Water intrusion assessments are designed to investigate and determine the source of water intrusion through wall systems, doors, windows, skylights and curtain walls. Errors in construction/repair work and/or compromised building materials may lead to water intrusion from the exterior (rain). When residents or business owners experience water intrusion and subsequently enact remediation or repairs to buildings materials, it is often recommended to have the areas of repair tested for water intrusion prior to repair completion.
It is crucial to accurately identify the root cause of an active water intrusion. Many times, AMRC observes the removal and reconstruction of interior building materials without confirmation of the source of the leak. The time and expense to perform an initial, well-focused evaluation may save the building owner from making unnecessary repairs and assist in preventing the reoccurrence of the leak.
Using elements of the ASTM E1105 (Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Walls, by Uniform or Cyclic Static Air Pressure Difference) and ASTM E2128 (Standard Guide for Evaluating Water Leakage of Building Walls) water testing methods, AMRC consultants conduct water testing.
The ASTM guide addresses the performance expectations, service history of a wall system, various components of a wall, and the interaction between these components and adjacent construction. The guide provides methodology for a systematic approach to an evaluation, including providing details on the initial evaluation, reviewing the service history, identifying the physical symptoms, visually inspecting reported intrusions, developing a hypothesis, recreating leaks while simulating normal rainfall, tracing and correlating intrusions, verifying the hypothesis, providing a final analysis, and accurately reporting through documentation.
