GPR Surveys – Ground Penetrating Radar

Benefits Of GPR Surveys

Ground Penetrating Radar (GPR) Surveys are used in the pre-planning stage of various excavation works, in order to secure the safety of the process. The ground penetrating radar surveys the underground, gathering information about cables and other ductwork that may interfere with your excavation works.

We are experts in land surveying and setting out, our engineering training enabling us to offer you top-notch project management assistance prior to design and construction.

What Can Ground Penetrating Radar (GPR) Surveys Detect?

Plastic pipework, steel reinforcement in concrete, voids, holes, and underground tanks are only a few of the obstacles a Precision GPR survey can detect. If you need to locate various items before you start your ground excavation works, a GPR survey is exactly what you need. Our survey specialist will work together with you to detect all underground utilities, voids, tanks, and obstacles such as trees near foundations, in order for you to gain an accurate view of what’s buried there. Sometimes, maps of local services aren’t updated or they may have to be sourced from multiple providers, hence turning pre-planning into a cumbersome task.

Who Needs Ground Penetrating Radar (GPR) Surveys?

Advice from The Health and Safety Executive recommends three steps to be taken in order to ensure safe excavations. Companies should carefully plan their works with emphasis on their safety. Next, they should do everything needed to detect and locate all underground services underneath the excavation site. Finally, they should employ only safe digging practices in those areas where underground services such as pipes, tanks, and wiring are located.

Benefits of GPR Surveys

Ground Penetrating Radar Survey can detect both metallic and non-metallic obstacles, hence being able to locate polyethylene Gas and Water pipes that are impossible to detect with other methods. This method is also able to detect fiber optic cable, which is very costly to repair, should it get damaged during excavation works.

We are honest and open, always ready to answer all your questions and offer you expert advice in regard to the route to take to obtain the information you need to proceed with your excavations. We won’t claim that GPR will always detect all obstacles, each and every time. In fact, this equipment also has its limitations, just like any other radar equipment on the market. Wet and clay ground conditions will have a negative impact on the GPR penetration range. Knowing this, we always use it in conjunction with our radio detection equipment, for an accurate mapping survey service.

We strongly believe that by using Electromagnetic techniques first can boost the success rates of our projects by eliminating conductive services right off the bat.

Using GPR equipment requires to have an Ofcom license. You can rest assured that Discover Surveys has all relevant licenses required by law to conduct this type of radar surveys legally.
