What is Ground Penetrating Radar?

Ground penetrating radar is a geophysical method of locating that uses radar pulses to image what is under the ground. GPR is a non-destructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies).

How does GPR work?

GPR detects the reflected signals from subsurface structures and has a wide range of applications including locating rock, soil, ice, water, pavements and underground structures. It’s also used to detect changes in material, and voids and cracks.

Deeper technical information about Ground Penetrating Radar.

The depth range of GPR is limited by the electrical conductivity of the ground, the transmitted center frequency and the radiated power. As conductivity increases, the penetration depth also decreases. This is because the electromagnetic energy is more quickly dissipated into heat, causing a loss in signal strength at depth.

  • Locate underground services Higher frequencies do not penetrate as far as lower frequencies, however they will give better resolution image.
  • Dial before you dig up your property to locate underground servicesThe best depth penetration occurs ice. GPR can achieve the depth of penetration of up to several hundred meters.
  • Find the depth of underground services on your property Good penetration is also achieved in dry sandy soils or massive dry materials such as granite, limestone and concrete where the depth of penetration of up to 15 meters can be achieved
  • Find the depth of underground services on your property In damp, high moisture or clay-laden soils and soils with high electrical conductivity, penetration is sometimes only a few centimetres

GPR uses transmitting and receiving antennas or some GPR units can also have one antenna containing both functions. The transmitting antenna radiates short pulses of the high-frequency (usually polarized) radio waves into the ground. When the wave hits a buried object or a boundary with different constants, the receiving antenna records changes in the reflected return signal. The principles involved are similar to reflection seismology, except that electromagnetic energy is used instead of acoustic energy, and reflections appear at boundaries with different dielectric constants instead of acoustic impedances.

The differences between service locating and ground penetrating radar.

Both service locating and ground penetrating radar are effective, but each has its benefits. Service locating enables us to locate services with an electromagnetic field. In some cases a service may be non-metallic. With ground penetrating radar, a wider range of materials can be detected. Additional applications include -

  • Ground Pentrating Radar Service LocatingUnderground utility services including gas, power, water, optic fibre, communications, storm water, sewerage and manholes
  • Ground Pentrating Radar Service LocatingSewer lines and manholes
  • Ground Pentrating Radar Service LocatingStormwater lines and manholes
  • Ground Pentrating Radar Service LocatingDiscovery of services not shown on council or utility plans
  • Ground Pentrating Radar Service LocatingFibre-cement

We're fast at locating services

Qld Utility Locating can locate the following services:

    • Services locator OptusOptus
    • Services locator NBNNBN
    • Services locator ElectricalElectrical
    • Services locator gas linesGas metallic & non-metallic pipes
    • Services locator for fire mains Water and fire service mains, metallic and non-metallic
    • Services locator for drains and stormwater pipesDrains
    • Services locator sewer drainsSewer drains

    Be aware that some service locating operators can only locate metallic pipe work, but we're able to also locate plastic pipes. It is essential to locate underground services before you start any project. Beware that you may cause damage and encounter unexpected expenses to repair any damage if you damage a public utility. Also be aware that striking electrical cables can not only be costly but highly dangerous, causing injury or death.

Safety for teams. Better project outcomes.

Top project management and the inclusion of a site survey with ground penetrating radar avoids damage to any service utility like water, power, gas or stormwater. It also avoids the risk or the unplanned disruption to a project that can cause us thousands of dollars in projects being delayed, with or unforeseen repairs. Most importantly, it will ensure that the risk to personal injury or even death is removed from a project site.
