The Importance of Ground Penetrating Radar (GPR), Explained

Did you know that GPR scanning (Ground-penetrating radar) can penetrate 100 feet (30 meters) of dry sand or rock? However, the penetration depth can be reduced to 3 feet (1 meter) or less in moist clays and shale.

GPR technology is used in various industries to see artificial and natural materials. For example, using GPR scanning, you can locate metallic and non-metallic pipelines, electrical lines, conduits, water lines, rebar, and post-tension cables inside concrete structures. This service is frequently performed before building or renovations.

Ground-penetrating radar is a non-invasive method of capturing images below ground. Please continue reading to learn about the significance of GPR scanning and its benefits.

The Importance of GPR Scanning

With technology advancing every day, it’s easy to get lost in today’s crowded market. Using GPR scanning over other methods has many advantages, including:

  • GPR gives you instant results
  • GPR scanning gauges the depths of objects being scanned
  • One advantage of GPR is that it can detect nonmetallic objects. This is because it works not only on conductivity shifting media but also on dielectric shifting media
  • The other distinguishing feature of this system is that its three-dimensional data can provide extensive information about its targets
  • In comparison to X-ray, GPR does not pose a radiation risk, has a greater penetrating depth, and can work more efficiently
  • It gives you accurate data

GPR has a wide range of applications, including:

  • Detection of underground storage tanks
  • Identifying underground utility locations
  • Finding air pockets or voids beneath the ground
  • Mapping of cemetery burial plots
  • Identifying the location of rebar
  • Identifying and mapping conduits/pipes in concrete
  • Identifying the location of post-tension cable
  • Groundwater level mapping
  • Mapping of bedrock topography

These are only some of the applications. It shows the importance of ground-penetrating radar in all aspects of the industry.

Things to Remember When Using GPR Scanning

If you are going to require a GPR survey, keep the following considerations in mind:

  • GPRs used in cities are often cart-mounted or on wheels and need a flat, level surface free of impediments
  • Water pools on the ground may prevent GPR from receiving good signals
  • In clay types of soils, the penetrating depth of GPR is limited

GPR scanning services are often used by the following:

  • Airport services,
  • The auto industry
  • GPR for construction of commercial sites
  • Government departments
  • Manufacturing industries
  • The military
  • Municipality services
  • Boat ports
  • Power plants
  • Different refinery services
  • Treatment water
  • The mining sector
  • Ground drilling services

The list goes on and on. But, again, this shows the importance of GPR.
