Decades ago, diagnosing a slab leak meant tearing up concrete based on rough guesses. Plumbers would bring heavy jackhammers into living rooms, creating clouds of silica dust and destroying expensive tile floors.
The Physics of Acoustic Leak Detection
When municipal water escapes a copper pipe under 60–80 PSI pressure, the turbulent flow generates sound waves ranging from 500 Hz to 2,000 Hz. These acoustic vibrations travel through the wet soil and concrete slab.
Our acoustic geophones utilize ultra-sensitive piezoelectric transducers paired with digital frequency filters. By filtering out background ambient noise like freeway traffic on the I-10 or 210, our master plumbers can hear the exact point of highest sound amplitude, pinpointing the subterranean leak within a 2-inch radius.
