High Voltage Electronic Leak Testing

(Dry Conditions)

Depending on the site conditions, high voltage (dry method) Electronic Leak Detection testing could be the best option when trying to determine if/where you have breaches. Honza Group, Inc. will consult with you to see if the High Voltage method of testing makes the most sense for your project.

Set-Up

The testing unit acts as a power supply and is connected to the conductive deck which acts as one of the electrical plates/fields. This is usually done by connecting to a conductive penetration (for example drain bowl, davit, etc.).
The electrode brush is also connected to the testing unit which acts as the second electrical plate/field.
The electrode brush must be able to make contact with the roofing/waterproofing membrane in order for testing to be completed. Obstructions such as materials, equipment, and debris can inhibit testing if not cleared from the area.

Testing

The electrode brush is swept across the entire membrane.
If the electrode brush encounters a breach during the test, the circuit is completed, and an audible tone alerts the technician.
The area of concern is swept again in order to pinpoint the exact location of the breach.
Once the breach is located, it is marked on the membrane, photographed, and cataloged for reporting purposes.

Reporting

We generate and submit a detailed report of our findings, that includes general project information, noted site conditions (with photographs), breach photographs and measured locations. A digital drawing is submitted with the report that highlights the area(s) tested, with all breach locations plotted.

BUT WHY HIGH VOLTAGE AND NOT LOW VOLTAGE?

Both methods of testing are equally effective. Job site conditions ultimately dictate which method of Electronic Leak Detection should be utilized. From a practical standpoint, High Voltage is used when the area to be tested is dry. There are some site conditions that limit the effectiveness of High Voltage testing.
