WHAT IS GROUND PENETRATING RADAR??
Ground Penetrating Radar (GPR) is a nondestructive method that uses electromagnetic waves to gather subsurface images that are analyzed and interpreted for locating buried utilities, geotechnical investigation, archeological investigation, heritage conservation, and locating Unexploded Ordnances (UXOs).
Ground Penetrating Radar works extremely well at visualizing concrete floors, walls, decks, slabs, tunnels, balconies, warehouses and garages. It is able to locate rebar, tendons, conduits, and voids, as well as measure slab thickness. Generally this is done with access to only one side of the element. It is vital to have knowledge of the position of obstructions within the concrete before drilling, cutting or coring.
Ground Penetrating Radar is an excellent tool for the location, investigation and determination of the extent of footings and foundations. The quantity of trial pits (test pits, pot-holes) essential to determining foundation and footing detail may well be greatly reduced, saving time and money.
Ground Penetrating Radar is currently the only non-destructive technology able to locate both non-metallic as well as metallic subsurface utilities. It is ideally suited for locating utilities including water, sewer, gas, electric, telephone, cable and fibre optic.
