Ground-penetrating radar (GPR) is a geophysical locating method that uses radio waves to capture images below the surface of the ground in a minimally invasive way. The huge advantage of GPR is that it allows crews to pinpoint the location of underground utilities without disturbing the ground.

How much does ground penetrating radar services cost In South Africa?
Ground-penetrating radar cost usually starts around R 214151.56 USD for a simple, single-frequency GPR system. The most affordable systems include a cart, tablet controller, battery, and basic Acquisition Software. This is everything needed to begin basic utility locating and other applications.
How far can ground penetrating radar go In South Africa?
100 feet
GPR can reach depths of up to 100 feet (30 meters) in low conductivity materials such as dry sand or granite. Moist clays, shale, and other high conductivity materials may attenuate or absorb GPR signals, greatly decreasing the depth of penetration to 3 feet (1 meter) or less
Does ground penetrating radar work In South Africa?
GPR uses energy waves in the microwave band, ranging in frequency from 1 to 1000 MHz. The transmitter sends electromagnetic energy into the soil and other material. Ground Penetrating Radar works by emitting a pulse into the ground and recording the echoes that result from subsurface objects.
What are the disadvantages of using a ground penetrating radar In South Africa?
Among methods used in archaeological geophysics, it is unique both in its ability to detect some small objects at relatively great depths, and in its ability to distinguish the depth of anomaly sources.
The principal disadvantage of GPR is that it is severely limited by less-than-ideal environmental conditions.
