Is GPR safe?
Yes, it is extremely safe according to GSSI manufacturer and emits roughly 1% of the power of a cellular phone signal.
How does GPR equipment work?
GPR systems work by sending a tiny pulse of energy into a material via an antenna. These techniques send radio waves into the media and receive reflected signals (strength and time) to map structures and features buried in the ground or embedded in the media. Changes in the physical properties of the materials will create reflections that are picked up by the system. GPR can be used to obtain underground information such as geological structure differences, buried cables or conduits underground, voids or rebar detection within concrete slab etc.
How deep can GPR penetrate?
The GPR depth of penetration is primarily controlled by the material itself (e.g. soils types/ conditions or moisture level in the concrete) and also upon the antenna frequency being used for the survey. We will use suitable GPR antenna frequencies for your need.
What kinds of materials can we scan with GPR?
GPR will penetrate common materials such as soil, concrete, ice, rock, and asphalt. However, it works differently in these medias due to each material’s unique electrical properties.
What kinds of equipment does Scantec use?
We use mostly GSSI’s GPR products for our scanning services. We also utilize other high-end equipment from Radiodetection, Hilti, Trimble for other applications.
What antenna frequencies do we use?
As being said, we can provide a wide range of antenna selections for different applications:
- 200 MHz (Geotechnical, Engineering, Environmental)
- 400 MHz (Utility, Engineering, Environmental, Void Detection)
- 1600 MHz Handheld (Concrete Scanning for rebar, conduits, voids etc.)
- 2000 MHz Palm antenna for tight scanning locations (Concrete Scanning for rebar, conduits, voids etc.)
