Ground penetrating radar (GPR) is a non-destructive geophysical technique utilized in construction to analyze the subsurface conditions of a given site. By emitting electromagnetic pulses into the ground …

GPR uses high-frequency (usually polarized) radio waves, usually in the range 10 MHz to 2.6 GHz. A GPR transmitter and antenna emits electromagnetic energy into the ground.

Mar 30, 2026 · Ground penetrating radar (GPR) is an electromagnetic geophysical method that transmits radio wave pulses at select center frequencies into the ground to study the subsurface.

Highway professionals, contractors and engineers use GPR to measure asphalt thickness, compaction, and structural integrity with GPR with accurate real-time data.

GPR is a time scaled system which measures the time that it takes pulses of electromagnetic energy to travel from an antenna to an interface (e.g., soil horizon, bedrock, and buried feature) and back.

Ground-Penetrating Radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-destructive technique that allows the visualization of structures and features …

This non-invasive geophysical method is based on the interaction between electromagnetic properties and contrasting subsurface materials. That makes GPR technology ideal for detecting everything …

GPR works by detecting echoes of electromagnetic signals. First, the transmitter sends high-frequency radio waves (between 10 MHz and 2.6 GHz) into the ground. The waves pass through objects under …
