Ground penetrating radar (GPR) is a geophysical method that uses high-frequency electromagnetic waves to image structure in the shallow subsurface (generally less than 10 metres). GPR is typically used to delineate shallow subsurface structures, commonly in urban or industrial environments. Due to its reliability, efficiency and non-destructive nature the technique is ideal for identifying potential hazards prior to drilling or excavation operations.

It is commonly used for:

• mapping shallow geology and depth to bedrock
• locating buried objects and landfill delineation
• detecting voids
• measuring slab thicknesses
• evaluating asphalt condition and thickness
• mapping archaeological sites
