Perth Leak Detectors was recently called to investigate a hidden leak affecting a commercial fire main in Perth. The underground fire main was located beneath a concrete hardstand area, making accurate leak detection essential before any concrete cutting or excavation could begin.
Using specialist leak detection equipment, our technicians traced the underground pipework and accurately pinpointed the location of the leak. This allowed the affected area to be identified before excavation, minimising unnecessary damage to the surrounding concrete and reducing disruption to the commercial site.
The Challenge
Fire mains can run deep beneath concrete hardstands, access areas and other commercial infrastructure. When a leak develops underground, there may be little indication of exactly where the pipe has failed.
Excavating without first locating the leak can result in excessive concrete cutting, unnecessary digging, increased labour costs and disruption to site operations.
For this project, the objective was to accurately locate the underground fire main leak before the concrete surface was disturbed.
Locating the Underground Fire Main Leak
Perth Leak Detectors used specialist leak detection equipment to investigate the fire main and narrow down the source of the water loss.
The investigation included acoustic leak detection and underground pipe location techniques to identify the affected section of the fire main beneath the concrete hardstand.
Once the leak location had been accurately confirmed, the concrete could be cut and removed specifically over the affected area rather than excavating a much larger section of the site.
Leak Found at a Buried T-Piece Connection
Targeted excavation exposed the underground fire main and confirmed that the leak was coming from a buried T-piece connection deep below the concrete surface.
Because the location had already been identified through professional leak detection, excavation could be concentrated directly around the failed connection.
This significantly reduced unnecessary concrete removal and allowed access to the damaged pipework for repair.
Why Accurate Fire Main Leak Detection Matters
Underground fire main leaks can result in significant water loss and increased operating costs. They can also affect the performance of the fire water system and require extensive excavation if the source cannot be accurately identified.
Professional leak detection helps determine the location of the fault before excavation begins, allowing repair contractors to target the affected area.
For commercial and industrial properties, this can help:
- Reduce unnecessary concrete cutting
- Minimise excavation
- Reduce disruption to site operations
- Lower investigation and repair costs
- Prevent continued water loss
- Provide contractors with an accurate location for repair

Frequently Asked Questions
How do you locate an underground fire main leak?
Specialist leak detection equipment can be used to trace underground pipework and identify the location of escaping water. Depending on the site and pipework, techniques such as acoustic leak detection and underground pipe location may be used.
Can you locate a fire main leak beneath concrete?
Yes. Underground leaks can often be accurately located beneath concrete hardstands, driveways and other surfaces before excavation begins.
Do you need to cut concrete to find the leak?
Leak detection is carried out before targeted excavation wherever possible. Once the likely leak location has been confirmed, concrete cutting can be concentrated around the affected area rather than unnecessarily removing large sections of concrete.
What caused the fire main leak on this Perth project?
The leak was identified at a buried T-piece connection located deep beneath the concrete hardstand.
Do you provide commercial leak detection in Perth?
Yes. Perth Leak Detectors provides leak detection for commercial and industrial properties throughout Perth, including fire mains, underground water services and concealed pipework.
