What is a GPR Survey?What is a GPR Survey?

Basically, what is a gpr survey scans the ground to find man-made objects and natural elements below the surface. It detects pockets of air, voids, underground pipelines, rock layers, soil profiles, groundwater levels, geological features and more.

The equipment sends out radar pulses that reflect off the object or formation and return back to the sensor. A computer then uses this information to create a graphic representation of the subsurface. This image can then be used to identify the type and location of the item being surveyed. GPR is commonly used for utility mapping (water, sewer & electricity lines), construction surveys and even archaeological research.

It’s a non-destructive technique – meaning it doesn’t cause any harm to the surrounding environment or object. Plus, it can often be used without digging. This saves time and money as well as reduces the risk of accidentally damaging an expensive piece of infrastructure or causing costly delays due to misidentification.

The Science Behind Ground Penetrating Radar Surveys

Another great benefit of a GPR survey is the ability to detect both conductive and non-conductive materials. This is especially helpful if you’re trying to avoid pipes or other objects when working on a project. It’s also fairly accurate, particularly when used in conjunction with a topographical survey.

GPR is very versatile and can be used in a variety of applications, including finding underground utilities, mapping out archaeology or grave sites as well as detecting structures or anomalies within the soil. Except a few conditions, like extremely heavy clays or moisture-saturated soil, it can be used in most environments. GPR is easy to use as well, with most US Radar all-in-one solutions requiring only minor training to operate.
