Xradar™ Enhanced Concrete Scanning

Xradar™ is an advanced imaging capability, utilizing GPR (Ground Penetrating Radar) technology. It uses radar amplitude, phase and shape to achieve maximum performance for freehand B-scan analysis.
Xradar™ is a non-destructive process used for scanning the subsurface for hidden objects. The process works by sending high-frequency electromagnetic waves into the ground from a transmitting antenna. These waves are then reflected back up to form an image of the subsurface. It can be used across a wide range of materials, including rock, soil, ice, fresh water, pavements and structures. Ground Penetrating Radar is able to detect subsurface features whose electrical properties contrast with those of the surrounding soil or concrete.

Applications of Ground Penetrating Radar and Xradar™

Xradar™ Enhanced Concrete Scanning has applications in a number of fields. Most commonly it can be used in construction and engineering as a form of non-destructive testing (NDT) on structures and pavements. It can be used for concrete scanning, corrosion mapping, utility locating, and oil tank locating, to name a few.

As part of the construction process, allowing companies to safely scan before cutting and coring concrete. It is also utilized in the mapping of deterioration and corrosion in concrete, necessary in maintaining the safety of concrete structures.

Other applications can be found in archaeology, with the detection and mapping of archaeological features and cemeteries. GPR also has uses in military and law enforcement, for the detection of dangerous objects such as landmines.

Understanding the Technology

The systems used by Xradar™ consist of a transmitter, a receiver, and a control unit. The transmitting antenna begins by sending electromagnetic waves into the ground, which are then reflected off underground layers and objects.

Reflections are produced whenever the wave enters a material that differs in its conductive properties from the material it left. The receiving antenna then receives the wave reflections and measures the travel time and strength. This is then converted into an accurate image of whatever is below the surface.

A number of factors can be altered depending on the requirement of the process and we tailor methods and procedures to client needs. Changing the frequency of the wave can alter the depth and detail of the scan, therefore antenna choice is one of the most important factors in survey design.
