Ground Penetrating Radar (GPR) for Geotechnical Investigation of Dams

Ground Penetrating Radar (GPR) Systems non-destructively assess and evaluate dams and related structures.

GSSI is the world leader in the development, manufacture, and sale of ground penetrating radar (GPR). Its equipment is used all over the world to explore the subsurface of the earth and to inspect infrastructure systems non-destructively. GSSI created the first commercial GPR system over 50 years ago and continues to provide the widest range and highest quality GPR equipment available today.

Dams are engineering structures constructed for different purposes and vary in sizes, shape, and types. As such, characterization of the structure and substructures can be challenging and require multiple geophysical instruments. Ground Penetrating Radar (GPR) is an established and safe non-destructive testing technique for subsurface exploration. It provides a quick and high-resolution survey option.

GPR used for dam investigations can provide information on sediment build up, rip rap monitoring, and leak or void detection.
