Understanding Electric Field Vector Mapping

Electronic Leak Detection (ELD) is a cutting-edge technology redefining the art of integrity testing and leak detection in low-slope roofing and waterproofing systems.

Electric Field Vector Mapping pinpoints breach in horizontal roof membranes by tracing the flow of an electric current across a wetted membrane surface. Manufacturers, contractors, and specifiers in the United States have rapidly adopted Electronic Leak Detection.

How Electronic Leak Detection with Electric Field Vector Mapping Works

Setup
A wet (not flooded) roof membrane creates a conductive surface. A wire loop is placed around the test area, with one lead from a pulse generator connected to this loop and another lead connected to the roof's structural deck.
EFVM is one of the most advanced and effective methods for flat roof leak detection. It works by applying an electrical current across the roof membrane to identify any breaches. When combined with our roof leak detection equipment, EFVM can quickly and precisely locate any points of water entry for immediate repairs and retesting to confirm a watertight installation.
Current Flow
When there's a breach in the membrane, the electric current flows across the conductive surface, passes through the breach, and connects to the grounded deck below, completing the circuit.

Detection
Using two probes connected to a receiver, technicians trace the direction of the electric current flow, which leads them to the exact location of the membrane breach.

Key Advantages of Vector Mapping

  • Efficient and cost-effective testing for horizontal surfaces
  • Precise breach detection, including pinhole and capillary action leaks
  • Much more reliable results than traditional flood testing
  • Immediate identification of defects for rapid repair
  • Breach-Free Certification issued after successful repairs and retesting

Applications and Compatibility

Electric Field Vector Mapping testing is ideal for:

  • Uninsulated low-slope roofing and waterproofing systems
  • Green roof installations prior to overburden placement
  • IRMAs and PMRs with conductive structural decks
  • Plaza decks and podiums
  • Quality assurance verification
  • Warranty validation requirements

The system works with most membrane types, excluding metal-coated and carbon-black EPDM membranes. All testing complies with ASTM Standard D7877 for electronic leak detection.
