THG has a wide range of geophysical equipment and expertise available to collect and interpret both surface and downhole geophysical data. We can access piezometers, monitoring wells, and test borings that are located in areas that are inaccessible to traditional logging vehicles.

The design of foundations for industrial and commercial structures may require measuring the elastic properties of the subsurface materials. We can collected and analyze data for the design of foundations for many different commercial structures and utility applications.

THG prides itself in developing innovative data collection and processing methods to improve data quality and minimize costs to our valued customers. Our environmental projects often involve land-filled waste delineation, identification of buried objects and hazards, delineation of bedrock fractures related to groundwater contaminant pathways, and many other geophysical survey applications.

THG provides detection of fracture points of sedementary rock formations tht may cause potential subsidence under a structure.

THG uses a modified common electrical method to test for the presence or absence of cuts or holes created during installation. These methods provide the landfill operators an extra level of confidence in the security of their landfill cells.

THG can map and document utilities in detail with every survey project when specified. Our highly qualified team members have the tools and skills to identify utilities for both engineering and environmental purposes

THG can provide detection and monitoring of sinkholes, caves, mines, aquifers, and many other underground anomalies for industrial purposes. Precise identification provides information for engineers to correct the solution or relocate with certainty.

THG is a comprehensive geophysical company providing Wind Farm services through a variety of methods and uses such as, Electrical Imaging, Electrical Resistivity, Vertical Seismic Profile, and Multi-Channel Analysis of Surface Waves.
