Overview

Know What Lies Beneath Before You Dig

AAMS combines ground-penetrating radar (GPR) with AI-driven data interpretation to locate and map underground utilities, pipelines and voids with minimal excavation. Our experienced geophysical specialists use state-of-the-art GPR systems to deliver high-resolution subsurface intelligence with minimal disruption to site activities.

Our subsurface detection surveys support safe excavation, utility coordination and infrastructure asset management across urban, industrial and transport environments. AI-assisted classification and 3D mapping transform raw GPR data into clear, georeferenced utility models, reducing strike risk, avoiding costly delays and accelerating project planning.

What we deliver

Core Capabilities

Ground-based and airborne GPR, interpreted with AI and delivered as clear 3D models, so teams can plan and excavate with confidence.

01 / Detection

Underground Utility Detection & Mapping

GPR sends radar pulses into the ground and records reflections from buried objects, allowing us to locate metallic and non-metallic utilities including pipes, cables, ducts and conduits that traditional cable locators can miss.

Detected services are surveyed and georeferenced, then delivered as utility maps and CAD layers that show location and approximate depth, giving designers and contractors a reliable picture before excavation.

  • Pipes, cables & ducts
  • Depth estimation
  • Utility maps

02 / AI interpretation

AI-Assisted Interpretation & 3D Utility Models

Raw radar data is complex. AI-assisted classification helps our specialists identify utilities, anomalies and subsurface features consistently across large datasets, reducing interpretation time and improving reliability.

Results are combined into 3D, georeferenced subsurface models that integrate with survey, BIM and GIS data, so underground assets can be viewed alongside everything above ground.

03 / Investigation

Void, Cavity & Subsurface Anomaly Detection

GPR detects voids, cavities, sinkholes and changes in subsurface conditions beneath roads, slabs, foundations and runways. Early detection helps prevent collapse, structural damage and costly emergency repairs.

We also use GPR for concrete scanning, locating rebar and embedded services, and assessing the condition of pavements and structures.

Drone-Based Airborne GPR

In addition to ground-based investigations, AAMS offers airborne GPR surveys using drone platforms. Drone GPR enables rapid, non-intrusive investigations over large, linear or hard-to-access areas.

It is particularly effective for corridor surveys, remote locations and sites with limited access, providing efficient data acquisition while maintaining high safety, accuracy and operational standards.

  • Corridor surveys
  • Remote sites
  • Limited-access areas

FAQ

GPR Survey Questions, Answered

Not sure which approach suits your project? Our team can recommend the right method, equipment and deliverables.

What is a GPR survey?

Ground-penetrating radar (GPR) is a non-intrusive geophysical method that sends radar pulses into the ground and records reflections from buried objects and changes in material. It is used to locate utilities, voids and other subsurface features without excavation.

Can GPR detect plastic pipes?

Yes. Unlike electromagnetic cable locators, GPR can detect non-metallic utilities such as plastic and concrete pipes, as well as metallic services. Detection depends on ground conditions, depth and the size of the target.

How deep can GPR detect utilities?

Detection depth depends on soil type, moisture and the antenna frequency used. Dry, sandy ground typically allows deeper penetration than wet clay. We select equipment and survey settings to suit your site and the depths you need to investigate.

How does AI improve GPR interpretation?

AI-assisted classification helps identify utilities and anomalies consistently across large volumes of radar data. Combined with specialist review, it speeds up interpretation and produces clearer, georeferenced 3D utility models.

When is drone-based GPR used?

Drone GPR is used for long corridors, remote locations and sites that are hard or unsafe to access on foot. It covers large areas quickly while keeping crews away from hazards.

Why survey utilities before excavation?

Striking a buried utility can cause injuries, service outages, damage and costly delays. A GPR survey before excavation identifies what is below ground so works can be planned and carried out safely.
