Our Process

Investigation

We start by gathering utility records and using detection tools like GPR, EML, and chamber inspections to map known and unknown underground services.

Mark-out

Utilities are marked on-site using paint, pegs, or chalk to indicate asset type, alignment, direction, and depth.

Report

You’ll get a clear, standards-aligned report with all detections, site notes, and ready-to-use files for design, planning, and records.

Our Tools

Reveal uses cutting-edge technology and skilled field technicians to collect the most precise utility data, including depth and dimensions.

Electromagnetic Locator (EML)

EML is effective for locating metallic utilities such as communications and electric cables, as they produce a distinct electromagnetic signal.

Ground-penetrating radar (GPR)

GPR can corroborate EML detections as well as detect changes in material properties, and can detect both metallic and non-metallic utilities. Suitable for urban centres and rural areas.

Paint

Utilities are marked out along the pavement using colour-coded non-toxic paint and chalk to distinguish the utility type, depth and direction of detected utilities.
