8 Most Common Types of Excavation

types of excavation

According to the U.S. Department of Labor, reducing hazards while excavating and trenching is a priority. No matter what types of excavation you may need, understanding the differences can do more than save you money. In some cases, it can keep workers safe. So, what is excavation, and how do you know the differences?

Contractors today work with excavation technologies that have reshaped how the world approaches earthwork. Find out more about how these methods can benefit your project by reading this article!

1. Underground

Out of all excavation types, this method may be the first that comes to mind for most Americans. Permits alone can complicate the process, but this also requires various tools and techniques. Tunneling is a frequent need that this meets, which can become especially difficult or dangerous to plan for without the right experience. 

2. Stripping

A significant number of construction sites need stripping excavation before projects can progress. This method often involves creating wide and shallow sections of almost any material, including soil, gravel, and sand. Beyond construction projects, this can also become necessary for erosion control as mandated by the U.S. Environmental Protection Agency

3. Trench

Trench excavation often precedes plumbing jobs that need to lay pipe. This process ends with long, but not deep, digs into the earth. OSHA has strict standards around this work due to the risk of severe injury from trench collapses or cave-ins.

4. Topsoil

While stripping often involves removing topsoil, this section represents a different type of excavation project. Someone who needs this done wants to remove all vegetation on the upper portions of the property.

5. Footing

Creating a footer during excavation involves removing earth from previously measured areas. These jobs often need a steady hand to create the appropriate depth and shape. 

6. Borrow

As the name suggests, this excavation means taking material from one site and adding it to another. If the builders don’t have enough of what they need locally, they may need to bring in what they need for fills or embankments.

7. Earth

Earth excavations typically occur after the topsoil gets removed. The depth of the project often varies based on the plans for the structure. Depending on the It’s often used for laying concrete foundations for buildings or drainage ditches.

8. Dredging

Dredging may occur underwater or partially on solid ground. This excavation becomes necessary to create coastal protections for a beach-front property. It can involve removing thousands of pounds of earth and sediment, depending on your needs.
