Ground Penetrating Radar 3D Scanning
Ground Penetrating Radar 3D Scanning that is designed to find buried pipes and cables using Voxler proprietary systems. GPR features include high resolution technology which selectively enhances deliverables. Ground Penetrating Radar (GPR) exposes anomalies, non-metallic, inaccessible, unknown objects or abandoned utilities that cannot be located with traditional cable and pipe locators. When this occurs, Ground Penetrating Radar (GPR) must be used in conjunction with utility locating. GPR is a non-invasive, non-destructive geophysical surveying technique that is used to produce a cross-sectional view of objects embedded within the subsurface.
Reflections are produced in the data screen profile (on the control unit) whenever the energy pulse enters and exits contrasting subsurface materials. The way it responds to each material is determined by two physical properties; dielectric constant and electrical conductivity. Since the GPR emits electromagnetic energy, it is subject to attenuation (natural absorption) as it moves through a material. Energy moving through resistive (less conductive) materials such as dry sand, ice or dry concrete will penetrate much further than energy moving through absorptive (more conductive) materials such as salt water or wet concrete. As a result, the greater the contrast in electrical conductivity between the material one is scanning through and the target one is searching for, the brighter the reflection; high conductive materials such as metals produce the brightest reflections. Our (GPR) Ground Penetrating Radar units are equipted with proffessional grade (GPS) Global Positioning Systems.
