Concrete Slab Leak Detection Perth

Water leaks beneath concrete slabs can be difficult to locate and may continue unnoticed until they cause rising water bills, damp flooring, structural damage or other problems around the property. Perth Leak Detectors provides professional concrete slab leak detection throughout Perth, using advanced non-invasive technology to accurately locate concealed water leaks before unnecessary excavation begins.

With over 25 years of industry experience, our technicians use specialist leak detection equipment to investigate water loss beneath concrete floors, slabs, driveways and other hard surfaces across residential, commercial and industrial properties.

What Is a Concrete Slab Leak?

A concrete slab leak occurs when water escapes from pipework located beneath or within a concrete slab. Because the pipe is concealed, there may be no immediately visible indication of where the leak has occurred.

Instead, the first signs may include unexplained water usage, damp areas, warm sections of flooring, reduced water pressure or water appearing around the edges of the slab.

Accurately locating the affected section of pipe before excavation is essential to minimise unnecessary concrete cutting and property damage.

Signs of a Water Leak Beneath Concrete

Common signs that may indicate a slab leak include:

• Unexplained increases in water bills
• Water meter movement when fixtures are not being used
• Damp or wet flooring
• Warm areas on the floor
• Mould or musty odours
• Reduced water pressure
• Water appearing around the edge of a concrete slab
• Cracking or movement around paved or concrete areas
• The sound of running water when taps are turned off

If you notice these signs, professional leak detection can determine whether concealed pipework beneath the slab is responsible.

How Do We Locate Leaks Beneath Concrete?

There is no single detection method suitable for every slab leak. Perth Leak Detectors assesses the property and selects the most appropriate technology based on the pipework, location and suspected type of leak.

Methods may include:

Acoustic Leak Detection

Specialist acoustic equipment can detect the sound and vibrations created when pressurised water escapes from damaged pipework. This can help pinpoint leaks beneath concrete without initially cutting into the slab.

Thermal Imaging

For concealed hot water leaks, thermal imaging cameras can identify temperature differences created by escaping hot water beneath floors and concrete surfaces.

Tracer Gas Leak Detection

Tracer gas can be introduced into suitable pipework to locate particularly difficult or small leaks. The gas escapes through the damaged section and can be detected above the surface using specialist equipment.

Pressure Testing

Pressure testing can assist in determining whether a section of pipework is losing pressure and requires further investigation.

By combining appropriate detection methods, the location of a concealed leak can be narrowed down before repair work begins.

Can a Slab Leak Be Located Without Digging?

In many cases, the investigation can be carried out without exploratory excavation.

The purpose of professional slab leak detection is to identify the likely location of the damaged pipe before concrete is cut or removed. Once the location has been confirmed, any excavation required for the repair can be targeted to a much smaller area.

This can help reduce:

• Unnecessary concrete removal
• Property damage
• Labour requirements
• Repair costs
• Disruption to the property

Residential Concrete Slab Leak Detection

Slab leaks can occur beneath homes, garages, patios, driveways and other concrete areas. For homeowners, accurately locating the problem before repairs begin can prevent large sections of flooring or concrete from being unnecessarily disturbed.

Perth Leak Detectors investigates concealed water loss throughout residential properties across the Perth metropolitan area.

Commercial & Industrial Slab Leak Detection

Concrete slab leaks can also affect commercial buildings, warehouses, workshops and industrial facilities where extensive concrete hardstands and floors can make underground pipework difficult to access.

Accurate leak location allows contractors and facility managers to target the affected area while minimising disruption to surrounding operations.

Frequently Asked Questions

How do you find a water leak under a concrete slab?

We use specialist leak detection methods such as acoustic listening equipment, thermal imaging, tracer gas and pressure testing to investigate concealed pipework and accurately narrow down the leak location.

Can you detect a slab leak without breaking the concrete?

In many cases, yes. Non-invasive leak detection equipment can be used to identify the likely location before concrete cutting or excavation begins.

What are the signs of a concrete slab leak?

Common signs include unexplained water bills, damp or warm flooring, water meter movement, reduced pressure, mould, moisture around the slab and the sound of running water when fixtures are turned off.

Can thermal imaging locate a slab leak?

Thermal imaging can be particularly useful for hot water leaks because escaping hot water may create detectable temperature differences across the floor or concrete surface.

Can tracer gas locate leaks beneath concrete?

Tracer gas can be effective for difficult-to-locate leaks beneath concrete. The gas escapes through the damaged section of suitable pipework and is detected at the surface using specialist equipment.

Do you provide concrete slab leak detection across Perth?

Yes. Perth Leak Detectors provides slab and concealed water leak detection for residential, commercial and industrial properties throughout the Perth metropolitan area.
