Concrete Imaging and Scanning generally refers to a group of non-destructive tests (NDT) that used to obtain post -installation information about concrete structures. Several Imaging and Scanning technologies have been developed over the past few decades but one key one for the telecoms industry is Ground Penetrating Radar – GPR
Concrete scanning might become necessary in different situations:
- structure inspection and condition survey of existing buildings,
- locate and size steel rebar in slabs and walls,
- determine rebar spacing and estimate concrete cover
- locate defects such as voids and discontinuities in concrete slab on grades.
- locate live conduits ahead of coring and drilling.
- Corrosion inspection and monitoring
Ground penetrating radar (GPR) is a widely used non-destructive method for scanning concrete. GPR uses pulsed electromagnetic radiation to scan concrete. GPR consists of a transmitter antenna and a receiver antenna, and a signal processing unit. GPR emits electromagnetic pulses (radar pulses) with specific central frequency to scan the subsurface medium. The reflected waves from subsurface layers, and objects are captured by the receiver antenna.
Ground Penetrating Radar provides a cost-effective approach for scanning large areas. GPR scans can be performed at traffic speed (ideal for large areas, such as rooftops.
