Verifies Green Roof Membranes Prior to Installing Overburden
Pinpoints Leaks in Roofing & Waterproofing Membranes
Ideal for Warranty Verification
Locates Breaches Too Small to Detect Visually
Electronic Leak Detection: Less Expensive, Safer, Faster, and More Accurate Than Flood Testing

Electronic Leak Detection (ELD) is a cutting edge technology that is redefining the art of leak detection and quality assurance in low-slope roofing and waterproofing systems. ELD eliminates the dangers and potential damage inherent in traditional flood testing. Unlike the interpretive process of water, flood, infrared, or nuclear testing, ELD detects membrane faults directly. It is ideal for quality and warranty assurance needs and for leak detection in all low-slope roofing systems in which the membrane is not electrically conductive and the deck can be electrically grounded. Even pinhole leaks invisible to the naked eye can be pinpointed, and repairs can be made on the spot and immediately retested to ensure watertight results.

High Voltage Electronic Leak Detection: High Voltage ELD is performed on dry horizontal and/or vertical surfaces using a very small current at relatively high voltage for safe and reliable testing. One lead from the portable current generator (charger) is grounded to the roof or structural deck (either metal or concrete). The other lead is attached to one of several available electrode brushes made with highly conductive metal bristles. As the technician “sweeps” the brush electrode over the surface of the membrane or flashing, electricity will flow through any breach or gap, completing an electrical circuit between the brush and the deck. Where there are no faults in the waterproofing system, the membrane or flashing acts as an insulator and prevents the flow of current to the deck. Download our free specifications

High Voltage ELD vs Low Voltage Vector Mapping: Both High Voltage ELD and Low Voltage Vector Mapping can be employed on most roofing and waterproofing membranes. However, because the High Voltage brush sensor must make direct contact with the membrane, roofs with overburden (vegetation, pavers, ballast, etc.) must be tested with Low Voltage Vector Mapping. Neither method can reliably inspect black EPDM membranes, which contain carbon black and are therefore electrically conductive.

High Voltage testing is often faster, simpler and less expensive than Low Voltage Vector Mapping, which requires more setup as well as constant wetting of the membrane. The interpretive nature of Low Voltage testing can require more inspection time, particularly if multiple breaches are present. Both techniques are safe, cost-effective and highly reliable, allowing problem areas to be quickly marked, repaired, and re-tested.

ELD Fusion®: Traditional Low Voltage Vector Mapping is an accurate and reliable technique for integrity testing on large, wide open areas. But standard low voltage methodology does not typically test many of the areas that require the most careful and conscientious work – parapets and curbs, flashings, and transitions from horizontal to vertical surfaces. Now you can get virtually 100% testing on your work with ELD Fusion®, our unique combination of High and Low Voltage Electronic Leak Detection methodologies. ELD Fusion combines traditional Low Voltage Vector Mapping (wet testing) on large horizontal areas with High Voltage ELD (dry testing) on vertical surfaces, transitions, and other areas not typically tested with the low voltage technique. ELD Fusion gives you 100% coverage – and 100% peace of mind that your membrane will be leak free. Download our free specifications

High Voltage ELD benefits:

      • Pinpoints membrane defects for efficient repair
      • Repairs can be immediately re-tested
      • Detects all breaches, even pinhole and capillary action leaks
      • Sloped roof systems and flashings can be efficiently tested
      • Enables direct (non-interpretive) detection of membrane breaches
      • Suitable for both horizontal and vertical surfaces
      • Less expensive, faster, safer, and more reliable than flood testing

High Voltage ELD applications:
