Underground Leak Detection Services in Toronto

Hidden water leaks beneath soil, concrete, and flooring can go undetected for months, causing property damage and inflated water bills. Our non-invasive detection methods pinpoint exact leak locations, minimizing excavation and saving you time and money.

Accurate, Non-Invasive Leak Detection

When leaks remain hidden underground, they cause property damage including mould growth, foundation cracks, soil shifts, and dramatically inflated water bills. Professional detection uses advanced, non-invasive methods to pinpoint exact leak locations beneath your property -- minimizing the need for costly excavation.

Our specialists employ acoustic equipment, microphones, and subterranean water detectors to identify leak noise patterns. Modern technology including ground-penetrating radar, tracer gas systems, and video cameras allows us to locate underground pipes with precision, without tearing up your yard.

Leak Detection FAQ

Look for early signs such as a sudden increase in your water bill, especially when usage has not changed. You can also monitor your water meter -- if it continues moving with all fixtures turned off, that indicates a leak. Structural warnings include concrete cracks, mould, mildew, or soft ground in your yard.
We employ acoustic equipment, microphones, and subterranean water detectors to identify leak noise patterns. Our technology also includes ground-penetrating radar, tracer gas systems, and video cameras for precise underground pipe location without extensive excavation.
Acoustic leak detection is highly precise for underground leaks. It works by identifying leak noise generated when escaping water hits soil, gravel, or pipe surfaces. Combining multiple data points from tracer gas, sensors, and pressure readings enhances accuracy while protecting your property from unnecessary digging.
Common causes include aging materials and corrosion weakening pipes over time, external pressure from soil shifting or nearby construction damaging pipelines, and improper installation or worn joints at connection points.
Yes. Delayed repairs cause major structural damage including foundation weakening, soil erosion, and concrete shifting. Continuous leaks also contribute to high bills and non-revenue water loss, especially if the main water line is affected.
