Our Underground Leak Detection Process

At AnyLeak.ca, we follow a proven, minimally invasive process to detect and localize your leak:

1. Site Evaluation

We assess your property layout, access points, plumbing design, and symptoms.

2. Pressure and Flow Testing

By testing water pressure and monitoring flow rates, we determine whether water is escaping underground.

3. Acoustic Leak Detection

Using high-sensitivity microphones and correlators, we listen for the sound signature of leaks beneath surfaces—even through concrete, tile, soil, or asphalt.

4. Tracer Gas Detection

We inject a safe, non-toxic gas (hydrogen/nitrogen mix) into your pipe system. When the gas escapes through a leak, we detect its location precisely with handheld sensors.

5. Thermal Imaging and Moisture Mapping

For slab leaks, radiant heat system failures, or indoor moisture concerns, we use thermal cameras to locate water paths and pinpoint leak zones without breaking into the floor.

6. Reporting and Repair Support

We provide a detailed report with:

• Source confirmation
• Supporting images or thermal scans
• Recommendations for repair
• Third-party contractor coordination (if requested)

Underground Leak Detection for Residential Properties

We frequently assist homeowners and strata councils facing issues such as:

• Yard irrigation leaks
• Main water line breaks from curb to meter
• Leaks under driveways, patios, or lawns
• Slab-on-grade leaks in radiant heat or copper lines
