Concrete scanning, or concrete imaging, is a vital step to take when preparing to cut, core, or drill into a concrete structure.
This process primarily involves the use of ground penetrating radar (GPR) technology. This non-destructive detection and imaging method involves sending a radio signal into a structure and reading the “bounce” that occurs when the signal encounters a material. An experienced GPR technician interprets this reading to determine the type of material located.
Perform accurate measurements
The Strengths
- Single Rebars are very sharply identified in a scan.
- An air layer or a gap can easily be seen.
- Non-metallic surface coatings do not have an effect on the results.
Weaknesses
- It is difficult to provide good results in densely reinforced concrete or beyond a steel plate
- It is difficult to identify small delineations or changes in a concrete element.
- Limited penetration through freshly poured concrete.
