Locate cables and pipes in concrete using Concrete Scanning
Ground Penetrating Radar (X-Ray)
Ground penetrating radar (GPR – Structure Scan) can assist with the location of underground services in many instances where standard radio-detection methods cannot.
GPR technology can assist in the location and depth of:
- water mains – all types, including asbestos, blue brut
- pipes – plastic, poly, pvc
- fire main valves
- fibre optic cables
- road crossings
- rising mains
- buried manhole covers
- underground tanks and pits
Ground penetrating radar is a non-destrutive geo-physical method which uses radar pulses to ‘map’ an image of shallow subsurface features (down to 6 metres approximately). The data collected from the radar sweeping across the surface is collected to construct a view of the subsurface.
Unfortunately, some conditions have a negative impact on GPR performance. High-conductivity (e.g. high moisture content) materials and hetergeneous conditions (e.g. rocky soils) will reduce its performance. For example, whilst dry sandy soils will allow radar penetration to 6 metres approximately, wet clay soils and salt-contaminated soils can reduce the depth to less than one metre. Rocky soils can cause radar signal scattering.
