Protect Your Building from Water Intrusion: Why Knowing Your Wall System Matters

Water intrusion is one of the most expensive and disruptive problems property managers face, often leading to costly repairs, tenant dissatisfaction, and even legal complications. Preventing these issues starts with a critical first step: understanding your building’s wall system.

Most buildings use one of two types of wall systems—barrier walls or drainage plane walls. Knowing which system your building has is essential for implementing the right maintenance strategies and ensuring long-term protection. Here’s what you need to know to safeguard your property.

Barrier Walls: Managing Water at the Surface

Barrier walls are designed to stop water intrusion at the exterior surface, but they lack a secondary line of defense to manage any water that bypasses the outer layer. Any cracks or damage to the surface can lead to significant water intrusion.

Common Issues

Older Masonry Walls: These thick, durable walls were designed to manage minor water intrusion by letting moisture naturally escape over time. While robust, they are becoming less common in modern construction due to the cost of materials and the need for careful maintenance of mortar and joints to prevent leaks.

Modern Barrier Walls: These thinner walls rely on coatings or surface treatments to repel water, making them more vulnerable to damage. Regular inspections for cracks, sealant failure, or surface wear are essential to prevent issues.

Why It Matters

With no secondary line of defense, barrier walls leave no room for error. Minor surface damage can allow water to infiltrate tenant spaces, leading to costly repairs, tenant disruptions, and safety risks. Proactive inspections and maintenance are essential to prevent these issues.

Drainage Plane Walls: A Built-In Backup Plan

Drainage plane walls, also known as cavity walls, are designed with an additional layer of protection—a weather-resistant barrier (WRB) located behind the exterior surface. This secondary layer channels water away from the building’s interior, offering enhanced resilience against water intrusion.

How They Work
  • Weather-Resistant Barrier (WRB): Prevents water from reaching the building’s interior and integrates with other components to create a continuous defense.
  • Flashing: Directs water away from vulnerable areas, such as window sills and roof intersections.
  • Weep Holes: Allow trapped water to escape, ensuring the wall system remains dry.
Common Issues
  • Failures in the WRB due to poor installation or material degradation can lead to water seeping into interior spaces.
  • Repairs often require removing exterior cladding to identify and address the root cause, which can be time-consuming and expensive.
Why It Matters

Failures in the weather-resistant barrier can lead to hidden water damage that’s difficult to detect until it becomes severe. These issues disrupt tenants and threaten the property’s value.
