Ground Microphone Surveys

Once correlation has placed a leak within a metre or two, a ground microphone walks the surface to refine the location to within centimetres. This is the surface-pinpointing step that takes correlation results from "about here" to a single saw-cut spot on pavement or a single shovel cut on soil. We carry both fluid-coupled and electronic ground microphones suited to different surface types — asphalt, concrete, grass, gravel — and we operate them as part of an integrated survey, not as a standalone trick.

Why Acoustic Water Leak for ground microphone surveys

Acoustic Water Leak is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.

We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.

Pairs well with

Clients booking ground microphone surveys often combine it with Acoustic Leak Correlation or Hydrophone Inspections — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.

How to prepare for your visit

1. Document what you're seeing. Photos, dates, sounds, water-bill changes, anything unusual. The more we know in advance, the faster we can locate.
2. Clear access to the suspected area. Move furniture, stored items, and rugs. Non-invasive methods still need clear sightlines.
3. Have system history ready. Recent plumbing work, prior leaks, renovations, age of property, prior insurance claims.
4. Confirm the email for your report. Photo-linked report delivered within 48 hours (often same-day for residential).
