Question 1

What is Ground Penetrating Radar (GPR)?

Accepted Answer

Ground Penetrating Radar (GPR) is a non-destructive geophysical method that uses radar pulses to image the subsurface. It works by transmitting high-frequency radio waves into the ground and recording the reflected signals that bounce back when they encounter different materials or objects. This technology allows us to 'see' beneath surfaces without any excavation or damage.

Question 2

How accurate is GPR technology?

Accepted Answer

GPR technology is highly accurate, capable of detecting objects and features to within centimeters of their actual location. However, the accuracy can be affected by factors such as soil conditions, moisture content, and the depth of the target. Our experienced technicians are trained to interpret GPR data accurately, taking these factors into account.

Question 3

How does GPR detect water leaks?

Accepted Answer

GPR detects water leaks by identifying areas of moisture concentration in the subsurface. When radar waves encounter moisture, they behave differently than when they encounter dry materials, creating distinctive patterns in the GPR data. Our technicians are trained to recognize these patterns and pinpoint the source of leaks.

Question 4

What can GPR detect in concrete?

Accepted Answer

GPR can detect a wide range of objects and features within concrete, including rebar, post-tension cables, conduits, pipes, voids, and even variations in concrete thickness or quality. This makes it an invaluable tool for planning safe cutting, drilling, or modification of concrete structures.

Question 5

What types of utilities can GPR detect?

Accepted Answer

GPR can detect a wide range of underground utilities, including water pipes, sewer lines, gas lines, electrical conduits, communication cables, and more. It's effective for both metallic and non-metallic utilities, making it more versatile than traditional utility locating methods that rely on electromagnetic detection.
