Ground Penetrating Radar Operation
The Ground Penetrating Radar (GPR) has a high frequency radio wave pulses to detect the echoes that return from within the material.
These discontinuities can be metallic and non-metallic pipes, conduit, sewers, post tension cables, cables, cable ducts, voids, foundations, reinforcing in concrete, cavities, transitions between soil and rock, filled areas, or buried objects.
This radar inspection can detect voids within concrete slabs and under concrete slabs, prior to concrete cutting, sawing, drilling, grinding, demolition and excavating, is a needed part in establishing a safe environment and is very cost effective.
When concrete is initially poured, it has a high free water content which causes both high attenuation and low velocity.
As curing occurs, hydration removes free water and locks it into the concrete structure resulting in an increase in velocity and a decrease in attenuation.
This latest technology can analyse concrete at depths up to 0.5 to 1 metre using 3D imaging. This system is user friendly and only requires one operator.
The GPR X-raying can conduct a concrete inspection of concrete block walls, concrete floors, concrete slabs, airport runways, tunnels, dams, and garages. Asphalt roads and surfaces can also be scanned.
Concrete X-ray Services uses a 1000 MHz Deep Penetration Concrete radar head, which is a high resolution antenna used for high quality radar measurements.
GPR utilizes different bandwidth antennas depending on the desired result of the survey being done.
