Water seepage in building walls continues to be a long-time problem in building and facility maintenance. ASTM E2128 is a thorough methodology for the testing of leakage with a special emphasis on determining the cause and not just the symptom. The guide was initially adopted in 2001 and reaffirmed since then to assist engineers, architects, consultants, and maintenance personnel in conducting thorough assessments. It is not a design standard but a diagnostic tool that facilitates well-informed decisions for repairs and preventive actions. The guide prescribes a series of investigative steps, such as examination of design documents, inspection, and controlled water testing. It is important because undetected or misdiagnosed leakage can create the conditions for mold growth, corrosion, structural component deterioration, and indoor air quality degradation. With ASTM E2128, professionals can assure that interventions are targeted and effective.
ASTM E2128 Test Method
| Water Spray Testing | Performed by directing controlled water spray on targeted wall areas for durations defined by site conditions to trace leakage paths. |
| Infrared Thermography | Used to detect temperature anomalies in wall assemblies that indicate moisture infiltration behind finishes. |
| Invasive Probing | Removal of interior finishes or small exterior portions to visually inspect concealed areas for water pathways and damage. |
