At GPR Imaging Solutions we collect ground penetrating radar throughout Melbourne, Australia and New Zealand using electromagnetic waves to provide images below the ground. Waves are transmitted from an antenna and reflected back to the receiver when there is a change in the conductivity of the soil. These changes can be caused by a difference in material type, buried objects, voids and variations in density or moisture.
Asphalt, crushed rock and concrete are some of the various soil types we have successfully analysed using ground penetrating radar in Melbourne, Australia and New Zealand. The depth that ground penetrating radar can penetrate depends on the electrical conductivity of the soil (known as the dielectric constant) and the frequency of the antenna. The dielectric constant is a measure of the materials ability to hold and pass a charge. Values range from 1 (air) to 81 (water). The lower the frequency of the antenna, the deeper the pulse can penetrate underground but at a reduced resolution. Alternatively, the higher the frequency of the antenna, the less the radar pulse can penetrate but better resolution is provided.
Our horn antennas operate at different frequencies to provide both depth of penetration and accuracy in resolution.
Rather than relying on your Asset Manager to interpret the ground penetrating radar results, we provide easy to read reports summarising all key findings and anomalies.
The data analysis techniques we use originated from a world leading expert in the US and are not known by other GPR companies. This is why we have been able to achieve a number of exciting Australian and New Zealand firsts and why you should call us before all others to assist with your project!
