GPR/RFL UNDERGROUND DETECTION
Underground detection using Ground Penetrating Radar (GPR) & Radio Frequency Location (RFL) along with Total Positioning Station (TPS), Global Positioning System (GPS) and Ordnance Survey (OS) data will give you the ability to utilise existing underground services within your project. Underground surveys can also reduce the risk of damage by construction workers due to the unknown location of buried pipes. With minimal disruption our on-site surveyor can get you fast, reliable survey findings from almost any project setting.
Surveying with the very latest technology we have the ability to trace underground utilities in real-time, showing lines of manhole runs, electric, gas, cable TV and water pipes, all with depth, size, type, configuration as well as precise location within your project area.
RADIO FREQUENCY LOCATION
How does RFL work? Metal structures are conductors and generate a magnetic field as the current flows through them. This field can be used for underground detection; by sweeping the RFL receiver over the project area, a detailed digitised image is formed. This equipment can also emit a signal to locate metallic structures such as drainage routes and cables.
The survey will provide you with a comprehensive digital representation of all the underground utilities that is clear, concise and highly accurate.
Services can be marked out on site and accurately plotted onto drawings giving clients the confidence to proceed with a project without any hidden horrors.
Our experienced and highly skilled surveyors use the state-of-the-art equipment with multi directional scanning to trace underground services, ensuring the best results possible.
GROUND PENETRATING RADAR
How does GPR work? A signal is generated by a transmitter and directed downwards through the substrate. As the signal reflects off of subterranean structures and features such as pipes and cables, the difference in reflection is detected by a receiver and recorded as a digitised image. This non-invasive technique is excellent for detecting underground utilities, rebar, voids, pavement/wall thickness, tanks, clay and plastic pipes; both shallow and deep. The advantage being that these are visualised on site giving real-time findings.
