Electronic Leak Detection

Electronic Leak Detection (ELD) is a type of continuity testing, comparable to a flood test in performance. ELD creates an electric circuit through a non-conductive membrane to find coating film discontinuities that are not readily visible.

Waterproofing Integrity utilise a number of types of electronic leak detection with a view to being fit for purpose and benefits that each offers. an area.

• Detects even the smallest pinholes or punctures invisible to the eye
• Provides instant, exact defect location for efficient repairs
• Avoids long and disruptive flood testing
• Complies with ASTM D7877 and relevant manufacturer warranty guidelines

Large roofs and podiums often hide moisture pathways that conventional testing can’t detect. Electromagnetic scanning generates a dynamic electrical field that maps moisture variations across an entire area, revealing leak paths, saturated substrates, and weak spots with high accuracy. Performed in line with ASTM D7877 principles, it provides a high-resolution overview ideal for complex or multi-layered waterproofing systems.

Leaks can occur, whether that be shortly after works have been completed or years after construction works. This non-destructive investigative scanning technology facilitates the identification of likely leak points in waterproofing membranes or structural elements that can visibly not be seen.

• Detects active leaks and moisture movement with high resolution
• Maps large areas quickly, including complex roof or podium layouts
• Non-destructive and safe for all waterproofing systems
• Produces quantifiable results in line with ASTM D7877 standards
• Suitable for both performance verification and ongoing maintenance
