The Three Fundamental Ways Walls Manage Water

  • 1.  The Three Fundamental Ways Walls Manage Water

    Posted 09-29-2022 05:30 PM

    Walls manage water in three fundamentally different ways: storage (mass walls), exclusion (perfect barrier walls), and drainage (drained walls).  While there is no "best" approach to water management - each of these three strategies is entirely valid - it is certainly true that one approach or another may be more appropriate in the context of a specific project with a particular aesthetic, material palette, and performance objectives.  This short course describes the three approaches to water management in walls and explains how water management is best understood as a system as opposed to a feature of any single component or building material.
