Geophysical Surveying and Ground Penetrating Radar
Total Scan Survey prides its self on our geophysics department providing high quality professional services for all aspects of geo-technical investigations, including ground penetrating radar in Perth, Sydney, Brisbane, Melbourne and their surrounding areas. Our team are regularly called on for engineering, development and exploration projects across Australia.
With our fully trainedteam of Geo-technical surveyors, GPR experts and CAD operators we perform a high standard Survey or Cable location and offer an output using a number of mapping applications.
Our operatives can accurately map buried anomaly information to create a very effective subsurface mapping solution.
Producing subsurface information for a variety of clients, our output is to an extremely high standard and OHS sound.
Setting out roads, pipelines, car parks, we are experienced in providing complex survey engineering services and solutions.
Additional surveying services can also be undertaken as listed below…
With our proven track record on many large-scale projects Australia wide, we can provide extensive analysis for exploration and engineering purposes of many environmental and geological aspects such as;
Total Scan & Survey provides professional services for geophysical surveying and ground-penetrating radars. This is to make sure that very effective subsurface mapping solution is provided.
Ground-Penetrating Radar is a geophysical method that uses radar pulses to image the subsurface. This non-destructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can be used in a variety of media, including rock, soil, ice, fresh water, pavements and structures. It can detect objects, changes in material, and voids and cracks.
GPR uses high-frequency (usually polarized) radio waves and transmits into the ground. When the wave hits a buried object or a boundary with different dielectric constants, the receiving antenna records variations 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 impedance.
At Total Scan & Survey, we offer the most efficient service in ground penetrating radar in Perth, Sydney, Brisbane and Melbourne and the surrounding areas
Electromagnetic (EM) conductivity instruments have a response that is comparable to that of resistance meters (conductivity is the inverse of resistance). Underground archaeological features are detected by creating a magnetic field underground by applying an electric current that has a known frequency and magnitude through a sending coil. The currents spur a secondary current in underground conductors that is picked up by a receiving coil. Changes in the underground conductivity can indicate buried features. Although EM conductivity instruments are generally less sensitive than resistance meters to the same phenomena, they do have a number of unique properties. One advantage is that they do not require direct contact with the ground, and can be used in conditions unfavourable to resistance meters. Another advantage is relatively greater speed than resistance instruments.
