In past newsletters we have provided a variety of geophysical case study examples that Pyramid has completed over the years. These projects have showcased methods such as electrical resistivity, seismic testing, electromagnetics and ground penetrating radar that were used to investigate the … [Read more...]
July 2020 Newsletter: Density Anomalies and Geophysics – Concepts and Methods
In general, the density of the earth increases with depth, from a lighter silicic crust (or basalt in the oceans) to a sequence of denser, more metallic rocks from the mantle to the inner core. This is what we expect when digging or drilling into the earth. But occasionally we are surprised by the … [Read more...]
July 2016 Newsletter: Concrete Inspections and GPR – How Does it Work?
Ground penetrating radar (GPR) has a multitude of uses, many of which we have discussed in past newsletters. Applications include the detection of underground storage tanks (USTs) and drums, geologic mapping, void detection, archeological investigations, and subsurface utility locating. In addition … [Read more...]
May 2016 Newsletter: Private Utility Locating – What’s the Deal?
It is common for all of us to see technicians along the side of roads with hand-held utility locating equipment. Typically they will mark their findings with spray-paint and/or pin-flags. What, you may ask, are they doing exactly? And the answer is they are locating and marking subsurface utilities … [Read more...]
Ground Penetrating Radar | GPR
Pyramid Environmental has years of experience utilizing Ground Penetrating Radar (GPR) equipment and processing software to analyze geologic site conditions, evaluate the nature and integrity of subsurface strata, and locate buried objects such as UST's, drums, or waste/debris. We typically use our … [Read more...]
