GPR survey is fully NDT, cost efficient way to identify sub-surface objects and features.
Ground Penetrating Radar survey (also called GPR survey, GPR imaging, GPR mapping or GPR scanning) is used to scan and map underground obstructions
and objects for construction, geophysical, archaeological and regeneration
projects.
GPR survey identifies underground objects by sending non-intrusive radar signals into the ground. Once the signal is received back an image or a map of the entire subsurface area is produced. GPR imaging is a stand alone service which can be coupled with other techniques for increasing accuracy of the results. Since Ground Penetrating Radar (GPR) can detect metallic as well as non-metallic objects, pipes etc. therefor it is frequently used with electromagnetic location (EML) technique which can only detect metallic buried services.
Being fully NDT method, GPR survey increases the safety of your site whilst also reducing the costs associated with your project. GPR survey is efficient and reliable mean of scoping your grounds.

FAQ
Will GPR scanning equipment compromise safety on my site?
GPR survey equipment emits an electromagnetic pulse into the ground and records the reflected signals from subsurface structures and voids. It is entirely non-destructive and will not break the ground’s surface or affect any objects below. What’s more, it doesn’t emit any harmful levels of radiation, nor are there any other by-products created throughout the process. This means it’s entirely safe to use by its operators, and on sites of any type, including those open to the public.
Is GPR survey equipment difficult to use?
The equipment itself is not difficult to use, but the interpretation of the data recorded tends to be complicated. The results of a GPR survey aren’t automatically translated into an easy-to-understand picture of what lies below the surface; instead, it’s a series of lines and waves and it can take both training and years of practice to master the art of correctly reading the output. Often, it is the experience of the equipment’s operator that plays the most significant role in the accuracy of the results GPR can achieve.
Is a GPR survey 100% accurate?
While GPR is one of the most effective methods of non-destructive testing available, it can never be 100% accurate. One factor that can adversely affect the accuracy levels include the type of soil being surveyed. Clay soils and soils that contain high levels of salt or minerals can obstruct the GPR reading. Another factor is the experience of the equipment’s operator: interpreting the data collected can be complex, which is why it’s beneficial to commission surveys from an expert firm.
