What is Electronic Leak Detection (ELD)?
Electronic Leak Detection (ELD) is one of the best methods to accurately locate leaks. This method of roof leak detection can be used with or without the addition of water – although the equipment used is different, the method is fundamentally the same. Electronic Leak Detection (ELD) is a service that uses non-destructive electronic testing. Honza Group technicians carry out extensive training and all of our operatives are experts in locating and detecting even pin-hole sized leaks.
How does Electronic Leak Detection (ELD) work?
Electronic Leak Detection (ELD) can detect the presence of pin-hole sized defects to within mm accuracy. The technology utilizes the conductive properties (with or without water depending upon site conditions) and identifies defects, which the trained technician is able to utilize, along with their experience, to accurately locate the source of water ingress; in turn providing a detailed and reliable assessment of the condition of your roofing membrane.
When is Electronic Leak Detection (ELD) needed?
Leaks can occur within the roofing/waterproofing assembly. Typically, it was often thought that roofs were “beyond economical repair” as pin-hole sized defects were very difficult to locate / fix, often resulting in short life spans for flat roofs. With ELD, minor defects don’t require a roof replacement since they can detect and locate issues. Accurately locating roof leaks using ELD also means that our experienced technicians are able to locate leak pathways before they are able to cause extensive damage to the membrane and internal structure.
How does it compare to other methods?
Electronic Leak Detection (ELD) is a non-destructive way to test for breaches. Unlike many methods (such as core samples), testing is carried out with no damage caused to your roof. Electronic Leak Detection (ELD) is more accurate, faster and cost effective as compared to other test methods.
Are there any surfaces that ELD doesn't work on?
Any non-conductive surface or an assembly without a conductive layer may not work with Electronic Leak Detection (ELD).
What happens after testing?
Once testing is done, you will be presented with a report detailing locations of breaches.
How much will it cost?
Due to the large number of factors that affect the ability to carry out testing, it is not possible to provide a fixed cost without first discussing your inquiry with one of our consultants. We will provide you with free advice and make recommendations as to the process you should follow for your particular circumstance. Usually, ELD is more affordable than you think.
