How to Find Leaks in Waterproofing Membranes

Detecting water leaks in waterproofing membranes with pinpoint accuracy has just become a reality here in NZ thanks to the latest electronic field mapping leak detection service.

Flood testing used to be the only effective way to determine if/where a membrane was leaking… but there are plenty of downsides to using this method of leak testing. What if you have a roof surface area of 1000 sqm? That’s a lot of water to flood test!

Electronic advances in NZ have now made is much easier to find a membrane leak.

New and Proven. Electronic field mapping will detect any breaches in either new or old membranes with pin point accuracy (excluding black butanol), by ‘charging’ the surface area with low voltage, thus creating a potential difference on conductive and non-conductive surfaces like decks, which is earthed or grounded. Water is still used as the conductive medium with this method, but there is no need to flood the area. The advanced leak detection device then reads the electronic flow across the surface and will pinpoint any ‘vectors’ (where the leak(s) is occurring).

This is an excellent option with new installations to assure the client of quality workmanship before signing off on the job.

What type of applications can this method be used for?

Leaks under a roof garden, Roofs with ballast, Tiled decks, Leak detection through paving stones, Insulated and non-insulated roof structures, Structural decks, Swimming pools, Vertical walls and many more.

For those of you in the construction game, you know perfectly well how hard it can be to track down a leak in a building you’ve built… especially under flat roofs. The problem with water is that it takes the path of least resistance which means the leak and the leak source can be up to 30 meters apart (ugly)!

What if there’s a large building over the top of an underground car park leak? This would normally take lots of trial and error, ‘theories’ from multiple contractors you have to pay for, and your time to nut out the leak penetration point. No more! These types of leaks can now be ‘express’ detected using electronic leak mapping.

Got a waterproofing warrantee that’s about to expire?

Get a check up for any pin holes or breaches in the membrane before the expiration date!

This new method is a simple and logical way test new installations for leaks before covering the membrane over, and finding tricky leaks… and there is only one company with the exclusive rights to this high tech leak detection technology in New Zealand, and the field mapping technicians are internationally trained.
