At GPR Utility Surveys in Egham, we provide accurate, non-invasive underground utility mapping using Ground Penetrating Radar technology.

Our services support contractors, engineers, and site managers in Egham and throughout the UK by identifying subsurface services before excavation begins, helping to prevent utility strikes, costly delays, and unexpected risks.

Whether your project involves infrastructure works, site assessments, or design planning, our GPR utility surveys offer clear and reliable data on underground conditions.

How Are GPR Utility Surveys Used on Sites Around Egham?

In Egham, GPR utility surveys are used to identify buried utilities that electromagnetic locators may miss, such as plastic water pipes, fibre-optic ducts, or services beneath reinforced surfaces.

The method transmits high-frequency radar waves into the ground, which reflect back when they encounter changes in material like voids, cables, or pipes. 

GPR utility surveys are particularly beneficial in roads, construction zones, and urban areas where accurate underground detection is crucial.

What Types of Underground Services Can Be Detected Using GPR Across Egham?

A GPR utility survey in Egham can detect a wide variety of buried features, including:

• Plastic and clay water pipes – Non-metallic utilities that are typically invisible to electromagnetic locators.
• Empty ducts and conduits – Detection of unoccupied service routes, such as fibre-optic channels.
• Fibre-optic cables – Non-conductive infrastructure often undetectable by conventional survey tools.
• Drainage runs and stormwater pipes – Mapping subsurface drainage systems and flow paths.
• Voids and air pockets – Identifying potential voids or areas of subsurface instability.
• Underground tanks and chambers – Locating structures like oil tanks, septic units, or valve chambers.
• Metallic cables and pipes – Visible under appropriate soil conditions and radar settings.
• Changes in sub-base materials – Differentiating construction layers under roads or pavements.
• Unknown foundations or footings – Revealing historical or undocumented structures underground.

How Much Do GPR Utility Surveys Cost in the Egham Area?

The cost of GPR utility surveys in Surrey ranges from £600 to £2,000+, depending on site conditions, required accuracy, and survey complexity.

Factors influencing price include ground type, radar frequency selection, the need for CAD integration, post-processing, and whether PAS128-compliant reporting is required.

When Should You Use GPR for Utility Detection Near Egham?

GPR utility surveys are particularly useful in Egham when detecting non-metallic or deep-buried services where electromagnetic tools fall short.

Ideal scenarios include identifying plastic pipes, fibre-optic cables, and services in heavily congested areas or beneath reinforced concrete.

GPR is also suitable for heritage or restricted-access sites where intrusive work is not allowed.

Use GPR when a detailed understanding of below-ground infrastructure is required before design, excavation, or verification.

How Accurate Are GPR Utility Surveys for Projects in or Around Egham?

In Egham, GPR utility surveys typically achieve horizontal accuracy between 100mm and 300mm, influenced by the ground composition and surface type.

Depth accuracy is generally within 10–15% of the target depth under favourable conditions, such as sandy or dry soil.

However, dense clay, moisture saturation, or structural reinforcement may affect radar performance and signal clarity.

What’s the Difference Between a Standard Utility Survey and a GPR-Based Scan?

GPR utility surveys use radar technology to identify a wider array of underground features, including non-metallic pipes, voids, ducts, and structural elements that electromagnetic methods often miss.

Unlike standard utility surveys, which typically rely on electromagnetic detection limited to conductive or metallic services, GPR surveys provide both depth and positional data, offering a detailed subsurface profile.

This makes GPR particularly valuable in complex, congested, or poorly documented environments where a complete understanding of underground conditions is essential.

Can GPR Utility Surveys Be Performed on Live Construction Sites Within Egham?

GPR utility surveys can be safely carried out on active construction sites in Egham. The method is non-destructive and compatible with ongoing site activity.

Our team is trained to work alongside other operations, using approved PPE, risk assessments, and health and safety protocols. Surveys can be scheduled to avoid operational interference and are often completed within limited time windows without halting progress.

What Equipment Is Used for GPR Utility Mapping Conducted Near Egham?

Our GPR utility surveys in Egham are conducted using professional-grade tools suited to the project requirements:

• Single-frequency and dual-frequency antennas – Used to balance detail and depth based on target features.
• Wheeled or cart-based GPR units – Allow efficient coverage over large or complex terrain.
• IDS Stream C and Leica DS2000 – Industry-recognised radar systems for high-resolution and depth-specific scans.
• GPS and total station control – Ensures accurate geo-referencing of survey results within site boundaries.
• Specialist post-processing software – Converts raw data into clean, interpretable underground maps.
• Custom equipment configurations – Adapted to suit different surfaces, depths, and expected utility types.

Are GPR Utility Surveys in Egham PAS128-Compliant and Suitable for Legal Documentation?

GPR utility surveys in Egham can be performed in compliance with PAS128 standards, typically as part of a Type B survey. GPR methods are categorised under Method M3 or M4, depending on whether they are used independently or with complementary techniques.

Our surveyors follow PAS128 protocols, classify findings according to quality levels, and generate deliverables—including CAD files and structured reports—suitable for risk analysis, planning applications, and legal documentation.
