Determining Groundbed Location For Cathodic Protection: What You Need To Know

Cathodic protection is a method used to reduce steel oxidation through an electrochemical process. Cathodic protection is used to protect buried or submerged pipelines, bridges, and large steel structures from corrosion, breakdown, and rust when an electrolyte (like water with salt and minerals) is present. The electrolyte serves as a conduit for the electron flow from the anode to the cathode. In steel structures where no electrolyte is present (like a steel building), they are best protected by galvanizing (zinc coating) or simply painting. 

The Exploration Of Aggregate Materials Using Geotechnical Techniques

Aggregate materials—like sand, gravel, crushed stone, slag, and recycled concrete—provide bulk and strength to concrete or asphalt. Large aggregate quarries and sand and gravel pits are located around most populated areas because of the high cost of transporting aggregate. (In fact, the cost of transportation from the mine to the consumer may even be higher than the actual cost of the aggregate.)

There are many different types of aggregate materials found in various geographic locations:

Behind The Scenes Of Groundwater Exploration With Electrical Resistivity

Early Methods Of Groundwater Exploration

To best understand how electrical resistivity surveys for groundwater exploration work today, it’s important to understand where resistivity testing began. 

Brothers Conrad and Marcel Schlumberger performed the very first investigation of how electrical current moves through the ground and what you can detect using an electrical resistivity survey in the early 1900s. From their research came what is now one of the most common methods of groundwater exploration, vertical electrical sounding (VES).

An Overview Of The IEEE Standard 81 Fall-Of-Potential Grounding Test

The Institute of Electrical and Electronics Engineers (IEEE) Standard 81-2012 “Guide for Measuring Earth Resistivity, Ground Impedance, and Earth Surface Potentials of a Grounding System”, suggests the fall-of-potential grounding test to be used to evaluate the capacity of an electrical grounding system—it is often used by subcontractors to power engineers.
