What is Electronic Leak Detection (ELD)?

Electronic Leak Detection (ELD) works by separating two opposing electrical fields with an insulator (membrane). A breach is located when the two opposing electrical fields meet via a hole in the membrane. Benefits of Electronic Leak Detection (ELD) are:

  • Accelerates construction schedule

  • Locates breaches undetectable to the naked eye with pin-point accuracy.

  • Non-Destructive

  • Cost-Effective

  • Effective on a variety of roofing/waterproofing applications including various slope types.

  • Environmentally friendly- minimal to no water required.
