High-Precision Integrity Testing for Roofing and Waterproofing Membranes
Most waterproofing failures are not a result of "bad products," but rather small, concealed breaches at transitions, penetrations, and seams. Traditional flood testing is often impractical, time-consuming, and carries the risk of overloading a structure or causing interior damage if a leak occurs.
Electronic Leak Detection (ELD) provides a safer, faster, and more accurate non-destructive alternative. By utilizing the electrical insulation properties of waterproofing membranes, we can pinpoint even microscopic breaches—often before the overburden is ever installed.
Technical Methodologies
We utilize both High-Voltage and Low-Voltage testing per ASTM D7877 to ensure 100% coverage across the entire building envelope.
Low-Voltage (Wet) Testing: This method is ideal for large, horizontal surfaces and green roof assemblies. By creating a low-voltage electrical field on a wetted membrane surface, we can follow the directional flow of current to the exact point of a breach. This is highly effective for post-installation QA and can be used for diagnostics during leak investigations.
High-Voltage (Dry) Testing: This method is utilized on dry, exposed membranes, such as TPO roofing membrane. A charged electrode brush is swept over the surface; when a breach or "holiday" is encountered, an electrical arc forms between the brush and the conductive substrate below. High-voltage testing is exceptionally effective for many modern flat/low slope roof assemblies.
