Specialist Water Leak Detection for Complex Commercial and Civil Problems

When water escapes in a commercial, industrial or multi dwelling environment, the consequences can be severe. Flooding, asset deterioration, operational interruptions and safety compliance risks can appear quickly. LeakTech specialises in locating high value, large scale and technically complex leaks that aren’t easy to diagnose.

Our water leak detection team uses advanced acoustic, thermal and gas tracing technology to locate leaks with accuracy across commercial buildings, multi site organisations, industrial facilities, civil infrastructure and fire line networks. From underground pressure failures to concealed internal leaks that impact entire structures, we help protect some of Queensland’s largest and most sensitive assets.

While we do assist with residential leak detection, our primary focus and expertise lie in commercial and civil environments where accuracy, speed and non-invasive confirmation are essential for costly and high volume water systems.

Commercial and Civil Leak Detection Services

Below is the full range of leaks we locate, listed from highest commercial value through to smaller residential scale issues. This reflects the priority of work we undertake and the environments where our expertise delivers the greatest long-term savings.

Complex commercial water leak detection and industrial leaks

Commercial and industrial water systems operate under higher pressure, longer distances and more complex layouts than residential networks. Our specialists locate leaks in:

Fire mains and hydrant systems
Multi level risers
Plant rooms and pump systems
Large diameter pipelines
Basements, car parks and carwash drainage
Long commercial driveway or roadway pipe runs
Service corridors and suspended ceiling systems

Accuracy is critical in these environments. Every misdiagnosed metre can increase repair costs or lead to unnecessary downtime. Our technology pinpoints leak locations quickly so facility managers, plumbers and subcontractors can repair the issue immediately.

Multi dwelling leaks

Apartments, townhouses and large body corporate complexes often share interconnected pipework. One undetected leak can affect multiple residents, common areas or shared services. We specialise in:

Stack line leaks
Combined pressure system faults
Intermittent leaks across multiple levels
Shared line isolations
Confined space and difficult access detection

We work directly with building managers, strata committees and plumbing subcontractors to ensure minimal disruption and fast diagnosis.

Hidden internal leaks

Internal leaks cause significant damage long before visible signs appear. In commercial buildings, this includes wall cavities, internal risers, ceiling voids, office fitouts and service ducts. Using non invasive tools, we locate:

Leaks behind walls and internal linings
Ceiling leaks above commercial tenancies
Hidden slab leaks beneath office floors
Leaks within suspended ceilings or service risers

These leaks often trigger mould, acoustic issues, damage to technology and loss of tenancy quality. Early detection is essential for compliance and cost control.

Underground pressure leaks

These are common across commercial driveways, concrete slabs, loading docks, car parks, irrigation networks and civil pathways. They are extremely difficult to locate without specialist tools. Our equipment identifies:

Leaks under concrete and bitumen
Deep underground burst lines
Pressure issues beneath paved or landscaped areas
Leaks running along long commercial pipe lengths

Our precision reduces excavation costs and prevents unnecessary destruction of commercial surfaces.

Roof and rain leak detection

Commercial roof leaks are often misdiagnosed because the water entry point rarely matches the internal damage. We use thermal imaging and moisture mapping to locate:

Flashing and membrane failures
HVAC penetration leaks
Stormwater ingress
Faulty commercial roof systems
Multi level building water tracking

Accurate detection prevents repeated patchwork repairs and eliminates guesswork.

Irrigation and garden leaks

Large commercial landscapes and multi dwelling communal gardens can develop hidden irrigation issues that waste significant water. We detect:

Underground irrigation line leaks
Faulty valves and solenoids
Subsurface water pooling
Leaks affecting lawns, median strips and landscaped areas

Toilet cistern leaks

Cistern leaks in commercial facilities often cause major water wastage across multiple stalls or levels. We detect:

Silent cistern leaks
Faulty valves
Constant refilling issues
Undiagnosed water loss in high volume buildings

Tap and fixture leaks

While simple tap and fixture issues can often be managed by plumbing companies, we assist when:

The leak source is unclear
Previous attempts have failed
Moisture is appearing in unexpected areas
Multiple fixtures are affected
The issue forms part of a larger leak detection job

For basic residential tap leaks, a plumber may be sufficient. For complex or misdiagnosed leaks, LeakTech is the best first call.

Residential Leak Detection
(When It Becomes Complex)

Most simple household leaks can be repaired by a plumber. However, when the source is hidden, intermittent or difficult to locate, LeakTech is often called in.

Examples include:

Hot spots on floors with no obvious cause

Unknown internal moisture

High water bills without visible leaks

Other exploratory work has been unable to pinpoint the issue

In these cases, our specialised equipment and experience allow us to find what others cannot.

Planning a Bathroom Reno or Floor Upgrade?
Test for Concealed Moisture Before You Tile or Lay Flooring.

Floor that looks dry from the surface can be hiding dampness from a slow leak, poor waterproofing, or a previous repair that never fully resolved. Laying new tiles or bathroom fitting over the top of hidden moisture can compromise the whole project from the start.
Moisture can cause adhesive to fail, grout to crack, tiles to lift, or timer to swell or warp, causing your new bathroom to look worn and need repairs prematurely. A professional moisture and leak detection scan before any flooring or tiling work begins identifies concealed moisture and locates the source, allowing for targeted repairs and supporting long-lasting renos.

This combination ensures the most reliable outcome for complex leak scenarios.

Detecting Usage Issues in Commercial and Multi Site Properties

Water usage spikes can be extremely expensive in commercial contexts. We analyse:

Daily, nightly and seasonal usage
Pressure fluctuations
Commercial hot water systems
Irrigation behaviour
Roof or rainwater intrusion
Multi dwelling shared line consumption

This helps identify whether the leak is internal, underground or external and prevents prolonged financial loss.

Frequently Asked Questions

What exactly counts as a water leak?

A water leak is any unintended escape of water from a pressurised plumbing system, fixture, fire line, commercial pipeline, irrigation network or underground service. This includes silent pressure leaks, faulty valves, burst mains, cracked industrial lines and leaks concealed within walls, floors, plant rooms or service risers. In commercial or multi dwelling environments, even a small leak can lead to significant operational and structural impacts, which is why accurate detection by a specialist is essential.

Is every increase in my water bill a sign of a leak?

Not always. Usage may rise due to irrigation, increased occupancy or seasonal changes. However, an unexplained or sudden spike often indicates an internal or underground leak, especially in commercial, multi site or industrial environments where systems are larger and more difficult to monitor. Our leak detection specialists analyse usage patterns, pressure behaviour and on site test results to determine whether a leak is present and where it may be occurring.

How accurate are professional leak detection methods?

Modern leak detection combines advanced acoustic listening tools, thermal imaging, correlation technology, moisture mapping and tracer gas systems. These methods allow our team to pinpoint leaks with a high degree of accuracy, even in environments involving concrete slabs, long commercial lines, buried pipelines or multi level buildings. This precision reduces repair costs and prevents unnecessary demolition or exploratory works.

Can rainwater entry be mistaken for a plumbing leak?

Yes. Wind driven rain, roof membrane failures and stormwater ingress can produce symptoms identical to internal plumbing leaks. This is common in commercial buildings with complex roof structures or large drainage networks. Our team uses thermal imaging, moisture mapping and dedicated rain leak detection techniques to distinguish between plumbing leaks and weather ingress so the correct repair path is taken from the start.

Do you provide leak detection for commercial, industrial and civil properties?

Yes. LeakTech specialises in commercial water leak detection across warehouses, factories, retail centres, office buildings, multi dwelling complexes and civil infrastructure. These environments often involve high pressure systems, long underground lines, fire mains, sewer rising mains and extensive pipe networks that require specialist equipment and experienced technicians.

Will leak detection damage my property?

No. LeakTech uses non-invasive methods including thermal cameras, acoustic sensors and tracer gas technology. These tools allow us to identify leak locations without cutting walls, lifting flooring or excavating unnecessarily. This approach is especially important in commercial and multi dwelling environments where disruption can be costly.

What if the leak is underground or outside the building?

Underground and external leaks are common, particularly in commercial car parks, concrete driveways, landscaped areas, buried services and civil pipeline networks. We use a combination of acoustic detection, correlation technology, pressure testing and tracer gas to locate leaks beneath soil, turf, concrete, asphalt and paved surfaces with precision.

How long does a typical leak detection inspection take?

Residential inspections generally take one to two hours depending on access and complexity. Commercial, industrial and civil inspections may require additional time due to system size, isolation requirements, safety procedures and the need to test multiple sections or levels. Our specialists work efficiently to deliver clear results as quickly as possible without compromising accuracy.

Does LeakTech repair leaks once they are detected?

LeakTech focuses solely on locating leaks with precision. We do not perform repairs. Once we identify the exact source of the problem, we provide a clear summary so your preferred plumber, maintenance contractor or builder can carry out the repair confidently and without unnecessary exploratory works.
