Structural defects


Ground Penetrating Radar (GPR) is a spectral electromagnetic technique used to determine the distribution of subsurface media. GPR uses one antenna to transmit high-frequency, broadband electromagnetic waves, and another antenna to receive reflected waves from subsurface interfaces. As electromagnetic waves propagate through the medium, their path, electromagnetic field strength, and waveform will change with the electrical properties and geometry of the medium they pass through. Therefore, GPR has been widely used in non-destructive structural testing.

The test data shows that there is a structural defect (cavity) underground at a depth of 60-70cm. The results confirm this.
