When it comes to subsurface investigations in Vancouver, two advanced technologies stand out: Ground Penetrating Radar (GPR) and X-ray imaging. Both are powerful tools for detecting and mapping what lies beneath the surface, yet they serve different purposes and excel in various scenarios. GPR utilizes electromagnetic radiation to create detailed images of the subsurface, making it ideal for locating utilities, detecting voids, and identifying changes in material properties. On the other hand, X-ray technology, offers precise imaging capabilities, particularly in non-destructive testing of concrete structures and other dense materials.
