Signature projects
  

Processing and analyzing data for 10-month long seismic TRT survey conducted by GD Test and Ghella (Italy) in a TBM excavated tunnel in Brazil;

Three-dimensional X-Panel^TM seismic tomography combined with Single Hole Reflector Tracing (SHRT^TM) conducted in one of the Rocky Mountain States to contour cavities posing threads of discharging their muddy contents into a tunnel being excavated below;

Imaging viaduct pile foundations in Pittsburgh, PA, using X-Panel^TM seismic tomography and SHRT^TM seismic ground imaging, and Borehole Magnetic Gradiometry;

Precise seismic location of old brick sewer in Pittsburgh, PA, using X-Panel^TM tomography and SHRT^TM ground imaging;

Detection of old mine workings using X-Panel^TM tomography in Sharples, West Virginia;

Characterization of deep solution mining cavities in Colorado using X-Panel^TM tomography and SHRT^TM ground imaging;

Geophysical investigation (X-Panel^TM, SHRT^TM, and Borehole Magnetic Gradiometry) for assessing unknown bridge
foundations in SW Colorado - for FHWA;

Assessing ground conditions around Zion-Mt.Caramel tunnel in Utah using Tunnel Reflector Tracing (TRT^TM) seismic
imaging - for FHWA;

TRT^TM ground imaging ahead of advancing tunnel face in Torino, Italy;

Three-dimensional X-Panel^TM tomographic imaging of geologic structure in exploratory studies facility in Yucca Mountain Project,
NV - for US DOE.

All surveys were conducted using swept frequency sources of C-Thru Ground's own design coupled to the ground either mechanically or through water. Broad frequency range generated by those sources, and recorded by the proper digital surveying equipment contributed to a high resolution of  imaged ground features.

Technical support

TRT^TM and X-Panel^TM applications licensed to Kajima Technical Research Institute, Japan, and used for imaging ground conditions ahead and around excavated openings;

TRT^TM applications licensed Olera Technologies and used by numerous tunnel developing customers in China.
