Case Study

Accurately Locating Subsurface Utilities in Wet Ground Conditions

In bad soil conditions or heavy rainfall, the ground is wet and soggy with the dielectric value at very high levels, making GPR investigations more challenging. See how stepped frequency continuous wave technology achieves the perfect mix of both penetration depth and resolution, even in these...

Case Study

Inspection of non-metallic pipelines and subsurface stratification

For this project, a team of engineers needed to detect subsurface non-metallic pipes and underground stratification on a section of highway in China, to ensure safety of the pipeline during construction. See the results and how it was...

Case Study

What Lies Beneath: The Use of Subsurface Mapping GPR in Clandestine Grave Research & FBI Investigations

This case study looks in detail at research being conducted at Youngstown State University (YSU), using ground penetrating radar (GPR) to locate clandestine graves. The project aims to improve the understanding of human decomposition and to train law enforcement on the use of geophysics in...

Case Study

Mining Data Gold with Subsurface GPR

To avoid any potential threats to the environment or future building, CSGeo was tasked with scanning old mineral mines in Austria for more information. See how they did it and the fascinating...

Case Study

Finding the Remains of Fort Visalia with Subsurface Mapping GPR

Fort Visalia, built in 1852, was considered the birthplace of Visalia city in California, however the exact location of the fort structure was never confirmed. See how the team at ASM Affiliates used subsurface mapping GPR to reveal the remains of Fort Visalia at The Old...

Case Study

Detecting and Mapping the Majang Lava Cave World Heritage Site

Geophysical company, His Earth Co. Ltd, needed to confirm the distribution, depth and exact location of the underground Majang lava cave to protect the site before land development. See the details and results of this unique GPR survey on Jeju...

Case Study

Locating Subsurface Utilities with High Precision

Locating the exact positions of subsurface gas, sewage and water utilities at different depths can be a challenge. See how GPR synchronized with the GNSS (Global Satellite Navigation System), allowed us to precisely map subsurface utilities made from various materials and located at different...
