GROUND PENETRATING RADAR

Ground Penetrating Radar Brisbane & Gold Coast

GPR SOLUTIONS FOR UTILITY INFRASTRUCTURE IDENTIFICATION

The Ground Penetrating Radar (GPR) is the tool of choice for those who need to identify the presence of buried utility infrastructure quickly and easily, both metallic and non-metallic.

Modern technological advances, particularly in the design and construction of buried utilities, have resulted in an ever-increasing use of non-metallic materials. GPR Locator professionals know the difficulties associated with non-metallic utilities and that conventional locating tools leave you a few pieces short. So let the ‘Easy Locator’ help you fill in the missing details. GPR is the only technology available that does not require a physical connection to the utility, nor does it rely on radiating electromagnetic (EM) fields that may or may not be present or detectable.

Lambert Locations have numerous Ground Penetrating Radar Systems (7 in total) ranging from Single to dual antenna for a vaster approach to this newly evolving technology.

GPR MAIN APPLICATIONS

The ‘Easy Locator’ caused a revolution when it was initially released and quickly established itself as the GPR tool of choice for utility applications, such as:

✔ Utility detection & marking

✔ Underground Storage Tank (UST) detection

✔ Locate service

✔ Lost cover, valve, cable box, or vault detection

And many more! With a fast start-up and minimal set-up, the Ground Penetrating Radar system can be rapidly deployed, and the user can collect real-time data at full walking speed within minutes of arriving at the job site. An optional feature allows images of the screen data to be saved in jpeg format, which can then be exported via a USB thumb drive for use in field reports.

WHAT IS A GROUND PENETRATING RADAR?

Ground Penetrating Radar (GPR) is a technology that uses electromagnetic waves to detect objects in the ground. These radar pulses are used to create an image of the subsurface without any damage or disturbance. Ground Penetrating Radar can be used for structural mapping, water resource detection, pipeline location, and many more applications in various fields. It is a geophysical method that uses high-frequency electromagnetic waves to penetrate the earth and measure the properties of the subsurface from distances up to 15 m or more.

HOW DOES GPR WORK?

To understand the way GPR works, it’s essential to know how radar waves work. Radar waves are created when radio signals are bounced off objects, which makes a particular echo pattern read by the GPR equipment. GPR uses reflected radio waves, or ‘radar’, to see what’s under the surface – this means that for GPR scanning to take place, the equipment must be able to transmit radar waves deep underground. GPR operates at high frequencies of 100 MHz to 5 GHz, and the returning signals provide information about what’s underground and identify anomalies such as possible buried pipes, cables, or structures.

These types of waves are produced by an antenna connected to an oscillator, and their electric field penetrates the ground where they interact with the electrical conductivity of geological materials; different materials have different resistivities and will provide return signals at different frequencies, so a GPR profile is obtained that can be used to determine the composition of other materials.

The subsurface is often divided into two parts: near-surface and deep. Near-surface refers to the ground surface down to a depth of approximately 3 m (10 ft). This may include manmade structures such as roads or sidewalks; in these cases, GPR can estimate their thickness. Deeper than this, there are typically very few reflections from interfaces between soil layers because they are too far away.

WHAT ARE THE BENEFITS OF GROUND PENETRATING RADAR SERVICES?

One of the main advantages of using a Ground Penetrating Radar expert is that the process is minimally invasive, with no drilling, boring, or excavation necessary to see what’s below the ground. GPR equipment can be easily transported and set up onsite, wherever you are in Queensland, meaning that you don’t need to go through the long excavation process. GPR is also incredibly safe and can be used to investigate potential underground hazards without any exposure. The images created by a GPR survey show detailed information about what’s under the ground. As technology improves, we have seen a massive increase in the services we can offer. These detailed images can be used when planning construction work, excavations, or drilling.

GPR can also be used to determine the dimensions of any underground structures, such as pavement thickness, the layer thickness of walls, and how extensive any foundations are. This also means that GPR is used extensively in archaeology, construction, and engineering. It can also be used to find buried objects and is used by law enforcement and forensics teams.
