Why Use GPR for Utility Locating

In the business of underground utility locating services, it is critical that you know what exactly lies beneath the surface at a site such as pipes and conduits. The replacement and rerouting of underground infrastructure can be time-consuming, often very costly and is a disturbance to the environment. It is thus important to utilize tools that would provide accurate assessments and efficiently save on time, resources, and space.

The tools used for locating utilities are quite diverse, but most are met with multiple limitations. One method commonly used is the energizing of cables and metals with electric current and then with the help of a magnetic-field sensor, detect the current. However, there are instances where the metallic object is broken, or there is a presence of non-metallic elements, which makes detection of current impossible or difficult.

Ground Penetrating Radar (GPR) is an underground utility locator that uses radio waves to locate sub-surface structures and objects without causing any damages. The radio waves/signals/frequencies will bounce off the object it comes to contact with and is received back at the antenna. From the antenna, they are transmitted by wire to a computer for processing, analysis, and display on the computer screen.

GPR is used in materials like concrete, asphalt, soil and rock, water, plastic, metal and wood. It can also detect non-objects such as voids (hollow cavities). As such, under favorable conditions, GPR can virtually see anything.

If you are seeking for underground utility locating services, there are multiple reasons why GPR is a good fit. The end goal is to save as much time, resources, and space while getting accurate assessments.

Benefits of GPR

Provides accurate location and detection.

GPR is one underground utility locator that can trace both metallic and non-metallic utilities. These elements may include water, gas pipes, polythene, and even fiber-optic cables, which other methods find difficult or impossible to detect. It can also provide detection of pipe leakages and voids although, this will require further processing of the data.

The underground utility locator will also give you exact locations of these objects inclusive of their depths. More so, it will perform this function without having prior knowledge of the utility’s respective location. It becomes a significant advantage when dealing with an area with complete unknowns.

Provides non-destructive examination.

The GPR underground utility locator uses either magnetic or electromagnetic principles to identify and map out the location of underground utilities. Its approach enables it to reinforce steel within concrete and voids without damaging surrounding surfaces and structures. It also enables non-intrusive inspection of a site, therefore preserving the structure and preventing project downtime.

It is cost effective.

Utilizing GPR underground utility locating services before performing directional drilling will save you from causing damage to existing utilities, which promotes cost-effective installations. It will minimize or eliminate; setbacks from structure damages, expensive job downtime, worker injury, or shutdown of a facility for a severed utility line.

It is user-friendly.

Originally, GPR was considered a major capital investment, dedicated only to experts and skilled operators. The underground utility locator required expertise to operate owing to its complexity and its need for hands-on data processing. However, with technological advancements and innovation, the new GPR equipment is of uncomplicated electronic designs with user-friendly interfaces that do not require complex filter-settings.

Other benefits to using GPR for underground utility locating services include:

  • Early tracing of warning signs and,
  • Fast, reliable diagnosis of problems.

Public vs Private Utility Locating: What’s The Difference?

Are you planning to excavate or dig on your property? First and foremost, you need to locate where utility lines are. This is crucial to avoid consequential damage to mains lines or even injuring yourself in the process. You will need to hire professionals to do the locating job for you to guarantee accuracy. With many lines that could be buried just outside of your property, a proper assessment is absolutely necessary before you go on with your project. If you want to determine the exact location and path of public utility lines, the professional knowledge of a public utility locator will come in handy.

On private property, a private utility locator will be the best fit to do the job. In general, the difference between public and private utility locating services is that public locating has to do with locating utilities in the public right of way while private locating has to do with locating utilities in private property.

Upon locating, you can dig with confidence knowing that you are not at risk of running into a utility line.

Why it is important to call a private utility locate

Since not all utility lines are covered by an 811 Call Before You Dig service, a private utility locator company can help you with locating, marking and mapping of the utility lines.  Especially those owned by a private owner. By using the latest state-of-the-art technology, our technicians will guarantee you a 97% accuracy rate.

Our experience and expertise at locating these type of pipes becomes a great asset for you and serves a great role in damage prevention.

Whether you are planning to build a fence, carry out renovation or undertake a construction project, it is extremely important that you are aware of underground gas lines, sewer lines, fiber optics and water lines that may be passing beneath your construction site. For private utilities, it is a completely different approach compared to public utility. This is because private systems records are not comprehensive and may be missing in some cases. Alternatively, the available records may show a different mapping from the actual installation on the ground. This poses a special challenge that can only be addressed by a professional private utility locator. By using electromagnetic equipment utilities can be accurately located regardless of the material used for the lines.

What you need to do

To be on the safe side of things, you need both private and a public utility locate services. A public utility service is free and can be accessed by calling 811. A public locator will mark any lines that pass near your property such as telephone lines, street lights, traffic lights, cable television lines and any other. However, they are not in a position to mark private lines such as septic systems or buried tanks.
