Water leaks can cause severe damage to a property, leading to high water bills, structural issues, and potential health risks from mould growth. Many leaks remain undetected as they occur within walls, underground, or under concrete slabs. This article explores different water leak detection methods, ranging from traditional techniques to advanced technologies used in Melbourne homes and businesses.

Visual and Physical Inspections
Signs of Leaks in Walls and Ceilings
The first step in detecting a water leak is a visual inspection. Look for signs such as:
- Water stains or discoloured patches on walls and ceilings.
- Peeling paint or bubbling wallpaper.
- A damp, musty smell in certain areas of the house.
When water leaks from a burst pipe behind a wall, it may not always be visible. However, soft or warped plasterboard can indicate moisture buildup inside the structure.
Checking Water Meters
A simple but effective way to detect hidden leaks is by using the water meter. Here’s how:
- Turn off all taps and water-using appliances in the house.
- Check the water meter reading and wait for at least 30 minutes.
- If the meter moves despite no water usage, there is likely a leak in the system.
Modern Leak Detection Methods
Acoustic Leak Detection
One of the most advanced leak detection methods is acoustic detection. This technique uses sensitive microphones to listen for the sound of water escaping from pipes. When a leak occurs, it creates vibrations that can be detected using specialised sensors. This method is highly effective for identifying leaks in underground pipes without excavation.
Infrared Thermal Imaging
Infrared cameras can detect temperature variations in walls and floors, helping to pinpoint hidden leaks. When water seeps into a wall or under tiles, it cools the surrounding material, creating a visible temperature difference. This technique is commonly used for detecting leaks under tiled floors and inside cement structures.
Gas Tracing Methods
This method involves injecting a harmless tracer gas into the pipe system. If there is a leak, the gas escapes and is detected using a gas sensor. This approach is particularly useful for locating leaks in large commercial properties where other methods may be less effective.
Specialised Leak Detection for Different Surfaces
Leaks in Underground Pipes
Detecting leaks in underground pipelines is challenging, but techniques like ground-penetrating radar and acoustic sensors help locate issues without digging. These methods allow technicians to identify leaks in water pipes running beneath driveways, gardens, and roads.
Leaks in Concrete and Cement Structures
Concrete and cement surfaces can absorb moisture from leaks, leading to cracks and structural weaknesses. The best methods for detecting leaks in such structures include:
- Acoustic detection – Identifying leak sounds beneath slabs.
- Infrared imaging – Spotting temperature changes in concrete.
- Pressure testing – Measuring water pressure drops in pipes.
Water leaks can cause severe damage if left untreated. Using modern water leakage detection methods such as acoustic sensors, infrared imaging, and tracer gases, professionals can accurately identify leaks without invasive procedures. Whether you suspect a burst pipe behind a wall or a leak under a concrete slab, early detection is key to preventing costly repairs. If you are in Melbourne and need reliable water leak detection services, consult a specialist to ensure your home remains dry and damage-free.
