Flashing and Moisture Control Best Practices for Masonry Wall Assemblies

Tuesday, June 23, 2026 | 12-1 p.m. Eastern Time
1 LU/HSW

Well-designed masonry walls are among the most durable and resilient building systems and effective moisture control helps them perform at their best. Learn how thoughtful detailing and proper flashing design protect masonry from long-term water damage while supporting healthy, efficient buildings. You’ll explore how water moves through wall assemblies and discover proven strategies to manage it through proper drainage, weeps, vents, and continuity across adjacent systems. We’ll review best practices for selecting and installing flashing materials that enhance durability, energy efficiency, and occupant safety. By applying these techniques, you’ll gain the tools to design and build masonry walls that remain strong, dry, and reliable for generations.
