Listen to hidden pipe leaks and find them within inches.
Advanced acoustic correlation technology detects the sound of water escaping under pressure — pinpointing leaks in buried pipes, underground mains, and behind walls without excavation.

Why Leak.ca
Acoustic leak detection done right
Sub-meter accuracy
Gutermann AquaScan correlators pinpoint leaks within 30cm on pipe runs up to 1km. Gold standard for underground leaks.
Non-invasive
No excavation, no drilling, no property damage. We listen through the pipe from surface access points.
Works on any pipe material
Metal, plastic, PVC, PEX — acoustic correlation works on all pressurized pipe materials.
Combined with GPR
We layer acoustic + GPR for underground leaks: acoustic finds the leak, GPR maps the pipe for precise excavation.

Signs you need a professional
Don't wait until minor issues become major losses.
Underground pipe leaks
Buried water mains and service lines can leak for months before surfacing. Acoustic finds them before they become sinkholes.
High water bills
A hidden underground leak can add thousands to quarterly water bills. Acoustic detects the smallest pressurized leaks.
Slab leaks
Water escaping from in-slab pipes creates a sound signature. Acoustic correlation finds it within inches.
Fire-suppression leaks
Pressure loss in fire loops is often caused by buried leaks. Acoustic finds them without discharging the system.
Municipal water loss
Distribution system losses waste millions of litres. Acoustic survey of mains is the most cost-effective detection method.
Compressed air losses
Ultrasonic detection finds compressed air leaks that waste energy. Typical plants save 25-35% on air compressor energy.
How it works
What happens when you call
Simple, transparent, focused on getting you the answers you need.
- 01
Access the pipe
We find two access points on the same pipe — can be at the meter, a cleanout, or an exposed section.
- 02
Place the sensors
Hydrophone or accelerometer sensors are attached to the pipe at each access point.
- 03
Correlate the signal
The correlator measures the time delay of the leak sound reaching each sensor and calculates the precise position.
- 04
Mark and report
The leak location is marked on the surface. You receive a report with findings, sensor data, and recommendations.
Real outcomes
Recent acoustic wins
2 leaks found on 2.4km water main survey
Acoustic correlator survey of aging cast-iron main found two breaks — recovery of 1.2M litres per month after repair.
Underground service line leak at retail plaza
Three underground leaks found on main supply line. Overnight acoustic survey, weekend repairs, 40% water bill reduction.
Compressed air survey saves $8,200/year
Ultrasonic survey of compressed air system at food plant found 12 leaks. Repairs paid for themselves in energy savings within 4 months.

- Will leak detection damage my property?
- No. We use non-invasive technology like thermal imaging, acoustic sensors, and ground-penetrating radar. No drilling, cutting, or demolition required in most cases.
- Does insurance cover leak detection?
- Many policies cover detection costs when water damage is present. We provide detailed reports for your insurance claim documentation.
- How quickly can you respond?
- Same-day response is often available for urgent situations. Regular appointments are typically scheduled within 24–48 hours.
- What if you don't find a leak?
- You receive a comprehensive report confirming no active leaks were detected. This documentation is valuable for insurance, property sales, or peace of mind.
- How does acoustic correlation work?
- Two sensors are placed on the same pipe. When water escapes under pressure, it creates sound. The correlator measures the time difference of the sound reaching each sensor and calculates the exact leak position.
