Ground Microphone Surveys in Delta

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.

What acoustic leak detection typically finds in Delta

Distribution mains in dyke-protected service zones, common-line leaks in older Ladner stratas.

Delta's built environment — single-family in Ladner and North Delta, low-rise development in Tsawwassen, agricultural and industrial in Tilbury and Ladner farmland — shapes how ground microphone surveys is delivered locally. Most of Delta sits at or below sea level on the Fraser delta, protected by dykes and pump stations. Water-table issues, slab leaks and stormwater inflow into sanitary systems are recurring themes, and utility work has to respect strict drainage and ALR constraints.
