What is Ground Penetrating Radar And Why Is It Beneficial To Use It?
Ground-penetrating radar is a necessity for many construction projects.

Ground-penetrating radar (GPR) is a method used to detect subsurface obstructions. Radio waves are sent underground with as little invasion as possible, and these waves allow workers to create images that show them where these obstructions are located. By using ground penetrating radar, workers can pinpoint precisely where underground utilities are found in a manner that doesn’t disturb the ground. Ground-penetrating radar is a necessity for many construction projects.

What is the Function of Ground Penetrating Radar?

GPR uses waves with frequencies that range from 1 to 1000 MHz. This process requires a transmitter, as well as a receiving antenna. The transmitter is used to send electromagnetic waves underground. These waves travel through soil and other materials. GPR emits pulses underground, which reach subsurface objects. When the pulses reach any obstructions, echoes are emitted that can be recorded. With the help of GPR imaging tools, you can even find variance in the ground material’s composition.

Any time an electromagnetic impulse makes contact with an object, the object’s density gets reflected and refracted, and the signal gets scattered. The receiver then detects all of the returning signals and records the differences between them. There is software that will convert these signals into images showing the objects that are hidden beneath the surface. By doing this, underground maps can be formed, which help workers determine where it is safe to dig.

What Can Ground Penetrating Radar Find?

GPR is used to detect a variety of items. It’s most efficient whenever there is a great disparity between the object’s electromagnetic properties and the material that surrounds the object. Most often, the items that are found include metal, concrete, PVC, plastic, and natural materials.

Utility Mapping Applications

Subsurface utility mapping uses GPR technology to be more precise with their work. GPR is useful for finding any unmarked structures and utilities, as well as excavating projects. It’s a non-invasive and cost-effective solution for gathering vital intel on what can be found underground. With the help of GPR, everyone on a worksite is kept safer, and a job can be completed more quickly and efficiently without doing any unnecessary digging.
