THG provides full service mapping of bodies of water
for both commercial and environmental utilization.
Resulting terrain maps provide our clients with
data that helps them focus their investigations
or improve the accuracy of their design specifications.
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
Utility & UST Investigation
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
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.
