Ground Penetrating Radar
This is a non invasive method to do material analysis based on transmission of electromagnetic waves of ultrawideband (UWB) in materials; ranging from 10MHz to 2.6 GHz. A part of the electromagnetic wave is reflected when a limit is reached between two materials with different electrical properties. The reflected signal is recorded and shown to the operator and its frequency recorded for further analysis. The most common applications are: Geological and geotechnical studies deeper than 80m, cavity detection, subterranean water prospection, detection of faults and fractures.

Applications
-Mapping bedrock configuration and depth
-Identifying karst features, voids, and burrows
-Locating pipes, tanks, and other utilities
-Delineating soil horizons and soil stratigraphy
-Determining ice thickness
-Locating the groundwater surface
-Determining water depth in lakes
-Mapping fractures, changes of rock type, and rock fabrics
-Identifying and mapping the extent of groundwater contamination
-Detecting unexploded ordinance and unmarked graves
-Studying moisture/gas dynamics in soils
-Locating lava tubes
-Monitoring tree root distribution and health
