Electronic Leak Detection

Water ingress can be difficult to trace, especially on flat roofs where moisture can travel long distances before becoming visible internally. Our Electronic Leak Detection (ELD) service provides a fast, reliable, and non-destructive method of locating even the smallest breaches in a waterproofing membrane—saving you time, disruption, and costly investigative works.

Using advanced testing equipment, we pinpoint the exact location of leaks so repairs can be carried out quickly and effectively, without the need to strip large sections of roofing.

Typical Issues We Identify

• Punctures in membranes
• Poorly sealed laps
• Mechanical damage
• Failed detailing around pipes, skylights, and edges
• Hidden cracks below surface finishes
• Installation defects
• Damage caused by foot traffic or maintenance work

Whether it’s a small puncture or a major membrane failure, our systems provide the clarity you need.

Electronic Leak Detection is a specialist testing method designed to locate failures in flat roof waterproofing systems such as:

• Single ply membranes
• Liquid roofing systems
• Bituminous felt roofs
• Green roofs
• Warm roofs & cold roofs
• Podium decks & balconies
• Inverted roofs

The system works by applying a safe electrical current across the surface of the roof. Where the waterproof layer is compromised, the current travels through the membrane and is detected with precision instruments—revealing the exact location of the defect.

Where ELD Is Used

Our electronic leak detection services are suitable for:

• Residential properties
• Commercial and industrial buildings
• New-build construction sites
• Property management & insurance investigations
• Schools, hospitals & public buildings
