Concrete X-Ray VS Xradar

January 12, 2018
When searching for concrete scanning solutions, there are a number of options to choose from. Each have their merits, as well as associated downfalls.

For a long time X-Ray was the target for accuracy, as it results in a direct image of the subsurface. However, this method has health hazards and can be restrictive, expensive, and time-consuming. This is where ground penetrating radar (GPR) comes in.

GPR is fast, versatile, inexpensive, and can scan larger depths, as well determining the depth of subsurface objects. The issue with GPR comes with choosing a contractor. This method of scanning is down to the interpretation of the technician, and many companies simply lack the understanding to utilise the service to its full extent.

Xradar Enhanced Concrete Scanning is a new method of concrete imaging with the accuracy of X-Ray, and the safety and efficiency of GPR. Xradar technicians are trained to the highest standards and conform to all regulations within the industry.

The limitations of Concrete X-Ray

There are two types of X-Ray imaging – regular and digital. Both utilize the same methods, however, regular is processed with film and digital is processed digitally.

X-Ray imaging is limited to a 14" x 14" area, with a maximum of 8" depth, which takes time to process. This solution is expensive and due to the radiation emitted by X-Ray, an 80 ft clearance is generally required.

Once the image is processed it still relies on the interpretation of the technician to mark the image on the slab, which can result in errors. Unlike Xradar, when using X-Ray you cannot tell the depth of subsurface objects. This means that it is not possible to use it for anchoring and drilling, e.g. mounting to a slab.

The process of scanning concrete with Xradar is incredibly efficient and flexible. When scanning an area to core a hole you can know within a few moments whether the location will work, or if a new one needs to be considered.

There is no waiting for an image to process as an Xradar technician can accurately map the location and depth of subsurface objects in real time. The speed of Xradar means that it is far more cost-effective than X-Ray, while providing the highest levels of accuracy.

Compared to conventional GPR, Xradar can also distinguish between multiple layers of steel reinforcement. It can also map and locate objects hidden below layers of steel reinforcement and accurately determine the depth.
