How to accurately scan and transfer core location for a 24-inch thick slab? Many times we have been asked:”What is the maximum depth you can scan a slab?”. The answer is: It depends!.
We have all the necessary tools to maximum the penetration depth. For general concrete scanning purposes such as cutting and coring, probably 900 MHz is the lowest frequency we use which designed up to 3ft (1m) of penetration. More common, 2000 MHz and 1600 MHz GPR antennas are used to “see” down to around 1ft.
However, the accuracy and the investigation depth can be increased by using the combination of tools with knowledge and experience.
We currently successfully completed a scanning project in NW Calgary for 24in – 36in thick slabs with use of multi antennas on both side of the slabs and EM equipment.
The scope of work was to scan beams and column caps prior to coring. The slab itself was approximately 12in thick, the caps were 12 in thick with dense rebar.
Hilti’s PX-10 Transpointer
Transpointer was used to map the scanning result from the bottom to the top of the slabs.
