Greetings!
Pyramid Geophysical Services (a subsidiary of Pyramid Environmental & Engineering) is expanding our geophysical capabilities, and we want YOU to be aware of the services we can provide.
A note from Eric Cross, PG:
"I am excited to bring new skill sets and knowledge of geophysics to the North Carolina region through my work at Pyramid. I believe that the future of rapid site characterization, geotechnical engineering, and subsurface investigations lies in the coupling of geophysical methods with traditional sampling techniques. Please contact me to learn more about how our services can assist you."

What is Geophysics?
The non-invasive investigation of subsurface conditions in the Earth through measuring, analyzing and interpreting physical fields at the surface. Some studies are used to determine what is directly below the surface (the upper meter or so); other investigations extend to depths of 10's of meters or more.
|
Applications of Geophysics
- Characterization and depth to bedrock, permeable pathways for groundwater flow
- Landfill delineation and characterization
- Investigation of boring sites for geologic characteristics and interferences
- Location of Underground Storage Tanks, landfills, abandoned wells, utilities, rebar, drums and voids
- Water supply investigations, hydrogeologic site characterization, and groundwater quality mapping
- Geotechnical investigations
- Roadway mapping (integrity, subsurface characteristics)
- Karst Investigations
|
What are the Benefits of Geophysical Surveys?
- Rapid assessment of site geology and subsurface characteristics across large areas
- Continuous profiles
- Non-invasive techniques avoid the need for extensive drilling, groundwater sampling, and disturbance of the property
- Cost-effective
- Portable equipment
- Can provide multiple data sets with a single survey (i.e. buried debris and contaminants, geology, groundwater table, geologic hazards)
- Avoid unnecessary sampling (drilling, monitor wells)
|
Geophysical Services We Offer:
Electromagnetic Surveys (EM)
Electrical Resistivity (ER) Surveys
Ground Penetrating Radar (GPR) Surveys
