Non-Destructive Acoustic & Thermal Leak Detection

Concealed pipe leaks beneath concrete slabs or inside finished walls can cause extensive structural damage if left undetected. Our technicians utilize ultrasonic acoustic locators, thermal imaging cameras, and tracer gas equipment to pinpoint leak locations without destructive digging.

Once identified, we provide precision spot repair options, including pipe bypass re-piping or localized slab excavation to restore water supply integrity.

Leak Detection Technologies We Use

  • Ultrasonic Acoustic Sensors: Listening to sound frequencies generated by pressurized sub-slab pipe pinholes.
  • Infrared Thermal Imaging: Detecting temperature anomalies caused by hot water slab leaks.
  • Digital Pressure Drop Testing: Verifying system tightness across long domestic supply runs.
  • Non-Destructive Spot Locating: Marking exact repair locations to minimize flooring disruption.
