What Can Concrete Scanning Reveal?

Concrete scanning is a non-destructive method of evaluating the integrity of a concrete structure in place. It uses ground penetrating radar (GPR) to detect materials or voids within a concrete slab, and can be used to scan slabs-on-grade and other types of concrete that can only be accessed from one side. GPR does not produce images, but data that can be interpreted by a trained analyst to identify the location and type of feature within the concrete. X-ray concrete scanning is also used in the construction industry, but it has some limitations.

It can only scan one side of a structure, and the images produced need to be developed off-site. In addition, digital radiography requires access to both sides of the concrete slab and is not suitable for scanning the concrete of the slab. GPR scanning offers several advantages over X-ray scanning. It can help you perform quick scans of a large area with significant savings in time and labour costs compared to X-ray scanning.

GPR signals may be inhibited or bounced if the scanned slab has a significant water or moisture content, but this can be addressed with proper preparation. You also do not have to evacuate a construction site for fear of exposing other workers to radiation, as would be the case with X-ray scanners. The data produced by GPR must be interpreted once the scan has been completed to identify the types of features present in the slab. By cutting concrete without scanning it first, there is a chance that you may encounter an underground object or hazard.

Concrete scanning can help you avoid this risk and save time and money on your project.
