How Radiometric Infrared Detection Solves Slab Leaks
More than 70% of residential slab leaks in Washington State occur on hot water copper lines. Because hot water under continuous 50–70 PSI pressure radiates heat through concrete and finished floor materials, high-sensitivity FLIR infrared cameras can visualize the subterranean thermal plume with extreme precision.
When viewed through a thermal camera calibrated for subtle temperature differentials (down to 0.05°C), a broken hot water pipe presents as a vivid radiant heat signature—clearly delineating the pipe line and the expanding bloom where hot water is soaking into sub-slab gravel.
Advantages of FLIR Thermal Leak Audits
- Instant Visual Confirmation: You can see the leak with your own eyes on our technician's high-definition display.
- Zero Floor Damage: Works seamlessly through porcelain tile, solid hardwood, vinyl plank, carpet, and exposed concrete.
- Subterranean Pipe Mapping: Verifies the orientation of under-slab manifolds and branching copper runs.
- Moisture Evaporative Cooling Detection: For cold water line leaks, thermal imaging captures subtle evaporative cooling footprints where evaporating water creates colder zones.
