Ground-Penetrating Radar

GPR transmits high-frequency electromagnetic pulses into concrete and records reflected signals from internal interfaces. It detects reinforcement, post-tensioning tendons, conduits, voids, and delamination planes without cutting or coring.

We deploy both 2D line-scan and 3D area-scan systems. High-frequency antennae (1600 to 2600 MHz) provide fine resolution in the upper 300mm. Lower-frequency antennae (400 to 900 MHz) penetrate up to 600mm for slab thickness and deep targets.

GPR is non-destructive, requires no radiation licensing, and produces real-time results. It can be performed on occupied buildings without disruption.
