Without Digging

Ground penetrating radar (GPR) uses electromagnetic radiation pulses to image the subsurface. The system emits pulses of energy into the ground which are reflected back when they encounter boundaries between materials with different electrical properties — such as a buried pipe, a void, or a change in soil type.

The reflected signals are recorded and processed to produce a continuous profile of the subsurface, allowing trained operators to identify the position and depth of buried features. GPR is a completely non-destructive method — no excavation, no ground disturbance, no risk to existing services.

The use of GPR is mandatory in the majority of mapping surveys where non-metallic services could be present. Traditional cable avoidance tools (CAT scanners) cannot detect plastic water pipes, clay drainage, fibre optic cables or other non-metallic services. GPR can detect these where CAT cannot.

GeoPrime Solutions carry out GPR surveys across the UK for utility mapping, void detection, concrete investigation and general subsurface investigation. Our operatives are trained and experienced in GPR data acquisition and interpretation.

GPR Can Detect
  • Buried utilities — metallic and non-metallic
  • Plastic water pipes & clay drainage
  • Fibre optic cables
  • Underground storage tanks
  • Voids and cavities
  • Foundations and structures
  • Reinforcement in concrete
  • Changes in ground conditions

The Process

How a GPR Survey Works

01
Site Assessment
We assess the site, agree the survey area and select the appropriate antenna frequency for the required depth and resolution.
02
Data Acquisition
The GPR antenna is passed systematically across the survey area. Electromagnetic pulses are emitted and reflected signals recorded in real time.
03
Data Interpretation
The recorded data is processed and interpreted by our trained operatives to identify the position, depth and nature of buried features.
04
Reporting
Results are presented as a clear site plan showing the location and depth of identified features, together with a written report and supporting data files.
Applications

Where We Use GPR

Utility Mapping
Mapping buried services prior to excavation, including non-metallic services undetectable by traditional CAT scanners.
Void Detection
Identifying voids, cavities and sinkholes beneath roads, pavements and structures before they become a safety hazard.
Concrete Investigation
Locating reinforcement, post-tension cables, conduits and voids within concrete slabs, walls and structures.
Infrastructure
Investigation of highways, bridges and transport infrastructure for buried features and structural anomalies.
Pre-Demolition
Identifying buried tanks, foundations and services on sites prior to demolition or redevelopment.
Environmental
Locating buried tanks and drums on contaminated land sites as part of environmental investigation programmes.

Why Choose Us

Why GeoPrime for GPR Surveys

Mandatory Compliance
GPR is mandatory where non-metallic services may be present. We ensure your survey meets the requirements of PAS 128 and all relevant industry standards.
Experienced Operators
GPR data is only as good as the operator interpreting it. Our team are trained and experienced in both data acquisition and interpretation across a wide range of site conditions.
Clear Reporting
Results are delivered as a clear site plan with identified features marked, together with a written report and supporting data. You get information you can actually use.

Frequently Asked
Questions

GPR is a non-destructive geophysical method that uses electromagnetic radiation pulses to image the subsurface, identifying buried utilities, voids, structures and other anomalies without excavation.
GPR is mandatory in the majority of mapping surveys where non-metallic services could be present. Traditional CAT scanners cannot detect plastic pipes, clay drainage or fibre optic cables — GPR can.
GPR can detect buried utilities (metallic and non-metallic), voids, underground storage tanks, drainage systems, foundations, reinforcement in concrete and other subsurface anomalies.
Penetration depth depends on antenna frequency and ground conditions. Higher frequency antennas give better resolution at shallow depths; lower frequencies penetrate deeper. In ideal conditions, several metres of penetration is achievable.
Yes — GPR is completely non-destructive and non-invasive. It poses no health or safety risk to operatives or the public and requires no excavation or ground disturbance whatsoever.
