Roof membrane on building on Tamaki Drive in Auckland

Leak detection systems for new builds and renovations.

Talk to us before starting your project.

By including leak detection in your building timeline and/or architectural specifications, we can ensure the other trades on your build know what’s required.

No one likes a leaky building, least of all us.  At ILD, we use state of the art technology called EFVM to locate leaks.

ASTM 7877 Electronic Methods for Detecting & Locating Leaks in Waterproofing Membrane (Electric Field Vector Mapping EFVM®)

EFVM produces a precise result.

We can pinpoint leaks exactly to ensure no leak goes undetected.

It has a limited impact on your design.

EFVM doesn't affect the structure of a building. There's no need for reinforcing.

It gives us the ability to retest easily.

Retesting is straightforward and won't cause delays to the building schedule.

It’s flexible.

EFVM can be used in a variety of areas, including garden roofs, parking garages and pools.

How we work with architects and builders

1. Send us your project specifications

Fill in our comprehensive build a quote form with your project details, including what parts of your site need to be tested and the membrane you’re using. You can also upload your drawings. This will enable us to measure, offer advice and send you a quote.

During this process, we can answer any questions you may have, including:

  • How to incorporate membrane into your drawings

  • Which process is best for testing the membrane – flood or electronic

  • How to ensure you're meeting your local council's regulations around waterproofing testing (if applicable)

If you’re keen to progress, ILD’s requirements will be incorporated into your building programme.

2. We’ll work together on site

Building starts. We’ll work with you/the project manager/the water-proofer to sort out a plan for when testing will happen. 

Note: This timing is contingent on whether or not mesh is required (this is dependent on the type of substrate). 

For non-conductive substrates such as plywood or insulated roofs, mesh is required. Your waterproofer or builder will need to lay the mesh before testing can happen. 

For conductive substrates such as concrete, mesh isn't required and testing can be completed after the membrane is installed.

3. We’ll send you a report

After testing is completed, we’ll provide you with a report including details on any leaks or workmanship faults.

This report will include CAD drawings, picture documentation and written analysis detailing the locations of the breaches.

If leaks are detected, we can easily retest the membrane after they've been fixed.

‘We regularly use ILD for all our leak testing. They consistently meet council requirements and are easy to work with.’
