How We Detect Hidden Water Leaks

Locating a hidden water leak requires more than simply looking for visible signs of water damage. At Austest, we use a combination of specialist leak detection equipment to accurately investigate concealed and underground water leaks while minimising unnecessary damage to your property.

Depending on the location and type of leak at your Melbourne property, our technicians may use:

Acoustic Leak Detection

Specialised listening equipment can detect the sound of water escaping from pressurised pipes, helping pinpoint leaks beneath concrete, underground and within concealed pipework.

Thermal Imaging

Thermal cameras identify temperature variations that may indicate hidden moisture or leaking pipes behind walls, beneath floors and in other difficult-to-access areas.

Tracer Gas Leak Detection

For difficult-to-locate leaks, a safe tracer gas can be introduced into the pipework. Specialist equipment detects where the gas escapes, helping narrow down the location of small or concealed leaks.

Moisture Detection

Moisture meters help identify elevated moisture levels in walls, floors and other building materials, providing further evidence of where hidden water may be travelling.

CCTV Camera Inspection

Where drainage or accessible pipework needs to be investigated, CCTV cameras can provide a direct view inside the pipe to identify cracks, damage, blockages and other potential problems.

By combining the most appropriate detection methods for the property and suspected leak, our technicians can narrow down the source before unnecessary excavation or repair work begins.

Underground Water Leak Detection

Underground water leaks can be difficult to identify without specialist equipment. Using advanced acoustic leak detection, thermal imaging, tracer gas technology and pipe location equipment, our technicians can accurately pinpoint hidden underground leaks while minimising disruption to your property.

Whether the leak is underground, beneath the garden, within concrete slabs or in an underground water main, we provide fast and accurate water leak detection services to help identify the source to assist with a repair solution.

Common Signs of an Underground Water Leak

Hidden water leaks are not always immediately visible. Warning signs can include unexplained increases in water bills, damp walls or flooring, reduced water pressure, mould growth, water stains and the sound of running water when fixtures are turned off.

If you notice these signs, professional water leak detection can help locate the source before the leak causes further property damage.

Water Leaks Behind Walls and Under Floors

Water leaks can develop inside walls, beneath flooring and within other concealed areas where there may be no obvious visible source. Using non-invasive leak detection equipment, our technicians can investigate moisture and water loss without unnecessary exploratory damage, helping narrow down the source before repairs begin.

Residential & Commercial Water Leak Detection

Austest provides water leak detection for homes, commercial buildings and industrial properties across Melbourne. Whether you’re dealing with a concealed household plumbing leak, underground water main or water loss across a larger commercial site, our technicians use specialist equipment to accurately locate the source with minimal disruption.

What Happens Once the Water Leak Is Located?

Once the source of the leak has been detected, our technicians can provide findings and recommendations to help determine the next steps. Accurately locating the leak before repairs begin can reduce unnecessary excavation, minimise property damage and allow repair work to be targeted to the affected area.

Water Leak Detection FAQs

How do you detect a hidden water leak?

We use specialist equipment such as acoustic leak detection, thermal imaging, tracer gas and moisture meters to investigate hidden water leaks. The most appropriate method depends on the location, pipework and conditions at the property.

What are the signs of a hidden water leak?

Common signs include unexplained increases in water bills, damp walls or floors, reduced water pressure, mould growth, pooling water and the sound of running water when fixtures are turned off.

Can you detect an underground water leak?

Yes. We specialise in locating underground water leaks beneath gardens, driveways, concrete and other difficult-to-access areas using non-invasive leak detection equipment.

Can you find water leaks beneath concrete slabs?

Yes. Depending on the pipework and site conditions, acoustic equipment, thermal imaging and tracer gas can help locate leaks beneath concrete without unnecessary exploratory excavation.

Can you find a water leak without damaging my property?

In many cases, yes. Our non-invasive water leak detection methods are designed to narrow down the source of a leak before excavation or repair work begins, helping minimise unnecessary damage and disruption.

Why has my water bill suddenly increased?

An unexplained increase in water usage can be a sign of a concealed or underground leak. Checking your water meter when no water is being used can help indicate whether water may be escaping somewhere on the property.

How long does water leak detection take?

The time required depends on the size of the property, accessibility of the pipework and complexity of the leak. Once we understand the issue, our technicians can determine the most appropriate investigation method.

How much does water leak detection cost in Melbourne?

Water leak detection costs vary depending on the location of the suspected leak, property size, accessibility and equipment required. Austest can assess your situation and provide advice on the appropriate leak detection service.
