📍 GPR Utility Surveying in London & the South – PAS128-Compliant Surveys by Geo-Radar
Looking for reliable GPR utility surveying in London and the South? At Geo-Radar.co.uk, we deliver high-accuracy ground-penetrating radar (GPR) surveys that map underground utilities quickly, safely, and in full compliance with PAS128 standards.
Whether you’re planning construction in central London, civil engineering in Surrey, or redevelopment across the South of England, our expert GPR technicians provide non-invasive underground utility detection to eliminate the guesswork and reduce risk.
🚧 Why Choose Our GPR Utility Surveys?
At Geo-Radar, we specialise in advanced GPR surveying techniques using high-frequency radar and multi-sensor detection equipment. Our surveys are designed to:
- Locate buried pipes, cables, ducts, and services
- Identify voids, foundations, tanks, and historic structures
- Deliver accurate as-built utility mapping
- Ensure safe excavation in line with HSG47 guidelines
Whether you're a contractor, developer, engineer, or heritage consultant, we provide data-rich outputs and 2D/3D mapping that align with your site needs.
📡 What Is Ground-Penetrating Radar (GPR)?
GPR is a non-destructive survey method that transmits radar pulses into the ground to detect changes in subsurface materials. It’s ideal for urban environments like London, where complex underground networks make excavation risky and expensive without accurate utility data.
GPR is particularly effective in:
- Locating non-metallic services (e.g. plastic water pipes, clay drainage)
- Detecting unknown or undocumented utilities
- Mapping multi-depth utility layers in congested areas
📍 Local Expertise Across London & the South
Geo-Radar is based in the South East and operates across:
- London (Zones 1–6)
- Surrey
- Berkshire
- Hampshire
- Kent
- Sussex
We understand the unique challenges of dense city sites, heritage buildings, and urban redevelopment zones. Our team has conducted GPR surveys near rail networks, under listed buildings, and in high-traffic pedestrian zones — always safely, discreetly, and accurately.
📋 PAS128 Utility Surveying – Accuracy You Can Trust
All our surveys conform to PAS128:2022, the British Standard for underground utility detection. We offer:

🧰 Recent Project Spotlight: Historic Survey in Central London
Our team recently completed a GPR utility and void mapping survey on a 17th-century London site. We uncovered hidden vaults, undocumented pipes, and cellars, helping the developer preserve heritage features while excavating safely.
