GPR (Ground Penetrating Radar)
Ground Penetrating Radar (GPR) is a tool used to see what's hidden underground without digging. Think of it like an ultrasound for the earth. Surveyors and engineers use GPR to find buried utilities, check road conditions, locate archaeological remains, or inspect structures. It works by sending radio waves into the ground and creating images based on what bounces back. This helps companies save time and money by identifying underground features before construction or exploration begins. Similar technologies include electromagnetic surveys and seismic testing, but GPR is often preferred because it's non-destructive and provides clear, detailed images.
