Common Misconceptions about GPR Concrete Scanning and Underground Utility Locating

by admin in Uncategorized

While underground utility locating services and ground penetrating radar is certainly not a new industry, there are still many misconceptions that members of the public still hold. This list will dispel some of the myths and allow you to understand the technology so that you can start your next project with the highest level of confidence. 

  • Myth 1: There are no underground utilities shown in the utility map of my excavation area, so I don’t require any locators: Records of where certain utilities are buried can be dated or inaccurate. For safety’s sake, you should not assume that simply because there are no underground utilities showing that it is safe to just start digging.
  • Myth 2: I can scan myself if I buy the equipment: GPR analysts go through extensive training to be able to interpret the data that the equipment they use gives them. A person who has no training using this equipment and interpreting the data they produce can make a mistake that could greatly damage your project.
  • Myth 3: GPR can be successful under any surface condition: The moisture content contained in the concrete to be scanned plays a large role in the accuracy of the results the locator produces. For example, high moisture levels can make it difficult to get good readings since moisture increases an object’s conductivity. Other surfaces that can be hard to read include marble, granite, etc. 
  • Myth 4: Utilities which are non-metallic cannot be detected: Even though there are some objects that can’t be read using ground penetrating radar, GPR concrete scanning can still locate some non-metallic objects under the right conditions.
  • Myth 5: Once utility mapping is done you don’t need to do it for future projects: Underground utility locating or pipe locating is an on-going process. Pipelines, fiber cables, etc., can shift and change over the course of time due to natural forces.

These 5 myths are just a few of the many misconceptions that linger about GPR and underground utility locating. The fact is, underneath the ground lies buried pipes and cables and if any of these are struck it could lead to severe consequences. To protect you and your project, it is always wisest to call upon professionals who can locate these kinds of objects before any excavation project is started.
