When constructing a new building, it’s crucial to understand what lies beneath the surface before construction begins. This helps prevent any costly challenges or discoveries later in the timeline. One way to do this is by gpr surveying. This is a non-destructive process that allows you to see what’s underground without having to dig or probe. It can also be used to find buried objects, including metal pipes and buried drums of hazardous waste.

GPR surveying works by sending radar waves into the ground. These waves return to the surface with information about the structure and composition of the subsurface. They show layered geological formations as well as the location of man-made structures. Depending on the frequency of the signal and the size of the target, different data sets are obtained. The most commonly used is a time-reversed “cross-section” display of the target.

Essential Equipment for Conducting GPR Surveys

The gpr equipment uses a transmitter and receiver antenna to measure the time delay of reflection from a target object. The resulting plot of these measurements, called a scalar radar profile, is a hyperbola whose apex is the corresponding location of the target object. This method can be used to locate a variety of underground utilities such as metal or PVC pipe, and electrical and plumbing services.

It can also be used to locate buried debris, such as drums of hazardous waste, for environmental remediation purposes. The data can also be used for archaeological work and forensic investigations.
