Today electronic leak detection (ELD) often replaces flood testing and is being used on waterproofing membranes installed on roofs, plaza decks, pools, water features, covered reservoirs and other roofing and waterproofing applications. The ELD test methods (ASTM D7877) are applicable for membranes made of materials such as polyethylene, polypropylene, polyvinyl chloride, bituminous material, and other electrically insulating materials.

Breaches Can Be Repaired During Testing

Electronic Leak Detection (ELD) testing confirms the integrity of the waterproofing/roofing membrane installation. This method tests 100% of the waterproofing/roofing membrane versus other “hunt and peck” methods. It can reliably test vertical surfaces,
 wall junctions, perimeter details and membrane penetrations.

We can pinpoint breaches during membrane installation so repairs can be made immediately. Breach repairs can be re-tested the same day ensuring minimal impact to your construction schedule. We can tests up to 40,000 sqf per day.

The Most Accurate Results

Other testing methods eventually prove inconclusive on many membrane assembly types. The advanced technology behind JST Development’s testing methods goes much further.
