Ground Penetrating Radar (GPR) technology has revolutionized how we understand what lies beneath the surface. Whether you’re in construction, archaeology, utility detection, or any field that requires subsurface exploration, GPR scanning is often the method of choice for identifying buried objects without disturbing the ground. But, as the need for precise subsurface imaging grows, one question emerges: Should you rent, purchase, or hire a GPR service?
Let’s explore why you need the use of GPR, and which option is the best for your project needs.
Why is GPR the Method of Choice?
GPR is used for a wide range of applications, from locating buried utilities and detecting voids, to archaeological investigations and assessing the structural integrity of buildings. Here are some of the most common reasons why GPR would be the preferred choice for your requirement:
- Safety and Compliance. It is safe for use in public spaces. Avoid accidents by detecting underground hazards, such as electrical cables and gas lines, before excavation.
- Non-Invasive. GPR technology allows you to visualize the subsurface without digging or drilling, preserving the integrity of the site.
- Accuracy and Precision. GPR provides high-resolution data, ensuring accurate mapping of subsurface features. When used by skilled technicians, it’s typical to achieve accuracy rates of over 90% in detecting and mapping buried utilities.
- Speed. GPR data is gathered quickly and can cover a large site area in little time. Data collected during the survey can also be seen immediately, or analyzed more heavily in post-processing. For example, a typical GPR survey covering a 10,000m2 area can be completed in just one day, significantly faster than other methods.
- Cost Efficiency. The method and speed of data collection make GPR the most cost efficient method for a variety of uses. As well as this, its use to identify potential issues early saves money on repairs and delays. GPR can save construction projects up to 20% in costs related to delays and damages..
Given these benefits, it’s clear that GPR scans are invaluable as an extremely cost-effective and non-invasive way of surveying. However, the next step is deciding how to access this technology.
Renting GPR Equipment
Renting GPR equipment can be an appealing choice for those who need the technology on a temporary basis. However, renting GPR equipment has its downsides. The most significant challenge is the learning curve associated with using it. Mistakes can be costly in both time and money, particularly if you’re unfamiliar with GPR technology.
Moreover, without professional expertise to accurately interpret the data, the results may lack the accuracy and insight needed for complex projects, which can be very problematic. For this reason the professional designation RULT was created, providing invaluable support to the ground disturbance community. All RULT applicants must be able to demonstrate a minimum of 2-years relevant work experience as an underground utility locator.
Purchasing GPR Equipment
Purchasing GPR equipment might seem like a good investment, especially if you plan to use it frequently. But the high cost of purchasing GPR equipment—often tens of thousands of dollars—can be prohibitive. A basic GPR unit like those from Impulse Radar, Proceq, GSSI, or Mala can cost anywhere from $15,000 to $100,000, depending on the features and specifications. Additionally, the owner must invest time in learning to operate the equipment effectively, which can lead to costly mistakes and inefficient use of time.
Hiring a GPR Service
This leads us to the most commonly used option in these circumstances. Hiring a GPR service is often the most practical and cost-effective option, especially for those who require expertise and precision. Here’s why hiring a service might be the best choice:
- Expertise: GPR service providers have experienced professionals who understand the nuances of subsurface scanning, ensuring accurate results.
- Efficiency: Experienced operators can complete projects quickly and efficiently (often with multiple technicians and devices), minimizing downtime and costs.
- Comprehensive Analysis: Service providers offer detailed reports and insights that only come with experience and expertise.
While hiring a GPR service may initially appear costlier than renting, the value of expert knowledge and the accuracy of results often justify the expense. You gain access to a team that can provide insights and recommendations that only seasoned professionals can deliver.
