Electronic Leak Detection (ELD) inspection of Bitumen of PVC roofing.

Advanced electronic testing to assess roofmembrane integrity and locate potential defects.

ELD-scanning is one of the most comprehensive methods for investigating the integrity of bituminour or PVC roofmembrane. We use several specialised testing devices and select the appropriate method according to the roof construction, inspection requirements and site conditions.

The inspection combines electronic scanning with visual roof survey. It is designed to identify electrically datactable defects and potential breaches in the waterproofing membrane, including penetrations and other critical roof datails.

ELD testing can also be used to verify the integrity of newly installed  or renovated roofing as part of the construction quality -assurance and handover process. Successful testing requires a suitable roof construction and testing arrangement. ASTM D7877 and ASTM D8231 address electrical methods for detecting leaks in waterproofing membranes. The  applicable standard and testing procedure must be selected according to the specific system androof construction.

ELD inspection is particularly suitable when:

• A roof is leaking, but the source has not been identified
• A more detailed assessment of the roof membranes integrity is required
• Potential defects need to be located before repair work is planned
• Independent quality assurance is required for a new or renovated roof, where the construction is suitable for the selected ELD method  

Following the inspection, you receive a photographic report documenting the findings, the locations of identified defects and recommendations for further action.
