Site specific ground problems?
C-Thru Ground, Inc. (C-TG) was created by a senior geophysicist who used to work for NSA Geotechnical Services, Inc., until it terminated its activity in the ground imaging business at the end of August 2004.
The C-TG founder brings to the company his skills and four decades of hands-on experience using and developing new seismic surveying techniques and applications both for a passive monitoring of stress release phenomena (microseismic), and for an active imaging of ground properties (2D and 3D velocity and/or attenuation tomography for transmitted seismic waves, 3D seismic reflection, and secondary seismic radiation).
In November 2004 C-TG has acquired all the assets of NSA.
From the start C-TG continues providing uninterrupted ground imaging services for former NSA customers both domestic and overseas. Combining former NSA expertise and technology with less overhead allows us to offer the same and even better quality service for a reasonably lower cost and in real time as defined by needs for the decision making.
This includes offering services developed recently in NSA or improved by C-TG that are listed in Our Expertise.
Also from the start C-TG remains actively involved in promoting continuing development and bringing to the market new software and hardware. Significant part of this development was initiated and advanced by NSA under Advanced Technology Program (ATP) award granted by National Institute of Science and Technology (NIST) that ended in August 2004.
C-TG supports continuation of this development on a sub-contract basis by other professionals, former employees of NSA, who started their own companies pursuing individual goals stemming from their involvement and the conclusion of the ATP award.
Furthermore, C-TG has completed building a more powerful swept frequency seismic source. C-TG also continues developing a mechanically coupled receiver assembly for dry borehole applications particularly in underground openings. This new equipment will enhance resolution and range of seismic ground imaging for civil and mining engineering.
C-Thru Ground, Inc. is also looking for cooperative agreements with other companies both at home and abroad that are involved in geotechnical ground characterization who would be interested in conducting surveys in their territory with their own equipment, and with data processing being carried and turned around by C-TG. This would further reduce the cost of ground imaging for the client by reducing often expensive cost of travel and shipping of the equipment.
