Ground Penetrating Radar (GPR) is a non-destructive and rapid geophysical method that operates by transmitting electromagnetic waves from an antenna and reflects off layers and objects hidden in the ground. These reflections are collected as data which generates an image of the subsurface. A typical GPR system configuration consists of one or more antenna elements, a control unit and a monitor for storage and display the data.

Ground Penetrating Radar
Why do I need GPR?
Our GPR solution is used to determined the location and depth of underground utilities, especially the non-metallic utilities such as:
– Asbestos Concrete (AC) Water Pipes
– HDPE/PE Pipes
– Fiber optic ducting
– Micro trenching
– Concrete pipes (drainage, sewers)
Other application for the GPR equipment are:
– Scanning for concrete foundation
– Scanning for buried manhole cover
– Scanning for buried septic tank
Considerations
It is useful to understand the limitation of a GPR equipment. For GPR, the ground conductivity is very crucial. If the conductivity is high (for example high water table), the electromagnetic waves are softened, energy loss and no information will be gathered from the depth.
The conductivity can be an issue as follow:
– High density of clay area
– Silty soil
– Salty water
In general, GPR is most efficient if the resistivity is above 100 Ohm-m. Less efficient if resistivity is lower than 50 Ohm-m.
