applies, different types available, and basic design.
  • Identify plaza features—such as trench drains, site walls, heat trace systems, lighting, and railings—that often require careful detailing or consideration.
  • Learn how these challenges were addressed in several case studies.
  • Recognize unique applications for plaza waterproofing.

Participants will earn 1.0 AIA CES Learning Unit (LU/HSW) for attending the live webinar. Registration is free. Please note that space is limited – email events@sgh.com to join our waitlist if the session is closed when you register.
