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 concrete, rock, soil, ice, fresh water, pavements and structures.
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 fields as a form of non-destructive testing (NDT) on structures and pavements. It can be used for concrete scanning, corrosion in concrete, concrete thickness, reinforcement cover, reinforcement size and more... A key part of the construction process is allowing companies to safely scan before cutting and coring concrete. The method can safely and accurately identify and map rebar, electrical conduits, water lines, PT cables and more...
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.
