If you wish to examine what hides beneath that problematic patch of ground with incredible proximity or are just itching to rapidly uncover several hidden secrets, there is no superior means on the market than ground penetrating radar services. The technology permits you to examine the underground layers straight behind the walls of soil-concrete- asphalt material or at present concrete with just about zero means of messy excavation work involved at all. GPR technology has its own roots in the early 1950s and it has significantly changed the whole subsurface investigations’ world by presenting a non-destructive, time-efficient, novel approach to disclose buried objects, prey to utilities, hunting for voids and geological grounding surfaces with minor to nil excavation necessary.
1. Understand the Basics of Ground Penetrating Radar
So, let’s set a formal tone before they get to the business or, actually, to radargram interpretation. “Ground penetrating radar”, often shortened as GPR, “is an artificial device that uses high-frequency electromagnetic radiation for the detection of objects or changes in subsurface properties”. In other words, it is an X-ray for the soil. A GPR system transfers radio waves to the ground where they go until an object or anything denser than the surroundings is discovered. Afterward, the waves come back and are, for instance, reflected. Such waves or their reflections are issued, received, processed, and interpreted by the GPR equipment to understand if that is a length of something utility, a car, a tree, a stone – whatever – how deep is that object. So, GPR is similar to Marco Polo but without answering, using radio waves instead of words.
2. Know Your Site Conditions
But the depth and quality of GPR readings may vary between different sites. Indeed, soil type, its wetness, the presence of different materials, and more may have an impact. If, for example, the soil is clayey and saturated with saltwater, the radar waves will not go deep enough and the survey will be of no use. For that reason, you should be well aware of the site and share whatever information on soil type, wetness, your knowledge of obstructions or utilities underground, and others. This way, GPR professionals will develop their best strategy and adequately control your expectations.
3. Define Your Project Objectives
All GPR service providers are not equal. Thoroughly research and find a reputed company with experienced and certified technicians, knowledgeable about the current GPR technology and techniques. They should have a proven track record of previous successful projects. Ask them about their experience, equipment, and data processing capabilities. Such information will give you confidence in the service provider. A reliable GPR service provider will give you a rational explanation of its methodology and refer to sources or share case studies to confirm their experience.
4. Choose the Right GPR Service Provider
Note that not all GPR service providers are the same. For this reason, you should seek a reputable company with properly trained and certified technicians who are familiar with the current GPR technology and practices. Moreover, the company must have a proven track record of similar projects. Do not shy from asking them about their experience, equipment, and their ability to process data. If the GPR service provider tells you a feasible methodology rationale and provides a source reference or a case study, it is reliable.
5. Prepare the Site for Optimal Results
In order to have accurate and reliable GPR data, proper site preparation is important. In certain cases, this may include removing surface obstructions, which are any vegetation, debris, or loose material that could cause impediments to the radar signals. In addition, the GPR technicians may need to establish a grid system or mark the locations of specific interest to guide them during the systematic process of collecting data; consequently, follow their lead and provide necessary sources.
6. Understand the Limitations of GPR
GPR is indeed an extremely powerful tool, but there are guiding limitations that need to be accounted for beforehand. These include how deep the target is, whether there are any materials such as clay or saltwater to influence the signal, or whether there are any other nearby structures or utilities to interfere with the readings. A good GPR provider is the one who would admit unto such limitations and set realistic expectations. They would also offer to conduct core sampling and use other geophysical techniques.
7. Ensure Proper Data Interpretation
A GPR survey is successful not just on the basis of collecting the data but how well the data is interpreted. GPR data can be complex and it takes an experienced professional to construct the findings. Ensure that the GPR service you hire has experienced analysts who can translate raw data to valuable information and provide clear and detailed reports. You may also need a consultation after the survey to interpret the findings and address arising questions and concerns.
8. Consider Safety and Regulatory Compliance
When surveying using GPR, there is a need to ensure all safety measures are put in place. The precaution will depend on the location of the surveying project and its nature. There might be some safety guidelines recommended or stipulated to be followed on the project site. On other occasions, there may be some permits or approvals needed to conduct a survey using GPR. This could be informed by the fact that the site might be a high-risk zone or some active utilities pass under it.
9. Plan for Potential Follow-up Actions
Do not be surprised if the GPR survey produces results that demand further examination or action. If the image shows underground utilities or buried items that need to be defined and marked, there may be more work to be done. Be ready to talk about how follow-up activities will be conducted with your GPR service provider and plan ahead. This can mean complicated scheduling among utility companies, excavation professionals, and other relevant individuals to make sure that appropriate procedures are applied to all subsurface characteristics identified.
10. Consider the Long-term Benefits
Even though it may seem that the GPR surveys are a one-time investment, the acquired data and insights can bring benefits for a longer period of time. Therefore, the detailed records of GPR surveys’ results, such as reports, maps, and any additional supporting documents, should be kept for future use. Taking into account the potential recurrent needs for the information obtained, it may be used further. Thus, results from a common area or those used for similar purposes may be easily analyzed and compared.
Conclusion
The world beneath their feet is hidden, but ground penetrating radar services from a reliable ground penetrating agency in Dubai provide a fantastic way of seeing into it. Remember that learning the basics, being proficient in site information, selecting the best provider, understanding your limitation, making sure your data are interpreted correctly, following the best health and safety standards and regulations, accounting for possible further actions, and realizing the long-term benefits are all parts of an efficient GPR survey.
