Pipeline & Water Network Leak Detection
Over 20 years online have taught us something: quotes are needed fast. That's why we deliver a proposal within 1 hour. Use our service forms for best results.
The Hidden Cost of Leaks
An undetected leak, no matter how small, can become a serious problem. It represents constant resource loss, increases operating costs, and can cause severe structural damage to foundations, pavements, and terrain through subsurface erosion.
At Cartomex, we specialize in precise, non-invasive leak location using multiple technologies. Finding the exact leak point saves you time, money, and avoids unnecessary excavation.
Our Detection Methods
Non-Invasive Surface Detection
🎧 Acoustic Ultrasound Detection
Every leak in a pressurized pipe generates a characteristic sound. We use high-sensitivity ground microphones and amplifiers that filter ambient noise. The leak is located at the point of maximum sound intensity.
Best for: Metal pipes, pressurized water mains, large leaks
💨 Tracer Gas Detection (Hydrogen)
Our most precise method. The pipe is emptied and filled with a safe, non-toxic gas mixture (hydrogen/nitrogen). Hydrogen—the smallest molecule—escapes through any crack and rises to the surface where our sensors detect it.
Best for: PVC/plastic pipes, small leaks, pinpoint accuracy
🌡️ Infrared Thermography
Water or steam leaks alter surrounding surface temperature. High-sensitivity thermal cameras identify these anomalies as "islands" of different temperature, revealing leak locations and affected areas.
Best for: Heating systems, large area surveys, HVAC
📡 Ground Penetrating Radar (GPR)
GPR detects the consequences of leaks in the subsurface: moisture zones, erosion patterns, cavities, and sinkholes. It confirms the affected area and identifies secondary damage from long-term leakage.
Best for: Confirming damage extent, locating voids, mapping pipe routes
Internal Inspection (CCTV)
Once we locate a leak from the surface, we can inspect the pipe interior to identify the exact cause and assess overall pipe condition:
- Push Cameras: For pipes 100mm to 300mm diameter, up to 120m length
- Robotic Crawlers: For larger pipes, self-propelled with 360° camera
- Borescopes: For access through small openings (as small as 6mm)
After finding an anomaly with the camera, we use a 512 kHz locating transmitter to mark the exact surface position above the problem—enabling surgical repairs.

Frequently Asked Questions
How accurate is leak detection?
With tracer gas, we can locate leaks to within centimeters. Acoustic methods typically locate leaks within 0.5-1 meter. This precision allows for surgical repairs, minimizing excavation and disruption.
Can you detect leaks in plastic (PVC) pipes?
Yes. While acoustic methods work best on metallic pipes, our tracer gas technique works on any pipe material including PVC, HDPE, and concrete. We select the appropriate method based on your pipe type.
Do you need to shut off water service?
For acoustic detection, the line should ideally be pressurized and flowing. For tracer gas, we need to isolate and depressurize the section being tested. We coordinate with you to minimize service interruption.
What causes most pipeline leaks?
Common causes include corrosion (metal pipes), ground movement/settlement, root intrusion, poor joint connections, and age-related material degradation. Our CCTV inspection service can identify the exact cause once the leak is located.
