GPR Survey Services from CSW Survey Ltd

Enhance your project with expert GPR Survey Services from CSW Survey Ltd. GPR provides detailed images of subsurface structures, allowing for the precise location of utilities that traditional methods may miss. Our expertise ensures rapid data collection with minimal disruption to your project schedule.

Ground Penetrating Radar (GPR) is a cutting-edge technology used to detect and map underground utilities and anomalies hidden below ground. GPR is an advanced geophysical method that uses radar pulses to create detailed images of subsurface structures. At CSW Survey Ltd, we specialise in offering expert GPR survey services to ensure the success and safety of your construction and excavation projects.

Benefits of Our GPR Surveys

Comprehensive Detection of Non-Metallic Utilities

Our state-of-the-art GPR technology identifies non-metallic utilities such as plastic pipes, fibre optics, and drainage systems. By pinpointing these assets, we help you get a comprehensive picture of underground services and avoid damaging infrastructure, reducing the risk of costly delays and hazards.

Fast and Accurate Data Collection

Our efficient survey process ensures rapid data collection with minimal disruption to your project schedule. We provide precise information on pipe trajectories, ground disturbances, and changes in subsurface conditions, empowering you with the knowledge needed for confident decision-making.

Expert Interpretation and Detailed Mapping

Rely on our experienced surveyors to expertly analyse GPR data and deliver actionable insights. We offer detailed utility maps that integrate seamlessly with your project plans, including essential details such as pipe sizes, directional flow, and materials.

Adherence to Industry Standards

As a leader in underground utility surveying, we adhere to the highest industry standards, including the BSI’s PAS 128 specifications. Our dedication to professional excellence ensures that our surveys are reliable and meet the specific needs of your project.

Case Study: Supporting future district heating installation in Bristol with non-intrusive GPR surveying

As part of an ongoing district heating project around Bristol, our client required a PAS128 Utility Survey and topographical survey to be conducted on the roads and footpaths within our survey boundary. The survey data will be used by a design team, to establish the route for the new district heating infrastructure.

Frequently asked questions

What is Ground-Penetrating Radar?

Ground-Penetrating Radar (GPR) is a non-destructive geophysical method that uses electromagnetic radar waves to create images of the subsurface. By transmitting radar pulses into the ground and capturing the reflected signals, GPR can detect and map the location of underground utilities, voids, and other anomalies. This technology is invaluable for accurately identifying what lies beneath the surface, ensuring safer and more efficient excavation and construction projects.

Can GPR Go Through Concrete?

Yes, GPR can effectively penetrate concrete, making it an ideal tool for detecting embedded utilities, rebar, and structural elements within concrete slabs and walls. The radar waves can pass through concrete and reflect off different materials, allowing for detailed imaging of what lies within and beneath the concrete. However, the depth and clarity of detection can vary depending on the thickness and composition of the concrete.

What Can GPR Detect?

GPR is capable of detecting a wide range of subsurface features, including:

  • Non-Metallic and Metallic Utilities: Plastic pipes, fibre optics, cables, and metal conduits.
  • Structural Elements: Rebar and post-tension cables within concrete.
  • Subsurface Anomalies: Voids, cracks, and changes in material composition.
  • Geological Features: Soil layers, rock formations, and groundwater levels.

The ability to detect these features makes GPR an essential tool for comprehensive utility mapping and site assessment.

What is PAS 128?

PAS 128 is a specification developed by the British Standards Institution (BSI) that provides guidelines for the detection, verification, and location of underground utilities. It establishes a standardised approach to utility surveys, ensuring consistency and reliability in the quality and resolution of detection across different sites. The specification defines four types of surveys, each with varying levels of accuracy and detail, allowing for tailored solutions that meet the specific needs of different stages in a project’s lifecycle. Compliance with PAS 128 ensures that surveys are conducted to the highest industry standards, providing clients with confidence in the accuracy and reliability of the data.
