ZS Solutions

Water Penetration Testing

ZS routinely performs water penetration and air infiltration testing services for windows, doors, curtain walls, and storefront and masonry wall systems.  Using state-of-the-art testing and inspection equipment, ZS professionals have extensive experience performing the testing protocols of the American Architectural Manufacturers Association (AAMA) and the American Society for Testing and Materials (ASTM).

Field testing for water penetration and air infiltration determines the quality of the installation work, ensuring that proper specifications were followed during the construction process. Typically these services are for quality assurance or new building commissioning. On new buildings, we perform baseline water testing to determine if fenestrations (windows/doors/penetrations) are properly flashed and sealed to prevent water and air infiltrations.

We use specialized calibrated spray rack equipment to test for and recreate reported water intrusions and accurately identify failure points in the building envelope. We create a simulated rainfall event in a controlled manner to find the exact source of the water infiltration, a procedure sometimes referred to as forensic water infiltration testing. This systematic approach is the only method recommended, as many times the actual source of water infiltration may originate from the surrounding construction. This information will be accurately documented so proper repair procedures can be executed.  Following the repairs, we typically re-test the areas to determine if the repairs were performed correctly and to verify that the water intrusion has been eliminated. Our testing equipment is highly portable, so we can perform these services anywhere.
