Ground-Penetrating Radar (GPR)

Olivier International uses ground-penetrating radar (GPR) to non-destructively investigate subsurface conditions and locate detectable metallic and nonmetallic utilities, voids, reinforcing steel, and other features. Detection depth and reliability depend on antenna frequency, target size and depth, soil conductivity and moisture, surface access, and site conditions, so GPR is often combined with records and complementary locating methods.
