Underground Cable Location

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 scanning 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
• 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 scanning performance. High-conductivity (e.g. high moisture content) materials and heterogeneous 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.
